I just bought a pair of Discovery II Facelift Headlamps for D15KOE ....
The lenses need a little polishing as they have started to discolour slightly at the bottom, but they aren't scratched or owt, and they've gotta come off anyways as I have a spare pair of Projectors in the Loft for a Bi-Xe 5000k conversion :D :D :D

Left Headlamp, the Right one is on it's way ....



Lotsa surgery required to fit these, have to cut the PFL lamps mounting plates outta the D15KOE's front panel and touch in the paint to avoid rust, plus paint the "Hockey Stick" Trims that go underneath them as I could only get Blue ....



And so ................................................. When I get bored over Christmas ...................................................

You'll work on an R170?
When the D15KOE is finished I will be working in earnest on two R170's, it will be time the Silver V6 was getting it's Paintwork finished, then converted to 7 G Tronic.

When that's done the D15KOE will head south and collect another W220 V8, for the Silver R170's V8 Conversion. Then the Blue V8 R170 will get it's Paintwork sorted, (1 new wing and rear arches), finally a 7 G tronic will get fitted into that one ;)

So it will all be R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170, R170 .

I'm sure /\ /\ /\ that little lot will more than make up for me being a no good off topic D15KOE waffling git over the last few months with my current project, which of course was only obtained so I had a nice 3500kg capable Tow Car to tow R170's and V8 Donor Cars from England to here, where I can then Modify R170's

:p :p :p

OK, back to the Android install, which is relevant for R170 Owners because it is a Single DIN and Wiring and other procedures are the same.

So this particular ERISIN will not play WMA Files, a short while ago I bulk converted (one album at a time) some 50 Albums / 900 + Tracks to MP3 using a converter software .....................

Then all my albums played fine and also can play all 900 + Tracks at random, I use that function a lot, by using the "play all random" function.

So the next issue is that most of my Albums now converted to MP3 wouldn't take advantage of the Tech of these units, so you didn't get the Album Art and the Artist / Track Name / Album Name etc would just display as unknown. Even the track title was using it's actual file name :cry:

So this is a T.Rex Album, pre sorting its metadata out, and shows how it played on Screen, note the lack of Album Art on the Music Player Apps rotating "Turntable" and the missing Info !!
Pah!! that's pants, no good at all, winds me right up being a semi-retired pro DJ :ROFLMAO:
They all worked fine on other H/U's and my gigging laptops when in WMA format, the MP3 Converters screw them up :( ....



Yeah yeah, I am anal, but read on ....................

Most that wouldn't play were the older ones that were ripped from my CD's years ago on Windows Media Player. There were only about 5 or 6 Albums that gave all this info flawlessly and they were MP3 Albums Downloaded from Amazon Music in more recent years....



I tried editing in VLC and other freebies, with mixed results :(

So I then came across Audio Ranger ................


....



Ok, so first up I download it, first look see the free version will only do 20 tracks at a time, and annoyingly it will give you countdowns at each stage, thus taking time, but because it was so easy to install and intuitive to use I soldiered on :D

I did one Album first and went tried it in the Car via USB ........... Absolutely perfect :D
All info working and the Album Art comes up and rotates on the "Record Player Turntable" on my Androids Media Player, yay YAY !! Woo hoo !! ....



This is exactly wot I need (but would be better if I could do like batches of files say 200 tracks at a time) ;)

I now soldier on with the free version and get all the Artists with "A" done, i.e. ASWAD, Anastacia etc etc.

Now I go test them, jobs a good un :) Next thing, by the time I've done the "B's" it stops working and tells me I need to pay £17 odd to upgrade to the full Pro Version .................
Being very happy at last I had found a program that actually works very well I took 2 minutes to pay the one off payment and enter the immediately EMailed licence Key.
Back up and running al full speed ahead now (y)
Well worth the money, I've tried the freebies, they are all glitchy and not easy to use, so don't bother trying to tell me I shoulda used "xyz" freebie, IMHO Audio Ranger was well worth a measly £17 !!

Hell ya cannae even get pi pie eyed for £17 lol

Spent most of yesterday arvo doing Albums in batches "C" "D" "E" etc etc and with some minor edits to a few File Names after it had finished doing all the Meta Data, I had a fully working set of all my favourite Albums in a new "Car Music MP3's" File ;)

So I deleted all Albums from the Android, and put the new set on a USB Stick, use the Androids "File Manager" App and save them all to the units internal memory, "Music" file and start playing :)
Brilliant, all now working flawlessly, an added bonus is that if there is too long a track title or something it actually scrolls across whilst playing, this just shows the power of these Android Head Units if you can be bothered to take the time to set them up properly, which in this instance includes the Files you add on :)

Pixels taken by a very happy bunny ....



















BTW, did I mention, behind the Front Panel is a DVD / CD Slot .......................

Pink Floyd, the Sound quality and Light Show is amazing, shame my pix's don't do it justice :D :D :D ....











So coming next over the holidays, pull a bunch of trim out and at least install the Sub and Reversing Camera, I will blag the use of my buddies Tyre Machine in the new year and fit the TPMS Valves and then the D15KOE install will all be finished :)

I can also add all my new "MP3 Car Music" Files onto the other 4 Mercedes we possess :)

More soon ............................................................................

Local causes a multi-vehicle accident because he was too busy watching the music video with the scantily clad dancing ladies
Actually, there is a connection on the Android Head Units to Parking Brake switch, so it doesn't play DVD unless stationary with the Handbrake on .................

Not that I connect that up on my own cars, 'cos I ain't dumb enough to watch a Movie whilst driving :ROFLMAO:

So you want to fit Steering Controls to your Android Install in yer R170 :)

A word explaining Androids and Steering Wheel Buttons ................
The Androids all have 2 methods to receive Data from Switches ..............

1) Resistance based, these were fitted by a lot of mfrs before CAN became common place. Basically one side of the Switches are earthed, and when pressed the buttons all give out a different resistance to Earth. The Android has hard wires SWC1 and SWC2, so you can wire the Resistance output, and then in one of the Menus on the H/U you simply press each Switch in turn, tell the unit what you want that Switch to do by tapping an on screen Icon, then hit OK. You can also select 2 functions per switch, Short (Button) Press and Long Press ;)

So this is a diagram of how the switches work with just 2 Wires exiting on left side of Diagram ....



2) CAN Bus Based, use the correct CAN Adaptor for MB and plug and play ............... That only works with MB's that already have Steering Wheel with Butons, (they have a suitable CAN, like say R171), the humble R170 does not ;)

You could go the route I did on my V8 R170, which is to fit a later R171 / W203 facelift Steering Wheel, but that is very complicated trickery because R170 doesn't have a suitable CAN Bus,so I had to do a lot of Micro Soldering on the Switches tiny PCB's to convert them from CAN Bus based to Resistance based, then I had to find a suitable Steering Angle Sensor (Clock Spring) that had more wiring cores, and that wasn't a quick swap in, it enabled a few mods which required it being carefully stripped down ............. Not for the faint hearted / electronically challenged ;)

That is covered in the early pages of this very thread if you like pain :D

So lets look at an easier way, as we can compare it to the D15KOE Install ;)

For R170 "easy" Route I recommend buying a Switch Set from a resistance based vehicle, and installing it on your Column Shroud, something like the D!5KOE Switches should install neatly, and within reach of a finger whilst hands are on the steering wheel, the metal bracket easily unscrews making them very compact behind the Column Shroud ;) ....



I do believe some Peugeots etc used a little Stalk for Media Control that was resistance based, and could be cool if ya can fit it on the Column Shroud neatly, not my intention to do the homework / R&D, just explaining how it works, and should be well within the scope of a decent DIY'er with basic wiring knowledge ;)

So the D15KOE Switches are set in the H/U menu to ....................

Volume + .... Short presses give single steps Volume up / Long press gives scroll Volume up
Volume - .... Short presses give single steps Volume down / Long press gives scroll Volume down

Mode .... Switches between stuff like Media Player, DVD, Radio, Phone, Navi, Torque Pro, TPMS etc etc etc, i.e. MODE !!

I> button .... Short presses next Track / Radio Station / Long press = Call Answer
<I button .... Short presses previous Track / Radio Station / Long press = Call Hang Up

There you have it, very simples as a DIY ;)

FWIW, I have the LIN bus (not CAN bus) that is in the MB steering wheels working on the bench for W204, W205 & W216. Other model wheels would be fairly straightforward to decode, now that the code has been cracked on these. This is part of a LCD instrument cluster conversion I am working on. When complete the steering wheel will work with the stock type R170 clockspring, and have an Arduino based computer sitting in the dash that will repurpose the existing wiring. On the other side of this board will be several relays, digital and analog I/O. It can also grab the LIN bus data, and give things like a relay output for the horn, digital outputs, CAN and more. It can also pick up messages from the car's existing CAN bus, to pass things like interior lighting back to the wheel for the button backlighting (it works!). The board has three CAN busses (including one CAN FD) and two LIN busses onboard. The idea being that I will create a local CAN-B (83.3 or 125kbps) for the radio, and anything else interior LAN I'd like to add, and then at least one CAN-C (500kbps) so that things like the shift paddles will talk to the TCU. There are about a dozen digital inputs (0-5 or 0-12v, selectable), 4 analog inputs, several 5A relay outputs, and a handful of open collector digital outputs. The boards have been made, I'll post up some pics soon.

The next hard part will be how to mount the wheel in the R170, and make it look proper. There is a little bit of modification needed to the backside of the wheel to get it to sit properly, and a piece of trim that will probably need to be fabricated. When complete, it should function exactly as expected. I will be using a W205 wheel in my car.

In other words, it would make your Android steering wheel controls a snap, without micro-soldering the switches. I am thinking about open sourcing the entire board and baseline code. It could be used for a variety of purposes and on a variety of vehicles, simplifying the prospect of adding newer electronics (toys) to your older platforms. Cost is not through the roof, either. I wanted this to be accessible to most budgets, including my own.

I doubt it would work with an Android unless you built the decoder to go with it. Not really for a DIY'er on his R170.

It's good work you are doing, but a bit above the average Joe ;)

Not really, actually. While the board is capable of a ton of things, a basic code set, designed for a few key functions can be had rather easily. For instance, with some instructions or a how to article, a person will be able to download pre-written code, flash it to the board (USB), and then wire up the board according to the how-to article or forum thread. As for Android, the idea is that the board speaks 'standard' MB CAN-B (infotainment/interior) bus messages, so volume +/-/mute/etc will all be accessible to the radio. Most of the android units go into a "learn" mode for CAN messages, and you simply push a steering wheel button, and the radio registers the message. You assign it on the radio to be volume, tuning, mode, etc. ALL of this sounds more complicated than it actually is.

I hope to open source the boards to encourage collaboration, and if done properly, someone on one of these forums will smell an opportunity to make a few $$$/£££/€€€/₿₿₿ and will offer up steering wheels, ready to go (literally all that needs to happen is that the mounting on the back side of the wheel needs to be milled down (or even crudely - hit with a grinder). Once all of the coding and fabrication is taken care of, then the rest of it bolts/wires together rather easily, and normal DIY'rs can take it from there.

Of course, none of this can be the normal type of plug and play that many more modern MB enthusiasts are accustomed to, because we are talking about not merely adding parts to a car, but making several generational leaps in technology, all at once. But for the enthusiast who wants to keep their ever increasingly classic R170 rolling, and keeping with the times, then this may open the door to many modern amenities.

I'm not looking to make any money on this. I designed the board for my own and my son's R170s. If other people can benefit from it, I am happy to share.

1) That sounds good, that would work for the likes of the Android in my V8 R170. I thought you were talking about using the later LIN info ;)
However I'd not change that one now it is all hard wired, my Paddles are hard wired too, and they are faster than the Tiptronic Stick and Paddles in some of my other older MB's ;)

2) Of all the Androids I've fitted, (around 10 now), to earlier MB's with B CAN none of them needed teaching in, CAN was automatically recognised .......... W220's W203's, C215's etc

The teach in procedure is, (on those head units), for the Resistance based Switches ;)

The later Cars with NTG4.5 etc like the HK in our AMG W212 Wagon, well no point fitting an Android, that unit will do everything I want that an Android does ;)
The only thing I did with our W212 was fitted a retrofit Reverse Camera because it never had that option, but that was just a matter of Wiring, an Interface Box, and configuring COMAND to accept it ;)

All packed up for the Holidays as of yesterday, many D15KOE parts here to be fitted, finish off the Android Install first, then a load of other stuff :)

I'm going AWOL today, off to Bonar Bridge, (2 hr drive across from NW to NE Highlands), to see ma buddy Roddy before Christmas and blag some more little hard to find bits for D15KOE ...............

Namely the bitties (I think) are required to fix the Door Lock barrel that failed and spectacularly left me locked out in a hooley of a storm a few weeks back ;)

Remember the D15KOE Door Lock Barrel that suddenly decided to fail and lock me outta the D15KOE, yup, as expected, the Rod between Barrel and Door Lock had sheared across where the tiny locating Pin holds it into the Barrel.

I came back from Bonar Bridge yesterday armed with a good Door Handle, Link Rods and a complete Drivers Door Lock assy as I hadn't stripped the D15KOE's Door down and wasn't certain exactly wot went tango uniform !!

I also came back with what looked like half a Pig, from Swordale Farm, a huge smoked Gammon Ham for Crimble which was likely sawn off said oinker first thing that morning, rude not to really 🤣

I started the fix last evening, by removing the Door Handle and then removed the Barrel from D15KOE's Handle, swapping the Rodamabob and then rebuilding a Door Handle assy out of all the bestist parts.

I then installed the handle with my Door Lock Barrel this morning, jobs a good un ;)

I gotta be honest, now I've seen how that thing is designed, I'll not be using it a lot, it is purely designed to get ya into the car in an emergency, and so I better move fixing the Fobs Plip issue higher up the priority list ;)

I know exactly what you mean. One of my cars is dead, battery dead, doors locked and you can't unlock the doors because.....no surprise, the little rod between lock cylinder and door actuator sheared.

You can unlock the trunk, but you can't get inside because the gas tank is behind the seats. The battery is under the rear seat.

There is a seriously convoluted way that I can use to get inside without breaking anything, but it's such a process that I've just let it sit and drive my other cars. I'm not going to subject myself to that kind of hell....yet. :ROFLMAO:

So little dead piggy is going to sit where he is. :ROFLMAO:
