Hi Folks,


I currently have a 2002 R170 230 with the standard "MB" radio / CD player and I'm thinking of upgrading it.


I'm looking for a DAB system with Bluetooth, aux connection and possible Sat Nav.


What have you guys fitted to your SLK's ?
(Any photos????)

Any decent audio will be an upgrade on your old stereo unit .
Years back i fitted a Alpine unit diff in sound was a huge gain alone .

Sold car and fitted a cheap £50.00 pioneer unit and drop in sound was heard .

Do you have the bose system? If so, be sure to get a unit that has 4 volt outputs. You'll connect them to the bose system and use those amps. No point in spending extra to get a high output head unit as you'll only be using the pre-amp outs.

Can you let us know if you have speakers behind the seats? If you have, then you have a Bose system and you have a harder job upgrading. If not, that's just great! Your upgrade is nice and easy (except perhaps sat nav).

The SLK has a standard ISO system installed which suits most after-market head units - but the slot is only single-DIN which limits your options regarding Sat Nav. You can get head units with Sat Nav that fold out a larger screen, but of course these then block the heating controls which for me was a no-no.

Make sure, by the way, that the head unit you buy is designed for the UK market. We have different FM frequencies here (and likely DAB bands too) to the United States, for example, and it's quite likely imported radios will not work in the UK.

The built in speakers are not bad for a stock stereo to be honest, and a new head unit will drive them a bit louder too. If your budget stretches, you may want to consider upgrading the speakers But first things first.

You will probably need an ISO to DIN aerial adapter when you buy your head unit. That said, it's not clear if DAB reception is any good from the R170 aerial - others better qualified can maybe confirm - but for FM it's absolutely perfect. You may need to consider having to install a new aerial for DAB if you get poor reception.

For the microphone (Bluetooth and phones) there are a few guides to installing this at the top of the windsheild and the A-pillar cover is fairly easily removed to allow a neat run of cable to under the dash and to the back of the radio. I also took the opportunity to run USB power up to the tray / cup holder to simplify using a TomTom-type sat nav on the windscreen.

Silkie arrived with a cheap Pioneer head unit installed but I've since changed that for a Becker Indianapolis and again for a better-quality Pioneer head unit that integrates Bluetooth and FM. Took all of 20mins each swap.

The original Pioneer:

And the Becker (showing navigation):

Not got a picture of the new Pioneer but I can get one if you want.

In Australia, a shop called Soundlabs is now importing these Continental stereo head units with Orange illumination to match the SLK R170s, from Europe in three versions,

two with and without DAB but both have CD/USB/AU/AM/Fm / Bluetooth phone and music streaming. Reasonable prices too.

and another without the CD but with Bluetooth still

all look very appropriate for the period

Continental Bluetooth Stereo installed in R170

Here is the Continental CDD7418UB-OR installed.

This is the closest I have seen to getting a Bluetooth & DAB/CD/AM/FM/USB/AUX Stereo, (that is phone and music compatible) that looks like it could have been an OEM fitment, for a R170 SLK.

Its grey colour is pretty good match to the rest of the interior, at least no worse than the original Becker stereo.
The bling chrome rings on the volume and tuning knobs sort of mirror the highlights on the air-con and shifter.

The illumination colour is good match too.
Second photo is dimmer turned up full, headlights on. The brightness is actually pretty close to the other instruments and colour is too, even though this picture doesn't show it very well.
Third photo has instrument dimmer turned down low and you can see the Stereo also dims except for the central display. (somewhat of a disappointment )
Last photo is headlights off to show that the centre display stays illuminated the same amount any time the radio is on.

Other notes.
a) The power and ignition wires in the Mercedes harness plug did have to be swapped as per earlier posts.
I could not manage to extract the pin from the plug so ended up cutting the wires, soldering and heat-shrinking the joints.
b) The unit comes with everything.
External mic with two mounts (visor clip and adhesive type),
a good DAB antenna,
Harnesses for main plug with free ends and another for steering wheel controls (both not needed).
Stereo removal keys for the mount supplied.
Printed manual
Harness for AUX connections
c) you do have to source your own stereo removal keys for the OEM Becker unit fitted to SLKs to get it out. see eBay.
d) The SLK main harness plugs straight into the back of the unit and if it hadn't been for the need to swap two power wires, it would have been 100% plug and play
e) AM/FM antenna lead plugs straight in , no adapter required.

So how does it work?
Pretty good.
Manual is very brief, some of the important detail is hard too find when setting up. Read, re-read, re-read again
Pairing with my iPhone 4 was easy.
To accept incoming calls I still needed to use my phone.
Call clarity and mic both good.
To hang up, I did hit the red-"call end" button and it works.
Dialling can be a) "direct number input", easy. b) from "phone book" - not easy, seems the list is in random order, no A-Z scrolling c) from "last dialled" or "last received" - easy
Bluetooth music is fine but it does not display song title, just play time.
So it really doesn't do everything my SONY did, but it's ok.
If your phone is in a mount there is no problem. If your phone is in your pocket and you are trying to do everything on the stereo unit, calling out is quite difficult, at least with my old phone.
CD does not display track title. Just track number and elapsed time.
AM/FM/DAB. All good, lots and lots of preset stations to store. 2x6 AM, 3x6FM,1x6DAB, LW too.
USB was not reading either my iPhone4 or my 7 year old iPod Touch music libraries. Maybe newer Apple gear will work. I haven't tried yet.
USB says it charges at up to 500mA, but I couldn't get it charge either of my devices with leads that I knew worked on other units. Again I'll have to try an iPhone 6 and an Apple lead.
AUX -- haven't tried it. maybe I'll connect my iTouch to that for a store of music in the car.
Logic function allows it to be turned on and run with no key in the ignition for one hour. Useful
Mute, it's got a mute function that works in most modes and a Pause function for the CD
Preference setting is easy in set-up.
Prices: about 200 Euro. There is a much cheaper bluetooth unit without the CD but I don't think it looks as well integrated in the SLK.

Tip: to get the antenna and Mic leads through the dashboard, I used 10mm pvc tubing pushed from the stereo cavity out past the headlight switch/fusebox and it was a 2 minute job.
To feed it up to its final position I only had to take the drivers sun visor off, (not even the interior light or the main header trim panel).
Finding a good place for the mic, out of the way, offered few options and I ended up clipping it to the side of the Mirror base.

The phone holder in the first photo is a Brodie Proclip with a RAM mount screwed to it.
Not the most subtle mount, but it holds various sizes easily. (phone in its cover or iTouch) and it is removable in seconds.

Summary.
A SONY or Kenwood unit from a car accessory shop does all this for half the price, but doesn't look nearly as good, day or night.

Impressions after one week - CDD7418UB-OR

Impressions are good.
Function, design, illumination, look, readability, buttons, ease of use, - all good.

Phone book,
It is in alphabetical order of the SURNAME ! in the phone book,
which is not my preference, but now I know, I can live with it.
I can always copy favourite contacts and rename them
starting with "Aa" so as to be at the top of the list

Receiving Calls
I can't get it to pick up the call by pushing the green "accept call" button,
even when this auto connect function is set ON,
with either iPhone4 or 6. may be different if other countries.
So I have to 'pick-up' by touching the phone button.
Means I can't just leave the phone in my pocket. This is the main disappointment.

Making a call,
I can dial out using any of the options direct from the stereo.
Dialled/Received/Missed calls list only show numbers, not names from phonebook.
This may be a function of my phone however.

USB
It won't read my iPhone or iTouch via the USB input plug. Other blogs also confirm this.
The manual notes,
USB functions ( flash memory type)
(1) USB flash memory 2 in 1 support
(2) FAT 12/FAT 16/FAT 32 format supported.
(3) File name: 64 byte/dir name: 64 byte/tag name: 30 byte.
(4) Tag (id3 tag ver 2.0) - title/artist/album: 32 byte support.
(5) USB 1.1 support, USB 2.0 support (For 2.0,speed performance is as USB 1.1)
(6) Not all USB devices are compatible with the unit.
(7) USB connector is support maximum work power with 500 mA.
Other threads confirm the USB function is only for USB sticks.
So I need to convert all my Apple music files to MP3 and add to a USB flash memory stick,
I think I mayl resort to hooking up the AUX input to the iTouch.

Bluetooth music
I can get the music playing via the bluetooth, but one has to push Play/pause button each time after pushing source button to get to bluetooth source.

Max Volume
Max volume level varies a bit depending upon what function is being used, but it can only
be described as 'adequate' with the roof down for bluetooth music, but ok for other functions.
An amp may be desirable, but I am not going to bother. I does have wiring for Amp-On switching.

Manual / on-line help
The manual is brief, which is good when searching for general info in the car (how do I ...?) ,
but limited for technical troubleshooting.
On-line there is the same info, but I could find no extra details.
I found a VDO catalogue for Industry/OEM customers, dated 2013 that shows this model,
so we know it's 4 years old at least

Antenna
The manual doesn't say, but the antenna supplied in the box, for DAB is shown on other websites as "Passive".
(The setup required user to specify passive or active)
https://www.bergvillfx.com/index.php/products/car-audio/dab-antenna-passive.html
I took the mirror off, and fitted the DAB antenna unit high on the passenger side on the 'black-out' near the mirror
and ran the antenna 'arms' right up high out of sight and it worked fine

Overall
Much Much better than having the old OEM unit, functionality very good,
but doesn't do everything my SONY did for half the price.
Looks as if it was sold with the car from new. A really good aesthetic match.
Still the best original looking option at present in my opinion.

more info in RENNLIST thread here,
Installing The Continental TR7412UB-OR Radio - Rennlist Discussion Forums
It's a Porsche thread but has useful comments, see page 4. Page 1&2 are for Porsche installation.

Impressions of CCD7418UB-OR after two months

Very happy with the look, function, reception and quality.

Definitely needs an amp added to get more volume.
