This is my first post so please be patient
Having just purchased my SLK 280 Uk rhd, i wanted to upgrade the head unit, a friend has successfully done this on his clk, so i have read all the posts i can find but it was all a bit confusing so i thought give it a go.
So my car has a comand ngt 2.5 i think , the mercedes number is bz9860 a171 900 12 00 80
I purchased a Kenwood DMX 7017DABS head unit
Connects2 CTKMB07 Complete Head Unit Replacement Kit
so now to the issues
1). i cannot find a permanent live anywhere, looking at the posts here i thought i could pull it from the AGW unit, but i dont think i have one, i have looked in the passenger footwell but its empty.
I got the switched live from the cigarette lighter socket, but i cant find a permanent live anywhere
2). I wired the permanent live to the switched live so i could test the unit.
Hey presto it all seemed to work... but
No AM/FM radio , i guess its a powered Ariel , i have an Ariel power out on the kenwood but where does it go ??
3). The MFD display appears to not work at all, the information is there but MPG, Miles travelled etc., never update.
im guessing that its something to do with the MOST ring, the original head unit had these connections, but the supplied leads from connects 2 unit just blank these off in the iso converter. can i get these functions back or are they issued from the original head unit? is it possible to link the in and out MOST? its not a deal breaker but MPG and travel time info would be nice, i know the satnav and audio MFD displays wont work, but thought the other screens would be ok.
4). Cannot get the steering wheel functions to work, i connected the can bus unit supplied by Connects2 , cut the short wires and left on connectes , and connected the Kenwood steering wheel control wire blue/yellow to Key 1 as advised but nothing, no up/down volume .
Hope someone can advise, sorry if its a repeat but i did look at the previous posts,
Many thanks in advance
