connecting pioneer head unit to slk 230

[ian prescott]

Hi, I have just fitted a pioneer head unit which works fine except the FM
radio has poor reception. I have read the instructions and believe now that
the aerial booster is not connected to a power supply.
There is a blue/white cable attached to the booster and I have a blue/white
cable (which is not currently connected together as supplied with the HU)
would this supply the required output to the booster? Any help or advise would be much appeciated
Many Thanks
Ian

Hi now fixed, the booster box requires the 12v feed which comes from the blue and white cable (remote control lead).
Perfect reception now on all channels.

SLK 230 - Fitting a Kenwood Head Unit

I am picking up on a previous thread to do with fitting a Pioneer unit. My guess is that the wiring issues are similar if not the same. Hence, my question is as follows:

My car is a R170 (1999) and I have simply connected the ISO lead supplied with a Kenwood unit to the OEM ISO connector in the car's wiring harness. It all works and the Kenwood does all the 'tricks' that it is supposed to . However, the radio reception is ok but not 'brilliant'.

In the same way as the author of the 'Pioneer' thread identified, I do have an unconnected 'blue and white' lead at the back of the radio, labelled 'Power control/ Motor antenna
control wire (Blue/White) - Connect either to the power control
terminal when using the optional
power amplifier, or to the antenna control terminal in the vehicle"

I didn't worry about attaching it to anything because I haven't got an 'electric aerial' ........or have I?

I have seen comments on here about the on-board amplifier which is located in the boot (N/S). It hadn't ocurred to me that it needs a power source but from reading the other posts, this seems to be the case and the 'blue and white lead - from the radio - is (maybe?) the source.

So, should I be looking for an ISO lead adapter sort of thing? I have searched eBay but all those seem to be for post 2004 (R171s) OR can anyone tell me what colour lead should I look for that runs into the back of the ISO 'plug socket' on the wiring loom - to which I can connect the trailing 'blue and white lead' from the radio.

I hope that this make some sort of sense and that I am not barking up the wrong tree.......as it were.

Many thanks

Hi,
As far as I believed the aeriel signal amplifier has nothing to do with the stereo wiring and has a separatetly sourced supply. Though you have made me think now as I have had similar issues with mine, though mine is slightly different, it has worked, and since taking it out to fit a Parrot kit the radio reception is a lot poorer, it might be worth checking the aeriel lead where it plugs into the stereo as apparently they can suffer from cable breakage there ie, the thin centre conductor of the aeriel cable can snap where it terminates in the plug, I have suspected the cable on mine and have since bought a new cable from MB (circa £10) cheapest solution, then if this failled to cure it I would be looking at new aeriel amplifier, but maybe this amplifier is supplied from the head unit, so I think it might be worth checking to see if I have a voltage on this amplifier first, with the stereo on.
Has anyone else know where this amp gets its power from? does it indeed require a supply from the stereo, and somehow this has been inadvertantly disconnected.

Snooper HU

Hi Ian,

Great post, just fitted Snoopers dvd/sat nav head unit very sim to your Pinoneer (not as nice though) and have suffered the same issues, as soon as the rain clears I will be out taking a close look. I have a spare power ant cable from my head unit, do you think this will be connect to the blue and white lead on the cars multi pin plug.

Fitting A Pioneer Stereo To an SLK 230

Hi Guys,

I realise this thread has been dead for a while but I found it very useful so I thought I'd firstly post my thanks and secondly add my experiences.

I've just fitted a Pioneer DEH-P4100SD to a 1998 (R170) SLK 230 and my initial problems occured removing the factory fitted head unit. It seeems that the right hand latch had 'Moved' and didnt line up with the removal slot so I had to break away enough of the surrounding plastic so the removal tool was presssing against the latch and not below it. The damage isn't huge and hidden once the removable part of the face plate is replaced. Just in case I ever want to reuse it.

The Stereo didnt require any wiring loom adapters, the included wiring just plugged in, although an aerial adapter was required. Sliding the unit back in was greatly helped by removing the footwell kick plate so I could guide in the multi connector and ensure the aerial stayed connected.

Somewhat expectedly the Radio reception was rubbish, so appling the knowledge from this post I pulled the unit out again to look for blue/white wires. Sat there looking at me are 2 both fitted with bullet connectors one from the multi connector going to the loom and one from the head unit labelled remote control. Connected them together and the radio reception is perfect.

So thanks guys for all your help, and for ease of fitting, general good looks and features I'd recomend this head unit.

Regards

I am having similar problems on my latest W124 E220. Everything works fine except the RDS feature does not always seem to work. The radio is a Sony with bluetooth hands free and streaming facility.
I will go and look for a blue and white wire lying loose somewhere

Loose Blue/White wires

Hi

Just to be clear about my 'Loose' Blue/white wires, there were both on the Pioneer supplied wiring.

I assume they were originally intended for different uses, Remote Control, but they worked great for me by connecting them together. I'm pretty sure the Blue/white wire from my stereo connects through the multiway connector to a blue/white wire on the MB side of the connector so if Sony haven't supplied a convenient wire you'll need to find a stereo switched power and somehow get the power through to the MB side of the connector.

Good Luck

Graham

I think me and you have the same sony unit(very bright blue at night) let me know how you get on. I have a problem with only being able to get a maximum of 3 out of the 4 speakers working. Electrics arent my cup of tea! Ive been told it might be to do with the w124 having a speak balance switch?.
Anyway very usefull thread, and if you do get any joy getting your rds sorted id be interested to hear how.

I have trouble with the rear speakers but I never have anyone in the rear anyway so it doesn't matter. Is yours a Sony MEX-BT2700?

Re: Fitting A Pioneer Stereo To an SLK 230

This may be a bit of a dumb question, but does an SLK (230K, 2001) have a built-in power amplifier? I seem to recall seeing conflicting messages. I'm considering replacing the stereo in my car, and there is a super nice Pioneer unit (DEX-P99RS http://www.pioneer.eu/uk/products/25/121/61/DEX-P99RS/specs.html) that I am considering -- but I think it only has line level outputs, i.e. no amp built-in.
