Folks,

I REALLY need some help here please!!! I have read and re-read every post on this forum about hooking up an MP3 fly-lead to my 06 4x4 HeadUnit. I eventually came to the conclusion that it was a poverty-spec job, which didn't play MP3s and didn't have ANY audio inputs on the YELLOW connector plug at the back. So in desperation I bought an MP3-compatible unit from Italian eBay....

Which looked to be exactly what I wanted. It has the MP3 logo on it, it has a fully pinned socket bay for the yellow plug, it has the correct pin-out label on the back showing the AUX facility for A.AF-L, A.AF-R and A.AF-ground. All great. Pic below.

I bought the yellow plug cable off the Net (I also have the blue one too as it happens) and hooked it all up yesterday, via the yellow plug. All fitted perfectly and I thought I was nearly there...

The Good news is that I can now play MP3s on CD - it reads files, directories and has al the correct MP3 options in the MENU section as expected.

BUT - it still won't play from my MP3 play over the fly-lead due to the fact that I cannot get AUX selected on the Head Unit. I can press the CD button as many times as I want, but nothing doing. If I'm in RADIO and and I press CD - then I get CD. Press it again and nothing else. If there's no CD in the HU, then I get a message NO SOURCE AVAILABLE, which would make sense.

One of the chaps in the office has a 100HP and his CD button trips between CD, CDC and AUX when we press it repeatedly.

Can anyone please tell me what you have to do to these pox-ridden units to get AUX to work !!?!?!? :bang:

I really don't want to buy an aftermarket HU - I just want to find what needs to happen to get AUX to work.

Thanks,

Phil G

Have you tried the Aux lead on your colleagues unit. Normally the Aux in is the Blue plug and the yellow for output. On Aftermarket Blaupunkt units the yellow plug is for RCA's and the OE units have the space for it but it isnt connected to anything.

I also have the blue plug version of the 3.5mm Jack/fly-lead and although I just tried my new 3-wired blue plug into the slot on its own (ie without the original block of blue/green/yellow connected at all), I still got nothing.

But, if there's a chance that by replacing OEM blue with my blue 3-wire/MP3 lead, whilst still using the OEM green/yellow pair to make up the full set, then this is a combination I've not tried yet. Still surprised I can't switch to AUX by a double push on the CD button, but perhaps that's normal if there's no AUX source available.

I assume that I have no need to try to reconnect the other wires from the OEM blue connector (Data-Out, Data-In, UB+, GND and Switch) ?

Will pull it out again tonight and try. Many Thanks for the response though.

Thanks,

Phil

Will the aux source be available in the menu even if nothing is connected, if not is there a way of making it show up as I cant get it, just get cd then radio then cd again. I have connected the wires up in the places shown on the back of the headunit.

Are you using the blue or yellow plug.

neither i made up my own but conected to the last 3 pins, middle being ground. Is that correct?
