Thread: VW Golf V Aux Adaptor - help!

Hi all,

I don't think the answer to this is already here. I used to have a Seat Ibiza with a stock Grundig head unit. I bought a cheap Aux adaptor to give me a 3.5mm jack input, and everything just worked - when I pressed the CD button (I think it was labelled that - it was about 6 years ago!) the stereo showed AUX and everything was hunkydorey.

I've bought a similar adaptor for my Golf Mk 5 with a standard single CD head unit. The cable just has the basic 3 wires: L, R and earth. The connector was wrong so I've wired it to the back of the stereo myself.

I've simply connected the L to CD-L, the R to CD-R and the earth to CD-earth (simple eh?) - I would expect by some miracle that this would just work.

However, everytime I press the 'CD' button, my stereo trys to play the CD in the slot and never goes to an 'AUX' mode. Is there something else I need to connect? I've searched and searched and searched but can't find anything useful.

I urgently need help - this is my first step in the carputer I've been planning for (literally) 8 years.

Cheers,

Bob
