Hi guys I know this is quite a common problem but after searching and searching I am still non the wiser as there are so many different answers and methods.

I have an a4 2006 2tdi with concert stereo, I have purchased an aftermarket stereo to replace it but am struggling to get it functioning properly or even at all.

I have managed to get it powered up with a harness supplied with the new stereo but without sound to rear speakers.

I was advised to use the auto-leads pc9-401 harness but having purchased this and trying it out, I can not even get the stereo to power up.

If anyone can shed any light I would be more than grateful, thanks

 

i would check out crutchfield.com, im lookin to upgrade right now and am seeing that there are a lot of steps involved but they are very helpful. if you dont have bluetooth or ipod or disc changer it should be easier and they will have most of the adapters and **** you need and tell you what to do.

 

Thanks mate will have a look.
