Guys I have just replaced my stream stereo with a Stream MP3 stereo I purchased off e-bay. The stereo works absolutely fine on radio and the Cd in the stereo, however what i have noticed is the sound quality when i play a cd from the changer in the boot is very poor and when changing cd's it seems a lot noisier. Anyone know why this would be? does the cd changer need reprogramming to work with the new stereo or something?

Common question

The ground pin needs to be swapped over - I did exactly the same head unit swap.

It's as easy as taking on of the power pins out and sticking it in a different place.

Have a look at Stu's site for details:

Thanks Timmyboy i think you've hit the nail on the head, and thanks to stu for the in-depth procedure

Will try this as soon as i get a minute spare

Done it this morning moved the cd earth pin into the next one along and hey presto perfect sound again from the cd changer
