Hey, I've just bought a used golf mk IV 1.9 TDI.

In that car there's a standard volkswagen radio with CD-changer and Casette player. Now I've found out that this particular car already has an standard amplifier built-in.

Yesterday I tried to put in my "old" radio with USB ports, mp3 capability, etc... but the plugs that go in the back will not fit.

So i went to a car-parts store and they told me that there are NO linkage pieces to connect my system to my "old" radio. Does anyone else have had this problem? Can you please help me because i want to listen to my mp3 CD's and not some stupid old normal CD's.

Waiting for a helping hand be4 i get homicidal on my radio
