I have been fixing the sound and nav system in my car due to water damage . I bought a used Mk3 computer and a new radio unit . I hooked up everything, and all works normal , exept i don`t have any sound . Suddenly a couple of days later , i turned up the volume and there was sound . I was happy . But then two mornings after no sound one again..

The radio unit I bought was a different part no. than the other , do I need coding or is my amp dead .. Umounted the amp today , I have tested that the amp has power , and it was warm .

Any ideas ? Jochen ??? heheheh
