Hi All

I installed an aftermarket H/U into my A4 2.6 1998. The H/U was playing 100% - no problems.

However, after the car stood a while the battery went flat and where i would normally just put my code in with the Concert H/U the aftermarket unit is simply dead - assumption is the "car" is waiting for a code to feed power through to the radio.

How do i fix this?

Thanks in advance.

 

Unless your HU is one w/ anti theft it wont require a code. Check fuses first if that's not it then it will require further diagnostics.

 

Hey somebody5788 - thanks a ton for the reply. I checked fuses and all was well BUT - i noticed on the H/U when the face is tilted down there is a reset button and i pushed it, as people do LOL, and wahlah - it came in in about 2 seconds!
