I am about to replace the delta head unit with an aftermarket CD player unit in my 1997 A4. Does anyone know if their is a unit out there that will keep the radio station showing in the instrument panel?

Also need to know what wiring harness I should get from Metra. They have a basic harness and a harness for an oem radio. Which one should I get?

The third question is about the antenna adapter. My antenna is within the glass of the back window (not on the roof). Is there a special adapter for this type of antenna?

Thanks for your help.

 

you might need a euro adapter for the antena no I doubt theres another radio that will show up in the instrament panel (will just be blank)
