Hey guys I bought an 01 s4 from an auction,tape(casette) plays good,but I dont get radio reception.
It just makes that noise like the antenna is not plugged in.I looked inthe trunk and in the lower left I found a few electrical plugs(like 3-4).On two of them the cable looks like is from the antenna.Whats missing? A picture would be great too.
Thanks!
Adrian

 

The diversity antenna modules for your car should be under the rear decklid panel. Its possible those are the connectors for them.
