Audi Repair: 2002 Audi A4 radio, antenna,, radio antenna, blown fuse

Question
My radio now receives zero AM stations and only one or two FM stations.  Otherwise the radio seems to be ok, so I thought it must be an antenna conection problem.  There is no external antenna, (I guess its in the windshield.)  I can't find a mechanic with experience with this problem.

Answer
There is an amplifier for the antenna, check the fuses to see if there is a blown fuse in any position, also check the physical connection to the radio, and are all the cables connected since one of the cables powers the amplifier for the antenna.  Is it an OEM radio?  Most radio installer shops should be able to help you out.  Let me know,  Jan
