Can any one tell me where the diversity switcher is located in a 2002 A4. Also where can i get on from so i can upgrade to a tv tuner for a RNS-E unit.

I don't know about your A4, but FWIW, the C5 A6 diversity switcher is below the rear parcel shelf, left of center.

In my A3 its located in the left side pocket in the boot. It has about 5 or 6 thin round black aerial cables connected into it.
