Difficult, as there are many possible entry points for RF ..... connect
the radio (leave it in the vehicle) to a remote battery or power supply
source via WELL SHIELDED supply leads and see if the interference is
Shielded DC leads must be used, as any airborne RF interference will be
induced into unshielded ones.
Another possible RF entry point is into speaker wiring ...
