Hi,

You are correct, the grey coax is the antenna cable

The main radio amplifier is on the left hand side of the vehicle, on the C-pillar.

The radio amplifier is powered by a single (normally white) wire - this has 12V on it when the radio is switched on: eg: with ign in Pos1.

Otherwise you need to check antenna amp functionality either by disconnecting all the antennas, then connecting one by one - but this may not be easy.

Or changing the antenna amp with a known good unit.
