The radio could be a failing antenna聽 Quote Link to comment Share on other sites More sharing options...

Definitely sounds a wiring issue then. Might be worth removing the trim in the boot to inspect the wires 1 Quote Link to comment Share on other sites More sharing options...

Can only assume it was done when the back window was tinted. 1 Quote Link to comment Share on other sites More sharing options...

Magnet Posted November 23, 2022 Share Posted November 23, 2022 What is the history of the car James, that may explain the disconnections?聽 Kind regards, Gareth.聽 Quote Link to comment Share on other sites More sharing options...
