Hi all
So had a radio failure and it was the BM54 so replaced it.All good for a week but now the Sat nav is not working, No power light so can anyone tell me if it is powered from the radio am or if it is a separate power feed.
fuse is ok so I want to test for power so need to know which plug /pin if that makes sense.
Any way to test the unit itself.
This is the old style unit not touch screen.
Cheers

If you've got the TV tuner unit you can plug its Blue connector into the Satnav Blue socket. they are interchangeable. If it powers up then that gives you some idea of where the fault might be? I don't know which connector provides the power but you could check in Rave. If it's via the White connector this probably won't help.
