It could be a number of things.Originally Posted by Speed Junkie
Do your parking sensors etc work perfect just no sound?
Does your phone connect by bluetooth but just no sound?
If so its your amp. Our Logic 7 amp is in getting repaired at the moment and got the call to say everything working perfect now.
It could be one of the modules too but if everything is connecting as normal then mostly melt the amp.
Mick in Germanicks can do a test where he eliminates the issue module by module if you need to pin point the problem.
