Radio Amp

[talljames]

ok, next update. Turns out my second bm53 radio module is bad (luck of the draw when your buying off ebay). Sent my bm53 radio module off for repair/upgrade. While waiting for its return I put the other bad one back. In the mean time my maps on the screen disappeared and i had a basic menu system. The yellow light would come on when i pressed the power button but obviously no radio. Then the whole head unit went dead. Received the fixed bm53 radio module and installed. Turned the engine on and I had full volume radio but no controls at the head unit to turn the volume down. Still no head unit activity and I notice the cd equipment in the boot does not have a red light on. A little stumped at the moment. I did try the removing of 7, 72 & 73 fuses and the disconnecting of battery with no luck.
