Please, don't take this personal, I beg of you, please.
I wish I could offer assistance and tell you exactly what to do, but I can't see waisting your time fooling around with it. Even if you do get it to operate, it will disappoint you in the end.
The Concercrap in my precious TT worked great. No problems what so ever. Until, one night, while watching a good movie, one side of the sound took a dump. The dealer replaced it and all went well. I sold the TT and the Concercrap did the same with the new owner. "How disappointing", he said. He bought a replacement on Ebay and so far, it works great(until it decides to take another dump).
I recently bought a fifth wheel. It had a very nice Concercrap unit with the satellite radio attached. It works great. Great sound, great picture. But, I can't see going through a disappointing camping trip, so I removed it, prior to a catastrophic failure, to install a name brand Phillis unit.
I now have a rectangular piece of plastic to throw on the campfire if I run out of fire wood.
We now return you to your regularly scheduled program.
