I just bought it off eBay trusting it to be a working unit. I'm 100% certain I wired the unit correctly. I used to be electronics engineer and now software engineer. You can verify my wiring in the link in my earlier message
When I get to the "Current Config" menu it lists all of the devices except the telephone on the first page. The second page is listing"(0xFFFFFFFF) which I think is this fried unit.
When I reconfigure for my factory installed Motorola system the (0xFFFFFFFF) device is no longer listed and my phone is listed on the first screen
