I have a 2004 SS indy edition. everything is stock. I have factory XM radio. I recently installed the non-lux tnr800 nav radio. The radio was built as a 2004 Trailblazer. Everyting on the radio works as it should except the xm band. The digital radio was setup successfully under the tech 2. When the radio is on i do not get my XM band. When I check for fault codes w/ the tech 2 under the "digital radio" I get a U1000 class 2 communication malfunction. So evidently the xm tuner and the nav radio are not communicating? Anyone have any ideas?
I do have unlimited access to a tech 2 tool.
