Well I thought this would be a great place to ask this. I have an 06 2500 that has a bose system in it. After doing some research I put a non-lux NAV system in 15229287. The original head unit showed my RSE and XM just fine. This Nav unit when I tried to power it up only displayed the clock in the lower right hand corner for 10 seconds just like you were pushing the recall button when the ignition is off. So I checked the connection in the back and found 12V on B1(Orange wire). The data bus I believe is on A1 below it. The only way I can get this TNR to power up is by putting a jumper wire from B1 to B2 the empty socket then evertything works just fine. Except the radio won't see the factory XM or see my RSE. I also thought the NAV should be locked seeing it came out of a H2 but when it does power up the DELPHI screen comes up and then the normal radio screen. Am I missing a wire on my harness or just doing something wrong here?
