Pioneer AVH-X5500BHS in 2006 Silverado

A few questions for the experts on this forum. I have a 2006 Silverado with the Bose system. I purchased a Pioneer avh-x5500bhs and the gmos100 wiring kit through Crutchfield. I got the system wired up, but have a few issues that Crutchfield is going to take care of but I don't know if my other issues are part of the same problem.

My door chimes aren't working and the steering wheel controls aren't working. They said they will replace the gmos module and I shouldn't have to do anything with the wiring. They also told me that I could connect the factory XM module to this radio. They were right, but I have a small issue. When XM is on, I am supposed to get the information displayed on the DIC. This isn't working, so again, i believe this is the gmos module not functioning. Another issue with XM is the radio display. The Pioneer system has a 3.5mm jack for AUX and has RCA for AV-in. Crutchfield told me to connect the gmos100 AUX RCA jacks into the AV-in RCA jacks. This way I won't have to buy an RCA to 3.5mm adaptor. The problem is that the radio display keeps giving me the "driving while video is on" warning. Is there any way around this without using the video bypass? I may need to go purchase the RCA to 3.5mm adaptor.

I also need to figure out how to get HD radio working. There is a local station on 96.5 HD2 that I want to listen to, but the station numbers of 96.5 are giving the local talk radio and not the rock radio.

Sounds like they need to figure out what module you really need and stop fartin around.

Crutchfield replaced the GMOS100 module and I received it today. I hooked it up and before fitting the radio (very tight with all those wires) I tested the door chimes and steering wheel controls. I am happy to say that it worked. I buttoned everything up and tested the system again only to find out that the door chimes don't work again, the mute button doesn't work, the XM is supposed to display on the DIC and isn't, and I get a nasty hum only when XM is on. I did buy an adaptor to plug the XM RCA jacks into the 3.5mm stereo jack. XM sounds much better, but I still get the hum.

When I had XM connected to the AV jacks, I kept getting the "driving while video is on warning". I would also get that warning when I connected a USB to change the radio display. I decided to disconnect the light green wire that connects to the e-brake, and I rewired it not using the supplied wiring crimp. I can now change my background and I don't get that display pop up anymore. I'm thinking the GMOS100 is junk. Crutchfield has me trying a few things tonight to see if I can get it working correctly. If not, they will completely replace the wiring harness with something else. Unfortunately, I may lose my factory XM connection and rear seat entertainment with a replacement wiring harness.
