I think I was told at one point, no you cannot integrate the factory XM system with an aftermarket HU, but I honestly don't know. I just installed the GM Navigation HU and was looking to install the XM components.
Hmmmm, best as I can guess, that's built into the main dash harness. It's customized at the factory to accommodate things like the digital versus manual HVAC system.
To make it easier for the dealers to install XM< they might have left the part you need in. Can't tell. Recommend just looking behind the glove box where it's mounted and see if you have a spare dangling connector. Otherwise you have to buy the connectors, do the pinout research, and fabricate one.
AFAIK, they're just plug, PAY, and play. Since they can be deactivated by XM within minutes, there doesn't seem to be a market for stolen units. My wife had her exposed GPS swiped, but the removable XM SkiFi next to it in a cradle was untouched.
Thanks for the quick reply. That is what I would have figured, but I have seen a lot of conflicting information on other forums. Hopefully after installing the unit and activating it no further action will be required.
Hello everyone. Well I'm new here having just bought a 08 TB on Sunday. Actually it's my wife's and she graciousley allows me to drive it once in a while!! Anyway it did not come with XM and she really wants her XM back. We would like to have it with OEM GM parts so I am looking for the correct part numbers for this vehicle. Can anyone supply the numbers? Thanks in advance for any responses.
GM has a kit available that included all the necessary cables, antenna and receiver. For a 2008 TrailBlazer the part number should be 17801145. I will look when I get home for the individual part numbers if you need those.
