Sorry for leaving out the details. Yes, it's an '05 Yukon Denali with premium Bose, XM with traffic module, Pioneer back-up camera, BT2000, steering wheel control module and On-Star.
I'm not a car or car radio enthusiast. I'm just someone who want's the best of everything in his truck and that's what Tweeter and others said I was getting.
Thanks for your feedback though. At least I know the installer isn't BS-ing me.
