Anybody using this unit?
Plus, I'm not sure if my 08 Sierra Denali has the centerpoint system....checked the VIN without any luck from numerous sources.
Important Note: Rosen'* GM0710 navigation receiver works with GM Bose sound systems (except the Bose Centerpoint system), while Rosen'* GM0720 receiver was designed specifically for the Centerpoint system. Unfortunately, GM'* dealers and code sites tell us there'* no reliable way to identify the relatively rare Centerpoint system. If you install the GM0710 and your system doesn't work, we will express ship the GM0720 receiver to you at no extra cost. The cables and harnesses are all the same, so you can just pop the new stereo in and send the unused cables back with the old unit.
