I bought a 2007 Chevy Suburban LTZ. The truck has the optional Factory Navagation with Bose stereo and optional Bose premium speaker system.
Per Navigation System 2007 owners manual page 64 Quote "If the system has the Bose sound system, the system will have Digital Signal Processing."
The DSP allows four different listing settings. Normal, Surround (for DVD), Rear or Driver.
Well I have the Bose system but my unit does not allow or even have the touch screen icons for the DSP settings.
The Temecula dealer states I am right the option does not come up on my unit and says there is nothing they can or will do. How is it that I have all the needed uprade options per my window sticker and per the owners manual but and DSP is not available. Does anyone else have the same problem?
Call Chevy's 800 #. Maybe they can authorize a swap of the unit to make it work.
