I have an early model year 21 Tahoe RST with the rear infotainment screens mounted to the back of the two front seats. Not mounted in the seat back but on a bracket behind the headrest. Both screens have been damaged and I never really wanted them in the first place! The car was ordered off the train from the factory in late 20. Dealer advisor says they can’t be removed because they are integral to the sound and navigation system. Has anyone else had these removed or replaced? Any suggestions would be appreciated.
