2010 LTZ DVD does not read

[Barry Vaughn]

I just purchased a 2010 Tahoe LTZ with the Bose system and RES. Currently the head unit gives fail to read error. Bought laser cleaning disc and didn't change.
Two questions: 1. is there a fix that someone knows of? 2. If I replace the head unit, who has one with Nav. and also keeps the RES in the system?

I don’t know about a fix, but you’ll want to get that Maestro iDataLink stuff to retain all the factory things (like your RSE) if you go with an aftermarket HU. The one on the left is to keep RSE.
