Will Nav Upgrade Work with Factory a Harness?

[Furyous]

I have a opportunity to buy a factory nav unit that I planned to replace my non- nav Bose in my 2007 escalade. It does not come with a harness, but will the existing harness work? I can't imagine GM making different wiring harnesses for different sound systems.

I have done this upgrade it will work with no issues as long as it is also a bose nav. Try to find out if the numbers match your vehicle and year they changed the radio harness in 2010. You may have to go to the dealer to get the radio unlocked other then that its all plug and play. If you plan on using the navigation you will need to run the vss wire and gps antenna.

I just litterally got done installing mine on an 07 Tahoe non bose and I had to but the vss sensor, none bose kit and gps.
