What kind of Navigational system is on the Genesis. Does it compare to some of the Garmin and other GPS systems out there. Can you do any updates on the system.
If the update comes in the form that is only able to be done at the dealer then it will be hard to find it on Ebay or the other internet venues. The GM updates come in the form of a DVD that you can purchase for $200.00 directly from GM. If you check the internet GM blogs you can find copies of the disc done with the various DVD cloning software for substantially less. I was able to update the GPS in my old Denali for $25.00 but the system was DVD based not hard drive based. Truth be, the GM update was not worth the money I paid, even the $25.00. Since the Genesis system is hard drive based at least in the Tech package, it may be considerably more involved to upgrade.
