i have a 07 Z71 Tahoe and i have the dvd rear package and bose system but no navigation. I was wondering if i can clip on a screen and installthe GPSsoftware to the console? or do i have to go threw the dealer? ( kinda hoping it clips on...lol) and the only reason i ask is becasue the dealer sells the Navi. for about 2500.00 and on ebay i saw it for 1500.00 brand new with the software.


new to the forums thx for the help
