I work at Best Buy also....United Grey GTI...How interesting, LOL. I already have the Garmin 2720 so I opted to go wothout the nav. I also have a indash Kenwood I plan on putting in the GTI, as soon as I find a dash kit for less than $40. Does anyone know what Sats the GTI nav uses? Garmin uses the military Sats which are the best for acurracy. By the way you wont be bale to watch movies going down the road with the Pioneer....it has a gyroscope built into the brain that knows when you are moving.
