Has anyone replaced their factory GPS receiver? I would like to replace mine but I have some questions. I have a 2007 Limited with factory JBL, GPS, and the rear DVD system. I don't use the factory GPS unit as I have a Garmin to show a more accurate speed and use an iPad with Gaia for off-road purposes. My intent would be to buy a single DIN deck, with integrated handsfree, and fill the remaining space with my DIN sized CB radio. I have a couple old school Phoenix Gold amplifiers I would likely install at the same time, so use of factory amps is not of concern. My main question would be, if I pull the factory deck, will I loose any/all function of my DVD system? (other than having to run audio to the new deck)

Has anyone with DVD switched to an aftermarket?

Thanks guys!
