Im thinking of getting one of those lcd rear view mirrors with back up cameras. They have a lcd so i assume it can recieve signals from a device. I was wondering waht would be the cheapest way to hook up a gps to this screen? Like one of those in car navigations would that be possible? Whats the best solution for this? I want to keep my headunit so i didnt not want to buy the eclipse avn. Are there a touchscreen rear view mirror out there yet? thanks

 

I havent seen a touch screen rear view yet.. I have one that has two av inputs...I use one for the rear camera and i have a seperate feed fromn another dvd player... hidden in the small compartment in the dash.I havent got the nav signal to work yet....I had to split the signal on the rear view camera.....to get it to work

 

At this time, why not just use a portable GPS unit? That's what I use. I just attach the GPS with the suction cup holder to the windshield and off I go!
