I bought a backup Camera on EBAY , It has a 3.5 in. screen. mounted screen on dash got power from Backup light circuit. I ran a 2 cond cable from the rear Camera/backup lights over the right rear fender well to the consoleup to the dash. The Camera was the hardest part, had to drill a hole above plate to the inside of trunk, filled with black RTV to seal any leaks. Seems to work fine has a good pic with graduated distance markers on the screen. comes on only in reverse gear, only cost $30.00. Which one to buy is your choice lots to choose from. did not see any bluetooth types.
