Just got a 2013 durango r/t and wanted a 430n and a backup cam but dealer could not find one with other options I wanted so I settled. Using iphone 4 for nav but wanted a bigger screen. Paired iphone w/pad for nav but still no backup cam and cabin is looking really cluttered. Is there a way to feed my iphone map to 430 monitor and maybe a bluetooth cam too for backup. I'm too cheap to pay 2 grand+.
