Dealer quoted $700 to run wire for backup cam, Need Advise

Thanks for all the advise. I went with the RVS wireless system and hooked it into the factory Screen on my Ram dashboard. The camera is routed to the transmitter hidden in the AC shroud. As others have mentioned in motion the image stutters but for me I only want it when backing up and it works just fine. Mounted the cam to the back and taped over the wire with a generic eternabond type tape.
