My 15 yr old Sony camera quit working. A reman was going to cost $280. I got this setup with 2 cameras shipped from Costco for $220 (was on sale). You could get the 1 camera kit.
Backup Camera | RVS-770614 | Rear View Safety
Could not get the new 60 ft wiring inside the cap or wall, so I routed it along the outside back wall, then went under, along frame.
I used those black rubber/metal mounting clamps to keep it all in place. Looks pretty good.
I removed to old 'tube' style monitor that had hung from under the front overhead, and mounted the new 7" color one on the dash just left off the instrument cluster. Looks like a factory setup.
It was only $40 more $$ for that extra camera and 60 ft cable, so thats why I got that kit. If camera or cable ever craps out, I can replace in 30 minutes. Plus....I may decide to mount it on the door side for security reasons.
I like the microphone in the camera so spotter can tell me if I'm gonna hit somthing I can't see. I like leaving the camera on while driving.
