Back-up camera

[hmrlvr]

I installed a wireless back-up camera. Works great, just the cheap $129.00 from pep boys. The camera hooks to the reverse lights and the monitor plugs in to the accessory outlet. PROBLEM: the keyless entry won't work if I leave the monitor on when I get out of the truck. However, it works fine if my cell phone is plugged in to the other accessory outlet and the monitor is on. Ideas? (besides "turn the monitor off")
