Installed a new rear view mirror / Bluetooth speakerphone /reverse camera.
Bought this and installed it yesterday. Took me about 45 minutes, still have to hide the power cord in the cab. Works just fine for me, I know it's not well reviewed. Spliced the power cables from the camera onto my backup bulb wires, and then ran the signal booster into the back of the cab. I'll post some pics later.
The rear view works fine as long as you give it a sec to turn on. Really helps see behind you. The Bluetooth works decently enough, a little tinny, but no static, no scratchiness, which is the best you can hope for for an aftermarket item.
Oh, and I got it for $99 Cdn on sale! I figured for that cheap, I could return it if I didn't like it.
