I believe this is the same one (or same manufacturer) sold at Canadian Tire. I picked this up at Costco for $99 or something like that.
Piece of crap.
Screen is really too small to be any use. Lots of wireless interference. In fact, one time driving through a neighbourhood, I pick up p0rn! No joke. Hardcore p0rn. If I could get that whenever I wanted, then it'd be worth the money, but otherwise it's a waste.
The picture is designed to come on when my reverse lights are activated (wired to the lights). Most of the times it works, sometimes it doesn't. Not sure if it's a bad connection at the lights or this is the way it is.
I guess it meets my basic needs though. I have a long narrow driveway and usually back in all the way into the garage. I have this fear of backing over my kids, so this was meant to reduce the big rear blindspot.
Unless you absolutely need it, don't buy it. The WUD just saved yourself $114 big ones. You're welcome.
