Not worth it - extremely cheap build. I bought one a year ago or so ago (saw it at a Walmart and was tempted) and installed it on my 2009 JSW. It took some effort to pull out all the trim and route the power wires properly (you still need to get the 12V that goes on with the reverse light) and I was quite proud of my handiwork - you cannot tell that there is a wire in there!
It worked for a while but even at its best it would pick up a fair amount of interference and I'd get streaking white lines across the screen. After about 3 months or so, the monitor quit working on it's own! I still have the camera mounted and it is probably still sending some signal when I put the car into reverse (unless it quit working as well)... but I will never know for the screen is blank!
As PlaneJob suggests, I wish I'd also sent a wire for the video feed when I did the original install. The marginal effort wouldn't have been all that much and I would have had the option of fitting a proper wired system now. As it stands, I will need to rip the trim again and I am reluctant to do that. So I've finally decided to junk the camera and use the 12V line to power a strong led based backup light that I can mount onto my license frame. Probably one of these summer weekends ...
Don't waste your time with this - it's junk.
