Review on Waterproof HD Image Wireless Backup Camera System, Supports Dual Cameras with Digital Wireless Signal, 5″ TFT-LCD HD Monitor - Perfect for SUVs, Vans, Trucks, Mini RVs, and Pickups (BOSCAM K7 Pro) by John Stowers

This is the 3rd Auto-Vox Backup Camera System I have owned: W7, Solar Wireless and now K7 Pro. I have different uses for each of them. None of my cars have a built-in backup camera system. I started with W7 (still using it on my 4Runner and pretty happy with it). Then came Solar Wireless (I put it in my tool box for when it sits in the back of my Toyota Tacoma and still use it today). I bought the K7 Pro because I heard about a major camera/monitor upgrade. That's really a big improvement. Everything on the monitor is crystal clear - almost like watching TV. Installation was as easy as it gets. If you're looking for a wireless backup system, any of these three are great. The W7 is a bit more economical, the Solar Wireless meets my portability needs, and the K7 Pro (slightly more expensive than the W7) with its excellent clarity. I would still give each of them 5 stars and the K7 gets a plus. Oh yes, I mentioned customer service - they get a 6 star rating.
