The CamerAlert database can be installed on many of the available SatNavs from leading manufacturers like TomTom, Garmin, Navman, Mio and more!
Excellent warning system with useful avg speed notification. I run it in background and have SatNNav running on the screen. Good customisation options.
I have used this app for about 12 months now. No complaints what so ever. I like being able to run copilot with it too.
