Does what it says on the tin works great on my HTC Desire and with copilot live I get directions and speedcam warnings. Was worth subscribing to as twice this week it warned me of mobile vans so I slowed down and round the corner was the the nasty yellow van man, I smiled as I drove past at 29 mph!

What can I say, BRILLIANT! Warns of all mobile and fixed cameras including average speed cameras, is very accurate and will work in conjunction with an iPhone navigation app. Weekly database updates are prompted as you launch the app on the iPhone and downloading new data is quick and efficient over WiFi or 3G.
