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!
Works perfectly and seamlessly on my Samsung Galaxy S2. Very useful. The autostart feature works brilliantly. Would like it to start completely invisibly but it does start as process in foreground, not a problem as can dismiss it with a press of the back key.
