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!
I have tried others but this is the best. I had a recent problem when I upgraded to a new iPhone and sent an email to support. Within a very short period of time they responded and solved the problem – superb customer service. Highly recommend this app.
