This is about as easy as it gets. Link to your database account and allow auto update. My husband has used these speed camera alerts for a few years on his phone and satnav. So pleased it works on my Motorola Xoom.
Works well on the HTC Wildfire. I like it because it works, just using voice instructions with the screen off or with other apps in the foreground. It has a host of options to adjust for individual requirements.
