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.
I have been using this for over a year now and find it to be spot on. Having just changed phones I emailed CamerAlert in the evening to change my details and the following morning it had been done. An excellent product with excellent back up.
