camera detection

Hi people,
oh no, not another clueless newbe, just got me 2210 and tom tom 3, bit confused buy the camera detection , seen trafcam, so is that the way to go?, or is there a cheaper way? not that im a cheap skate or anything, but i dont want to spend a fortune to get software only to find out that i didnt need to,
read some where about downloading overlays with positions and then adding checkpoint? thanks

Download and install Checkpoint then go to http://www.pocketgps.co.uk/tomtompoi.php for finding the speed camera overlays etc.

Mine works fine and didn't cost anything.
