I can recommend the Tom Tom Go. The speed camera data base is a downloadable add on, along with points of interest etc. and is as good as the Geodesy I used to have. No radar though of course on the TT. There is a free camera database most people use at
www.pocketgps.co.uk, updated monthly by info from users. Also available is one TT sell for £50.
Bonus is you get a GPS nav system as well!
