I have a TomTom 720 - but don't subscribe the their speed cameras - they are crap!
Just buy a subscription to the
PocketGPSWord cameras - they are updated every month...in fact - they were updated just yesterday!
Go for a TomTom, it does have it's quirks but nothing major if you are just planning a route a to b etc...
Good luck with the TMC - come on over to
YourNav if you have any issues - I'm a moderator over there...
/Plug mode off! :-)
