You can't use GPRS/phone traffic with the TTV3 as it does not have bluetooth. Be wary though, if you have a TTV3, as when you connect to the PC and TT Home, it will offer you the option to pay for TT Traffic - a service which is not available for your device. I queried TT about and they say that everyone gets offered it irrespective of whether your device supports it which seems a bit sneaky. Similarly, the recent upgrade to the main program gives a couple of new buttons which are useless as they are for functions not supported. I have reverted to the previous version of the software. Overall, TT is a good product with good nav (mostly) but unfortunately poor customer care in my experience.
