I would opt for the GPSR traffic option via cellphone if my phone and service were supported. I have a Motorola Q via Verizon which is CDMA and will not work with the traffic service via bluetooth. I can't win LOL
I have a Verizon TreoWX, and it works.
Make sure your phone has bluetooth, internet service, and supports DUN (dial-up-networking)
Turn bluetooth settings on your phone on, and make phone discoverable
On TT, go to menu and select "Tom Tom Traffic"
It will ask you to set up wireless data connection, select yes.
Next, before setting up wireless data connection, follow the prompts to set up the bluetooth link between your phone and your TT. Starting here, lasting through the entire process, keep an eye on your phone as it will prompt you for a password (0000). It will prompt you to do so multiple times, if you fail to do so within a minute or so, the set-up attempt will fail, and you'll have to start over.
After that is complete, it will attempt to set up the wireless data connection choose to set it up manually.
access point name: vzw3g
Username: mobile#@vzw3g.com (mobile# is your cell phone #)
Password: vzw
Dialup #: #777
DHCP: "auto"
DNS: "auto"
logon script: leave it blank
If this doesn't work, turn off both devices, then try again. Took me a couple times to establish link.
Also, in the "dial-up#" field, TT places a default *99 there
once you have set it up, then try to do at least a weather update, just to make sure you are connected. Once you are connected you can try to up date traffic. If it fails, then call customer support at Tom Tom, 866-486-6866. They can re-set your user name and password so you will be able to log on. This is were I had to go because i was getting the old your subscription has expired message. When I called them they re-set the account. It is still free at least until November as far as I know.
