I'm just wondering what cellphone, service provider and plan you are using to get it to work.

I picked up a TomTom ONE and would like to get the traffic data, but it doesn't work w/ my current phone/service provider (sprint). I thought i would ask here before I try and go nowhere asking T-mobile/cingular/tomtom tech support.

 

I have a guy at my friend that uses his with Verizon i believe. He really likes it, except he said it was sometimes difficult to use while driving because he has to squint.

 

There is a Garmin Nuvi Travel Assistant GPS with bluetooth that provides an FM traffic update so you don't have to pay for a traffic updating service. Probably not as good as paid, but better than nothing and it isn't fee based.
