I'm new to this forum but have some experience with tomtom products. I have owned the 700, 910, and now 920T models. I'm still trying to figure out how the free traffic service works that is included in the 920T product. It seems like the service is extremely limited in the US and has better coverage in europe (which doesn't help me). If there is some one who is using the TMC/RDS service successfully please let me know!
