"Rarely Works, If Ever"1.0 starson by michael_mcclellan
Pros: Small, long battery life
Cons: Not accurate. Pairing/Satellite Problems
Summary: This device was purchased to go with the blackberry worldphone. It was paired with the device successfully and worked on a few occasions. However, most of the time the device would take over 15 minutes to link up with the satellite. By that time I had already stopped to ask for directions. Cusotmer service (TeleNav) was almost non-existent. However, I will say that they were amicable to refunding me the entire purchase amount after the entire ordeal.
