Re: Navigator for 9800
Depends on what you mean by "navigator". If you mean voice and auto reroute, there aren't any free ones. Did you read the sticky at the top of the GPS & Map section that has reviews of amny of the map apps?
All require a BB data plan.
IMHO, if you want navigation, the best option is a standalone GPS device, not a cell phone. More features, usually can be updated easily and doesn't require a cell signal to work.
