I had some success with Live Search in my 8320 w/ T-Mobile and Freedom Mini GPS puck but I do get disconnection more often and had to start over again to get the new position with GPS receiver.

When that happen, the GPS tracking stop and kept getting this message. "Your current position is not available. Using last known position". Then I would have to go back to Home and select Options and select Configure GPS and select Disabled for GPS receiver and save the change then go back to enable Blackberry GPS and it shows a popup message saying " We will now initialize GPS with your new configuration". Then go back to Map and select Start GPS tracking and it will start to pick up the new position to begin tracking.

I'm having more success with Telenav using track me feature and Telenav would retry to pick up the new location when I'm in a weak network coverage to continue GPS tracking. Maybe Live Search need to do the same thing? Or is that related to 4.2 OS Bluetooth w/ GPS puck issue? Also I noticed that Telenav has GPS source option for Internal GPS or Bluetooth GPS. Is it possible to add that option for Live Search?

I really like the Live Search map much better than Blackberry Map and Telenav map. The point of interest information is very nice. It even shows Metro station in Washington, DC. Quite impressive.
