TA-t3, Not all programs that need BT will turn it on. My Navicore doesn't. When I select "Activate GPS" from the menu, it won't turn on BT to find my GPS. I have to do that manually. I wish the BT icon were persistent, whether or not BT was actually on (different icon for off vs. on), with the ability to turn BT on from the icon's menu, just the way you can turn it off from the icon's menu.
