My NSC BT CF card works like a charm (discovered both my T68i and my Motorola Headset within seconds), except for one little detail:
THE STUPID DRIVERS CAUSE THE AXIM TO DEVELOP HICKUPS !!!!!
By "hickups" I mean momentarily the Axim freezes (for about 1-2ms), then continues, then freezes again, and on and on and on.......
So now I have the BT card out, and I use it only when I need to.....
