K6-BT and two serial cables, one for CAI-302 and one for ClearNav
vario. $220 value and I'll sell for $125 with free shipping in the
USA. Simply connect the K6BT to your device's serial output and pair
the K6BT with your Android. It probably works with Apple products, but
I can't swear to that. Do the research.

Since I put in the PowerFLARM portable (I know, hell froze over), I
replaced the K6BT with a K6-BT-Mux so I could connect both the PF and
the CnV to my Streak/XCSoar.
