It's probably not a good thing that the Windows Mobile 5.0 Bluetooth configuration UI for my Bluetooth GPS receiver has made me feel stupid, but I kept trying to get the damn thing to work after installing the A06 ROM upgrade. It worked once, surely the setup steps I did then was so obvious that I'd remember.

Bzzzzt.

After failing over and over to get the BT GPS signal to connect, I finally gave up and, imagine, went to the manufacturer's site for configuration documentation (what shipped wasn't for WM5.0). Bluetooth GPS setup on the Windows Mobile 5.0 OS . One ba-da-bing later all was working and the light on the receiver went from a mocking flashing state to a conquered steady state.

Now I can start getting serious about GPS fun.
