MOST of those ports are use or reserved for other shit...
Do this...

In BT settings-

Set GPS com port to: COM5

In GPS settings -
set program port to: COM3
and hardware port to: COM5 @ 115200

Hope that helps...

Also, google maps rocks, but you can either have directions or track your location, not at the same time, but you can switch back and forth instantly...
Id try Mapquest's app as that can do live tracking and turn by turn directions with VOICE... I have that on my old bb, dunno if there is a windows mobile
version, since i use tomtom...
