i'm using Garmin Mobile XT sat nav and it connects to my GPS via the native GPS Intermediate Driver (GPSID), which is MS's native driver that exists on WM 6.0 devices. with this configuration, i'm getting locks on 7+ sattelites in 45 seconds or less. basically, no GPS priming is required.

when i change Garmin Mobile XT to use COM4, it takes a loooooooooong time to find the port and connect, and in most cases, it will automatically revert to the GPSID and connect almost instantly. i've tried MioMap 3.2 and iGO 2006+ with the COM4 configuration and it also takes a loooong time to get sattelite locks and peformance is not as good compared to Garmin. I've found priming is a must when using GPS with COM4. when i am able to connect GPS via COM4 in Garmin, i can launch iGO/MioMap and they connect almost instantly.

Questions: what port the GPSID is using? is it the one assigned from the GPS option in Settings->System Tab? and, how many of the existing sat nav apps can communicate using the GPSID? i'm stumped as to why some of us are having good results and others are not.
