I have been using the 8800's GPS feature alot because it (the 8800) is a new toy to me. ;^)
Quickly I noticed that I prefer Google Maps ('GM') because of the ability to switch to and from satellite view and its superior ability with finding places and routing direction. Plus I am comfortable with it from using it on my old 7100t.
I have noticed that GM has GPS signal issues (no position info) unless I first start BBMaps. After probably 15 minutes, Google Maps will lose GPS signal or position info. I have to swap back into BBMaps and stop then start the GPS, get back into GM and it immediately and without problems has position info again.
It makes me think that there is a powersave feature that cuts off the GPS circuits after a certain period of time, possible related to if BBMaps is on screen. In any event, there is only two ways I know to interact with the GPS circuitry: BBMaps 'start/stop GPS' and the Options\GPS Settings\UpdateInfo.
*Attn developers:* It would be nice to have software on the 8800 to manage more parameters of the GPS, mark waypoints/POI, and see tracks/paths/elevation data... Just like the BIM training log software available through RoadRunnerSports for other GPS phones
