It's not 15 seconds, but neither are most GPS units. Also, once I have a lock, I have it. It constantly updates as I'm driving/walking. The major glitches are: as you mentioned, I get NO GPS inside (even with VZ Nav running); around tall buildings, the GPS accuracy drops way off and I have hard time initiating a lock around tall buildings. These scenarios don't seem to fit with VZ blocking the GPS. Especially since on my Pre Plus I could get lock inside if I launched VZ Nav first. On the Pre 2, I get nothing inside, w/ or w/o VZ Nav.
If you read the article it explains how you can really only get locks inside based on aGPS from tower triangulation. So the fact that you and I can get no lock period inside indicates that aGPS is disabled.
On the Pre Plus opening Verizon Navigator unlocked aGPS and then it worked inside. Your experiences fit perfectly with the problem being aGPS and Verizon actually making the problem worse in 2.0 by not turning aGPS on when Navigator is opened. Fortunately Palm has improved the basic GPS chip, and it seems to work well outside.
