There's no magic trick to fix your problem that I'm aware of, poor GPS sensitivity is a common complaint here. The first Moment I received had hideous GPS performance until the GPS stopped working altogether. The replacement works much better but I've found the gps sensitivity of the Moment to be lacking when compared to previous HTC phones I've owned and my wife's Pre. It will work fine on the open road with no obstructions around but bog down when on local streets with trees and large buildings. I don't have to reboot to get it to work though. I've never used an Instinct, but there is a "speak it" function in Sprint Nav. If your phone isn't updated to cl14, doing so will greatly improve GPS performance in Google Maps, but it won't effect Sprint Nav. It's also possible that 2.1 will improve the GPS on this phone with better drivers and Google turn by turn, but we won't know until it's released or a beta tester breaks his/her NDA. If your GPS issue is real bad, you might want to take a trip to the Sprint store and see if a replacement unit works better for you. Good luck!
