have you updated to the newest firmware? it should be 5.xx. if not go to garmins site and download it. i could never get a lock with just running the older verison of XT. now all i need to do is fire up XT and less than a min i have a lock, no primer needed. as a side note when you up to 5.xx you can change the arrow to one of the pointers from the garmin garage. its pretty sweet.
