In recent days, Garmin International received a couple of user reports of
GPS III Pilot and GPSMAP 195 portable navigators which seem to lock up when
users entered a VOR or waypoint name starting with the letters X, Y or Z.
Turns out this glitch was triggered by the introduction of some new
intersections in the latest Jeppesen database update. On April 24, Garmin
released a free operating software update that corrects the problem.
