I have a 60cx, and when moving it does take a bit longer to get lock than when standing still. I’ve never had it not get lock, but have heard of others having issues.
here’s a trick to try. From the satellite screen if you click menu and select new location you get the option of automatic or use map. if you select use map you can tell the unit where you are, I guess this must tell it what satellites to look for overhead.
What unit software are you running? The most current is 3.50/chipset 2.90. you can check your version of unit software here: main menu, setup, system, hit menu and select software version.
I believe garmin would tell you to reset the unit, it’s a special key combo and resets it to the factory defaults. I can’t remember the key combo of the top of my head, but I’m sure someone else can chime in.
