I have had this Garmin for about a year now. I used it ice fishing and open water and one day when I powered it on, it took me through options to set up the unit as if it were new. After I set it up it no maps would appear. Since then every time I restart it, it takes me through the same setup steps. Any idea what this may be or if there is a fix?

Time to give Garmin techs a call!
