This happens when the device detects a map that cannot be validated for use with your device. I work a lot on GPS systems for marine captains and I see this quite often on Garmin when they have downloaded outside map data or the existing data has been corrupted. You can try the steps on Garmin to restore your original map data. https://support.garmin.com/en-US/?faq=3QHdSDE3Q80Vd3EHFN11u7 Cheers!! Monte
