+Thutmosis Posted July 10, 2022 Share Posted July 10, 2022 PN-60 just quit working. I installed the latest firmware which restored most functionality, except a screen pops up " Demo mode is unavailable. Update firmware to reinstall Demo mode" But I just reinstalled the firmware and I don't want the demo mode. I can't close the screen. No matter what I do, the msg pops every 10 seconds. My GPSr is nearly unusable. Quote Link to comment
+Capt. Bob Posted July 15, 2022 Share Posted July 15, 2022 Have you tried a NVM re-boot? If you have done so and still have a problem your unit may need reformatting. Quote Link to comment
+Capt. Bob Posted July 16, 2022 Share Posted July 16, 2022 Non-Volatile Memory (NVM) is a storage area that retains your data when you shut down the GPSr. It contains data regarding your last location, ephemeris, almanac and other format settings. The procedures are described here: https://support.garmin.com/en-US/?faq=4ErqMmVofk9TVOOnvCfpMA Quote Link to comment
