20 Most Recent Lowrance Endura Sierra Handheld GPS Receiver Questions & Answers

Hello there:
here is what you can try to do is first unplug any power going to the unit and remove the battery these units have a internal reset device that will reset it'self after a given amount of time which is about 1 hour.
during this time press in on the power button for 2 minutes and if it has a reset button it press in on this for 2 min leave the battery and the power out of the unit for the rest of the remaining time i had mentioned.
now plug in the power cord back in it and start the unit now if it works ok simply turn off and replace the battery and you are now done ok
Hope this is very helpful for you
Best regards Michael

Greetings, Please consider returning the device to the manufacturer and purchasing a Garmin GPS from amazon, BestBuy, or Walmart. Garmin has been around for at least 1 decade and I believe has a more solid brand name than Lowrance. Thank you.

Hi, Please test the backup sd card on another GPS if possible to see if the zoomed-in section of the map file shows up or not. If it shows, then you'd need to send in your lowrance gps for repair from the water damage. Thank you.
