Hi,

I will suggest you reset your GPS, to reset your gps, follow this steps, turn off your device. Press down on bottom right corner of the touchscreen, and then power on the GPS unit. You should be prompted whether do you really want to erase all user data, or asked if do you really want to start up in maintenance mode. Press Yes to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.
Once the GPS unit is reset, remember to place the device outside where there is a clear unobstructed view of the sky for 15 to 30 minutes in order for it to requires fix to GPS satellites. with this, the abnormalities should be fixed.

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.
