Lowrance GPS - Popular Questions, Answers, Tips & Manuals

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.

Sounds like the memory card you can not recognize is faulty or corrupted.

Not sure about these but try holding the on / off button in for about 30 seconds. The TOMTOM resets when you do this, maybe the 3500 does the same?

I suggest contact your dealer to purchase the correct connector.
