Report "soft reset machine and no matter what it wont lock onto satellites even though it sees several satellites. This unit has been in desk for 18 months or so and was working fine at that time. Then needed to use it and repalced batteries with new and it refuses to lock onto satllites. Unit has never been dropped or mistreadte in any way. The thing appears to be an expensive bot anchor. I am reading where others are experiencing exact same issues yet see nowhere that Lowrance is providing a solution. Firmware is already at lateset version. So my advice is dont buy anything GPS from Lowrance as they are not supporting their products"
