I have a Lowrance in dash mounted model # LMS-332. My problem is three things, first the unit itself will come on by itself rather the boat is being used or just sitting in the garage, I can turn it back off and it will still continually come back on over and over again. Second, the GPS will not acquire its position so I am not able to use the mapping part of the unit. Third the sonar does not work consistantly, for the most part it does'nt work. Now if I only had one of these problems I could believe it was a wiring or other issue, but with all these it seems to be a unit problem. Has anyone else ever seen any of these problems? I have had the unit out of the dash and all connections are good and the wiring looks good as well, the boats only an 06 model. The only way I can keep the unit turned off is to pull the fuse for the electronics. I am going to call Lowrance today and see if i can send the unit to them and get this taken caree of.
