I bought this unit used and installed it without any problems. On the first trip out after about 20 minutes of running fine the screen suddenly went erratic and the depth read .07 and sonar was useless. Gps was fine and responded fine. The erratic sonar continued as I tried to isolate the interferrance. (i assume this is my problem) It continued as everything was turned off and no motor running. Huh...still acting crazy. My next thought is the gps puck might be too close to the unit. It is about 3 feet away on the top of the gunwale and the unit is in an electronics locker (tiller rig). The unit will operate normally for awhile then act up again. I'm guessing it is something electrical that is causing this. Anyone have suggestions or has this happened to anyone else? Everything has its own fuse as well as ground and wires are as far apart as I can get them.
