Question about Lowrance LMS-332C GPS Receiver
Had same problem with lms337. i had upgraded the unit but had not upgraded the lms2000 gps module. i was turning the isolator on in the boat which powers up gps module, if the lms337 is not powered up as well the gps unit goes to sleep. the upgrade fixes it by checking that the unit has not been turned on periodically. otherwise as soon as you power up gps module also turn on lms337. lowrance product support sorted this for me.

Had the same problem with another model. Cable from the antenna had a broken wire where it plugged into the head unit. Intermittent problems can be a pain. Try moving the cable when the unit indicates a failure. It wont fix it but might point out the fault. Mike
