lms 339?

[fish2live]

i want to set it up as a portible gps so i can bring it with on buddies boats and have my lake master chip. when i only hook up power and no transducer it goes into demo mode. does anyone know how to do this?

You should be able to just change the pages to the GPS map screen and it should work. Is it a 334 not a 339? The 339 doesn't make sense to me I don't recognize that as a model number of theirs. Does it have an enternal antenna for gps. That would be the 334 then. The 330 and 332 needs the receiver.

it's a 339 same as the 334 but, with duel freq transducer. this is a warrenty replacement for my 334. yes it is internal antenna. i did that last time i tried it, but that doesn't mean i didn't do something wrong. i will give it a try
