SCONASOTAN Posted September 20, 2007 Share Posted September 20, 2007 I have an older Lowrance 3300mt gps and I was wondering if and where I can get it updated to be able to utilize the newer lakemaster and navionics mapping chips.thanks Link to comment Share on other sites More sharing options...
LMITOUT Posted September 20, 2007 Share Posted September 20, 2007 Go to the Lowrance HSOforum and then go to the downloads section. You should see all the units listed with available updates. Link to comment Share on other sites More sharing options...
