my understanding is that they come with a pretty good mapping system built in
my issue is that my home lake does not exist on my unit been meaning to call them
but there hours are problematic for me my home lake is eagle mountain lake in tx
there is no out line is just show land i have updates to version 6.25
no help there hoping someone could clue me in on what i might be doing wrong
or if is the unit oh the lake is old impounded 1930's so its not like its a new lake
any help would be appreciated
