Hi
I have dowloaded my GPS information to Toutatech. Now I would like
to upload this info to another GPS (also Lowrance Global Map100).
I have transferred the waypoints(675) no problem. My next step is to transfer routes (11) or tracks(2).
After either routes or tracks has been transfered two problems occur.
(1) All of the free waypoints become used with points from the route
(causing duplicate waypoints & incapable of saving new waypoints)
(2) the waypoints no longer are displayed on a plotter scren on the GPS
This problem seems to cause permanent damage to the GPS, and after
all info has been deleted and reloaded it will no longer display waypoints.
I have talked to Lowrance about the unit , but they are not aware of any
problem with the GPS.
Any Suggestions?
