Loc: Central Texas
At Lake Fork and bought the boat lane chip and installed it. Works great but I lost all my contour lines. What did I do wrong and if nothing how do I take the new info off? Have a 899 si di unit if that helps.
I have a hummingbird 997. Installed boat lanes. How many trails do you get. Mine said I did not have enough memory for all trails I got all the major lanes and the one lane on the west side by lake fork marina. Am I missing anything ,tried many time to call them and got on reply
