Thanks Greg
I finally got everything installed and activated, And made my first map from sonar recordings. I need to make some more recordings for the lake. as I didnt have that much saved yet.
two things I noticed are:
1. that when you create your map and use a custom background map. the custom background dont show on the unit. it defaults back to the lakemaster default.
2. Also when you save a completed map in the .acd file it does not re-load as a completed map. you have to recreate it and re select backgrounds. at first all you see is a white checkerboard.
