I installed the HotMaps Paltinum chip in my HB898 and it will not show contour lines less than 6FT. How do you get the Lake Pictures ,Satellite photo overlay,3-Dimensional view to work. The Lake Palestine Texas map does not show any contour lines in the bays and north end of the lake. It only says timber and distance to the dam. I only fish in Flat creek area so this is a BIG disappointment. The paper HotMAPS show the contours for all the lake Palestine areas.
