Helix 7/Lakemaster Problem
I recently bought a Humminbird Helix 7/DI GPS Combo, along with a Lakemaster Southeast States Map Card, version 3. Okatibbee is listed as a high definition survey. My unit will display the map of Okatibbee but only when zoomed out. If I try to zoom in or move the cursor to another part of the lake, the screen goes white with a small message in the corner saying loading chart. This happens at home while in simulator mode as well as while sitting on the lake. While on the phone with Humminbird, they hooked up a Helix 7, inserted the Lakemaster card and had the same problems. Also, while in simulator mode, I looked at Grenada Lake and everything worked fine. EZ tried loading Okatibbee on his Helix 10 and after about a minute it loaded. It's in the hands of Humminbird so we'll see what's done.
