I have a 788ciHD unit. I have the western states chip

Customer Question

I have a 788ciHD unit. I have the western states chip for all the lakes. But the chip does not show contour lines of the lake. I am interested in a chip for Lake Almanor in Calif. How much are they? And do you just buy one lake at a time? Do I take the other chip out, or slide it in next to the other chip?

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.
I find no offered map for Lake Almanor, at least not in computerized or device-accessible form.
What provider gave you the western lakes map that you have on your 'chip' ?
Some providers offer contour lines underneath lakes as an extra feature. Perhaps your map's provider offers this feature.
Reportedly this map set does indeed have Lake Almanor:
