Hotmaps Classic Chip - display help

[Maasta]

I have a Lowrance 320C and recently picked up a Navionics Classic Chip for it (the only Nav chip it is compatible with). I cant find much documentation on the older classic chips & it doesnt seem to display much info. The display with the chip only shows contour lines. Give's you some "hot spot" markers and the lake outline is accurate. But no depth indicators on the map itself. Am I missing a setting in my GPS somwhere or does the chip only give you the outlines?

Might try calling Navionics. They are very helpful
