lowerance map

i have a LCX-17M fishfinder. does anyone have a mapping card for this unit they aren't using? the unit is about 2 years old. it has blue plugs, if that matters. the mapping is a feature i have never used, but the unit has it. its a feature that might be worth having, but i don't want to spend $150 on a map card.

i don't like pudding. or any sweets for that matter. anyway, i am willing to buy a used one, just not a new one. i guess i really don't even know what the mapping feature does?
