I purchased a boat in Mass. and obtained a Garmin 180 GPS with it. I sold the 180 but have the chip. It is a Garmin G-chart Cape Cod to Montauk. #s MGUS182SL. ($299 new) $150 . anybody interested? email

Not to bust your bubble but I bought that same chip off of e-bay for $ 40.00. If there are no takers here you might want to try selling on ebay, good luck!
