I am trying to locate a Pre-programmed Data Card for a Garmin GPSMAP 172C. I sail on Lake Ontario but understand the original data cards covered all of the Great Lakes. This generation of Garmin's in no longer supported and maps are no longer available. I was hoping to find someone who has upgraded to a newer generation unit but hasn't tossed the old data card for this area. Thanks.

Hi Mike,
Funny you should post. I'm buying 392 (sent deposit yesterday and will close as soon as seller finds title) I think it has a garmin chartplottoer on it with great lakes card. I use my ipad and iphone with a handheld for back up so have no need for it.
My email is seamarc@aol.com and it should be at SBYC soon.
