I bought this fishfinder/GPS thinking it would be a great combination, only to find the advertised map of "North America" did very little for us in the provinces of Alberta, Saskatchewan and Manitoba. The Map shows a total of about 4 lakes in an area containing 1,000's of lakes. Upon contacting Hummingbird they said they could not help me. I offered to send back the unused Fishfinder /no map GPS and pay the difference to move up to a model where you can then spend more money and get maps with better detail. hummingbird has been no help in doing this. No loss to them, more dollars in sales, but no deal. Customer service and satisfaction??????????????

It's very nice product, I'm very pleased with the combined GPS fishfinder (it makes my life easy). I would recommend it to everyone who likes fishing sailing.
