i have a 76 csx. easy to use, have eastern hot spots loaded, 12V cigarette adapter to plug into the truck or boat. Map installed on laptop, can transfer to and from the unit. Only thing it doesnt do is microwave popcorn for me.
You wont be sorry with any Garmin you buy. Tons of accessories, user freindly. a little more than other brands but to me it has been worth it.
