We are new to the world of GPS and are contemplating our first boat
purchase. The used boat we are considering has Garmin GPSMap 220. Since
this is a discontinued product, I'm assuming the existing G Chart cartridges
are so old as to not be very reliable. Can someone please confirm?
According to their website, Garmin's offshore G-charts have not been updated
since October of 2001.

Thanks -
