Re: Garmin BlueChart,,,,Downloadable??
AK- I have the GPSMAP 76CSx with the blue chart. The Lake Ontario chart included the St. Lawrence Seaway, and Oneida is on it as well. Also includes several of the Finger Lakes, but not all of them. You would have to buy the inland lakes, as JB pointed out. However, I do love the little unit- it has worked great in the boat and car, and I like that it uses batteries instead of all the cords. I recommend it, except the small screen size. Oh well. It appears that you will have to buy the CD, though. I haven't seen download only, although I have seen ads for the charts preloaded on the micro SD cards. That makes it easier, but if the chip fails, you lose your maps. Better to have them backed up on the computer.
