Back when I first got Autochart Pro, 1st edition, you could transfer waypoints via google earth. Just had to make sure both were using the same gps format. Once the points are on google earth, convert and transfer to your autochart pc program. I don't remember the specifics, but once I figured out both needed to be the same gps format, everything went smoothly. You can also find stuff on google earth, mark it, and transfer those point to your sonar unit. Then go check them out while on teh water. Saves a ton of time exploring new water.
