Sorry for the delay; school has been keeping me busy. I appreciate the replies.
So I have a 550t on the way, and I've checked out several dozens of types of mapping software...and now I'm scared
Is there a good step-by-step tutorial on how to make vector maps? One thing I would like to be able to do is take a satellite image from Google Earth (or other electronic map), plot a route/add waypoints, then load that onto the GPSr. Most of the info I've seen so far is focused on the exact opposite: uploading your already-traveled routes onto Earth. I'm willing to purchase the necessary software, I'm just not sure what I need.
Again, thank you for all your assistance. Hopefully my ears will dry quickly once I get some hands-on time
Peace,
Taiko-ma
