Computer guru can it be done

[lroberts]

I dont know about cell phones, but you can get gps readings, what you do with them afterwards is beyond my comprehension. I have an eagle sonar gps unit, but lost the book. It took me a year to figure out what my grandson did on his last trip, now I can see my baits sometimes. there was a tutorial on the web, but forgot how to access it. My hand held gpsgot soaked and quit.If you want to borrow my navionics dvd its just a call away.

Can you download this DVD onto more than one computer????
