About seven years ago, I purchased a Garmin 60CSx Gps. At the time, I was going through the ACMG Ski Guide Program and needed a reliable GPS unit. Since I wanted to add maps to the handheld unit, I acquired the Garmin MapSource Canada Topo series.
The combination worked great until I left the Windows XP operating system behind and moved on to Vista and now Windows 7. Since that time, I have not been able to sync my GPS unit to the MapSource software - which is to say that I have not been able to upload maps / routes to the device or download routes / waypoints to the software. Once I left XP, the MapSource was not able to detect my GPS when it was plugged in, and the main error message would be "The Serial Port Com 1 Does Not Exist." Needless to say, this has been extremely frustrating and I have spent way too much time trolling the Internet for a solution.
Minus twenty degree Celsius may not be great for rock climbing, but it is good for toiling away indoors.
So here's the quick fix to link your Garmin 60CSx GPS to your MapSource software (procedure for uploading map to the device):
1) Turn GPS on and connect to computer with supplied usb cable.
2) Go to Main Menu page
3) Go to Setup
4) Go to Interface
5) Click on USB Mass Storage
6) Open MapSource Software and highlight whatever segment of the map you want to save.
7) Click on the down arrow to the right of the download to GPS icon.
8) Click on Storage Card Reader
9) Click Save
10) Don't forget to properly eject the device when done
I hope this helps!
