Its the first time I try to use this. I have a GT-31 unit. I opened the data in GPS results. I tried the "upload to GPS Speedsurfer" button but despite loading the page it came up with the words "no data". I then tried to save the data as a GPX file and uplaod it. That looked like it worked, but again came up with the "no data" message.

Any advice woudl be great.

Thanks

Please make sure you have set your username and password in the program GPSResults. The username password combination set in GPSResults must be the same as used on this website.

have fun

Good to see you on here John and posting some speeds, you'll find you'll get the speedsailing bug though and keep chasing faster and faster speeds 

Yeah good to see you on here John.

Thanks guys. turned out i had not written the username correctly.

Enjoying the speed, but a bit embarrasing posting my speeds in between the Luderitz posse!
