I just want to be able to put my track for the days sailing on a website so it will show all the details as in max speed etc. How do I do that on my Colorado 300?

Is it sufficient to just turn it on or do I have to do more? I do not need it for navigation, except maybe distance back to base, so I know how far I have gone.

can you do anything with it at the moment?

can you get the data you want to show on your computer screen?

have you read the, gulp, manual?

I am able to get access to the GPX files and I have tried to put them on the site http://www.gpsvisualizer.com/map_input but I have no luck in getting track along with the speeds etc. to show.

I know it can be done.

try loading 1 of your gpx files to another site like
mapmy tracks

do you use any of the garmin software for opening the gpx files?

mapsource etc?
