One of the latest features of GarminConnect.com is the ability to plot a basic Course for your device.
Access is under the Course tab on the startup page. If you’ve a GarminConnect login you will see the green CreateCourse button on the top right hand corner of your local map.
The Course plotting functions are very basic compared to other route/course planning sites. There is no facility to add Waypoints or Coursepoints so in use you will not get any warnings at junctions.
If your a Garmin Edge 800 user you also need to turn on the OffCourse warning other wise there is no warning if you go off Course.
In use your pretty much stuck on the map page as the only alert you are going to receive is when you go off Course. That is despite enabling CoursePoints on the Edge 800 Course settings page (the wrench or spanner icon).
I’m a bit disappointed at the end of the day as Garmin have had a long time to get it right, this is what they do as a business. It’s a work in progress and at the moment the other web based Course planning sites have nothing to fear.
