I tried the courses feaure on my Garmin 500 a few weeks ago. My conclusion, it does work properly, and from reading various Garmin forums on the issues, it has never worked correctly, and probably will never work correctly!
Summary of my issue:-
I saved one of my "fast" commutes as a Course, then on subsequent commutes I used the "Virtual Partner" to pace myself, at 100% course speed. The on-road results I got were truly bizarre. It started out ok, and I could see myself and the virtual partner tracking each other on the display. However, I found that if I stopped (for traffic lights, intersections etc), it would immediately stop working. After I started moving again, it woud show me a couple of minutes ahead of the virtual partner, and without any effort at all it would keep increasing so that half way through my ride it would show me ahead of the virtual partner by 10 minutes! Based on the course time, this was just laughable. It actually showed that I was 10 minutes ahead of the Virtual Partner when I only had 4 minutes remaining on the course time. So, in other words I should have finished the course 6 minutes previously.
Anyway, I then got a surprise because 2 minutes from the end of the course it still showd me 10 minutes ahead, but then a message popped up and said "Virtual Partner has finished the course". WT????
As far as I can tell, the firmware for the courses feature is riddled with bugs that Garmin have not bothered to fix. I have never been able to get it to work. The behaviour above is reproducable every time I use it.
