Mine is a 320, obviously I havent tested it in the field yet since i just changed it tonight, but I went to look back over todays track and it had already changed to color of the track on the map. Will test it out tomorrow in the field to make sure it is still doing right.
here is a step by step of what I did from what Cutterbay told me.
Go to the main menu, go to tools, go to track manager, go to dog tracks, select the dog from the list, go to set color, select what color you want then hit the back button.
Hope this helps.
i will try that,,, thanks
