That might be a little difficult. Sort of like trying to tell you what to do with your smart phone or personal computer. Just get good at what you know it does and explore features as you get more comfortable with it. Ask in the
Electronics, Lighting, & Gadgets sub-forum if you need help with your new found feature.
Group tracking is one of the more interesting to me features that Garmin's now do. You can see where others of your group are and send messages. It was slightly useful recently when I rode ahead of my group and then I stopped for a nature break and to chat with some others at a rest stop. Then when ready to ride again, I could see how far ahead my friends were since they didn't have to stop and pee.
