See this website for detailed instructions on how to install and use the app: http://www.mybiketraffic.com/help/

*IMPORTANT* To work with the new Rearvue 820 Radar ... YOU MUST CHANGE THE DEFAULT CONNECTION MODE SETTINGS using the ConnectIQ mobile app. You also must make sure those settings sync across before you add the datafield on one of your data screens.  *IMPORTANT*  

*TLDR* If you have any of the other radars prior to the Rearvue 820, power on your radar BEFORE you power on your Garmin. This solves most connection problems. This is particularly important if you have your connection mode set to "Switch between 820 and older radars". *TLDR*

*NOTE*  Finally, for people newer to Connect IQ data fields who are not aware how it works - you must install the data field AND manually add it to one of your data screens in order for ride data to be recorded during your ride. *NOTE*

See how many vehicles passed you in a ride. Plus upload your .FIT file after the ride to see exactly where each car passed you. NEW: enable auto-sync through Garmin Connect. You can still manually upload rides to mybiketraffic.com, but you can also enable auto-sync to see the locations and speed data for where cars passed you.
