TBT not working. Off course and Course Found notifications do work. I have TBT set to On for the course I'm using. When I select a course and press Go I don't always get the Calculating % message. Turning the unit off and on again can cure this but surely this isn't right. GPX course routes are created on Strava and/or Garmin Connect.
Software version 2.7
GPS Software version 2.86
Have tried a reset, pressed top left hand side of screen while powering on and chose reset from the screen that came up. No difference.
Grateful for any help you can give on this.
Richard
