Trying to sync the G-metrix with on screen action.
For timing and lap count purposes I need to start G-metrix at a particular point on track.
When trying to set the 'Activity Start' The track location 'dot' starts moving well before actual motion and when the designated 'Start' line is reached the 'dot' is approximately 1/2 Mile in advance of the actual position. When pressing the 'Done' button I get the 'Lap Data could not be detected'.
I don't understand what is taking place!
