My Better lap on Saturday.
Using the Garmin VIRB and Dashware software to put the data GPX files together.
There is a small sync error between the GPS location/position and its speed/Acceleration and Braking that I can not fix but there is an update due.
Have a look at Dashware - only found it when trying to fix the sync problem in the VIRB free software - which is good but the sync tools and data logging in Dashware for £30 is fantastic.
Film using any camera and log your position with any other or same device - phones can be used and sync together - fantastic!
