You have a number of options if you want to change your route - 1. Backtrack 2. Reverse your route 3. Create a route on your unit I have not done the first of these in any of our videos (as they are not really supposed to be tutorials, but show you 'what a unit can do') and the our 'online resource' the online training platform takes you through how to actually do everything - gpsonlinecourse.co.uk/ BUT, on my 'walk and talk' with the 66i not everything goes to plan and i do the last two of what i have listed above - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-d-pHLX7u5gs.htmlsi=ZRIksxCg3Exmexzf&t=776 I hope this helps.
