Just to update this thread MyRoute syncing between MyDrive Web App and IOS GO is now available. Works well. Thank you TomTom. However just need to get MyDrive IOS App to do the same. If you try to sync a route in MyDrive IOS App it does not work. So to get routes into Go App you have to either plan them within the app itself or MyDrive on a computer.
Progress but ..... would like to see MyDrive IOS app improve its functionality. Be able to sync routes and the all important to me import of GPX files. The only way to import a GPX file is by MYDrive Web App on a computer. Wish you could just do a direct GPX import into GO App like for instance you can with Beeline, Scenic 3 and Calimoto.
