I have used previously the TYRE software and managed to create routes and upload to my TomTom rider 400 successfully.
I have now upgraded to the Myroute app and paid for lifetime membership.
I can create a route successfully but, it will not allow my to export from my Mac to the TomTom device as safari will not recognise any support connector tool. I have also tried to transfer the the downloaded route as an ITN or a GPX file direct to the micro SD card, but once the SD card is placed in the Tom-tom device it recognises that there are new routes but will not import them at all.
Can you help please
