I have been driving a Peugeot 508 for 2 years in which an integrated TomTom navigation; (also connected as it is called) Works great to navigate to a destination. I wonder if there is no App. would exist with which I can also proceed to load GPS routes (.gps files) via the USB port, such as the many "Roadtrips that you find or create yourself. I am looking badly but cannot see the forest for the trees.
I would like some advice. With thanks
