An idea for the future as it would make managing the GPS unit far easier.
In TYRE, the function exists to both 'Copy To' and 'Delete From' the GPS unit. In MyRoute-app web, I can only 'Export' a route to my GPS (via the connector) but I cannot delete any existing routes from it. This means I must do it manually from the GPS unit itself which takes time.
I think the same also applies to POIs and favourites but I'm not sure. I do know that TYRE has much better GPS management though.
Okay, thanks for the tip.
