I was not satisfied with the hints given at the site kurviger.de for exporting tracks to a Garmin zumo.
I tried another way and it works!!
Here it is:
You need
a Android phone (Xiaomi Mi2 lite)
a micro USB-Adapter for exporting to a micro SD that you may use inside your Garmin zumo
All you have to do is:
make a Kurviger route
go to export
export route in gpx-format to the Micro SD of your Garmin
on your zumo go to tracks; import the file you saved to your micro SD
open the track
on the left upper side use the convert to route option
from start to end
give it a name
the zumo will produce a route
It is exactly the one you have made with kurviger.de
Go to Routenplanung
open the new route
Check it on the map
And begin with Start
Thanks for the explanation. We are happy to improve our current Garmin Zumo export description. Do you know if this works with different Zumos or is this something special of the 350LM?
With the difference that I export the track not the route. With the route export the result can be very different to my experience with kurviger and Garmin!
