I use Smartlink to transfer from MRA to my Zumo 396. From time to time I need to repeat the process. But it still beats using a USB cable. The 590 should work too.

@Lars-Jensen said in Garmin Zumo 396:

Before you open the route in Programs->Route Planning go first to Settings->Navigation->Calculation Mode. Select Faster Time and save.
Now when you load the route it is recalculated and the straight lines should be converted to follow the fastest time roads.
Repeat when transferring another route

If you trust PC’s or Macs then transfer using USB. Then just follow the rest of my instructions:

Just a pity that it took more than 3 years to get this far. I had a subscription for three years and during that period it always crashes when I used it

I am using a 396 and as you I saw straight lines when transfering a route from MRA.
Here is a work-around that I use. Try it - maybe you can use it.

Transfer the route using either USB or as I do with my phone using MRA and the Garmin Smartphone link.
In MRA: Open the route and hit the button Page menu -> Save as .gpx 1.1 (BETA route, track, POI)
Select SEND TO ZUMO in Smartphone Link and if you’re lucky the route is transferred to the 396.

Before you open the route in Programs->Route Planning go first to Settings->Navigation->Calculation Mode. Select Faster Time and save.

Now when you load the route it is recalculated and the straight lines should be converted to follow the fastest time roads.

Repeat when transferring another route
