Sending routes to Zumo

 

This question may or may not apply here but the other Zumo board I visit told me how to send route to my GPS and I know how to do that..

My question is which is better practice.

I have 4 routes created for a 3 day trip. Is it better to create 1 gpx file with 4 routes in a gpx file or is it better to create 4 gpx files with 1 route each to send/copy to my Zumo saving the file(s) on my SD card?

.

It doesn't matter. It's the same thing.
