Tracks into Routes

Navigator / SP III, anyone know how to convert a track into a route and how do you display a track on the GPS.
I can upload and display tracks on the PC but can't for the life of me work out how to save it as a route, Copy & Paste won't do it.

When viewing the track on the PC there is an option to display on GPS, so I download the track but can't figure out how to display it on the GPS.

Any ideas ???

Jimb,
Suggest you follow us all up to Dutchman's place in Edinburgh this weekend for the GPS Technical meet when, hopefully, all will be revealed
