navigating a route relation with osmand

How can I turn a relation into a gpx with navigation instructions?

http://www.openstreetmap.org/relation/2834497

I tried to download the full xml and convert to gpx then put on my android and when I run it with osmand it turns a route of 12.8km into 400km+?
The route relation is perfect in osm I just need navigation instructions so I tried converting the xml into gpx with different programs but nothing works.

I need to follow the exact path of the bus routes.

I recommend to ask in the Osmand googlegroup forum:

https://groups.google.com/forum/#!forum/osmand

When I use http://ra.osmsurround.org/exportRelation/gpx?relationId=2834497 I get a GPX that looks fine on OsmAnd and navigation indicates its 12.8 km long

This is the same service that is offered, e.g. on https://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Walking_Routes#Antwerpen_2 to create the GPX tracks

I’m not sure though that OsmAnd can give the same type of spoken instructions for a GPX-file as it would compute a route itself.
