How to manage waypoints and import export them in nuvi and from BC here:
Code:Please Login or Register to see the linksYou can send waypoints created in BC to your nuvi. Note that BC does this by sending a file named temp.gpx to your nuvi. This is merged into your favourites when you switch on the nuvi. Once the data you've sent has been merged be sure to delete temp.gpx ... otherwise you will never be able to delete the data contained in it from your nuvi, as it will be re-imported every time you switch it on.Spoiler: source
