using SD card with Garmin Etrex

I have a Garmin Etrex. It comes with a 4 Gb memory but the supplied mapping takes up almost all of this. I would like to be able to create multiple routes on Cycletravel, load them onto the Garmin and then access them.
I've bought a 16 Gb SD card and installed it in the battery compartment as per the instructions. The problem is that if I plug the Garmin into a PC I see the Garmin (F-drive) but the SD card is a separate entity (G- drive). If I load tracks onto the SD card and then try to view them using 'Track manager' on the Garmin I can only see the ones in Garmin Etrex/Garmin/GPS not the ones on the SD card.
Does anyone know how to access routes on an SD through the Etrex unit?

Are you putting it in the gpx folder on the SD card?

The card is new and had no folders on it.

I created a folder saying GPX and put the routes in there, no joy.
I then put this folder in a folder called Garmin and there they were in Track Manager.

Many thanks

These pages are a good source of info for all things Etrex.

I have found tha entire folder structure from the unit needs to be replicated on the SD card. This usually starts with a Garmin folder at the top level and there may be intermediate subfolders before you get to the gpx folder (I don't have one to check the details).

Also, I used to use an Edge 605 & found with that there was a limit to how many routes it would index (or possibly an overall limit of entries for everything). If I loaded too many they were still on the device, and could be seen when connected to a computer, but weren't listed if you tried to access them. If you deleted the other routes they would then show up. I have an edge 1000 now & haven't encountered this sort of problem - yet!

Thanks that looks a lot better than the manual.

Dunno about an Etrex, but with the other Garmin devices I've used, the SD cards need formatting.

Create the following directory on the microSD card: Garmin/GPX/My Tracks
Put your GPX tracks into the My Tracks folder. That's it.

Which etrex? On mine (quite old, venture cx, I think) you can put tracks on the sd card but it ignores them. You can only put useful tracks in via a USB wire from a PC or something else that will talk the garmin protocol. I think newer ones are different.

It's an Etrex 20x. I can now see the tracks via the Garmin that I've uploaded on the SD card through 'Track Manager' as per my post yesterday 4.44 pm.
