Yust go to www.mapwel.biz/down.htm get software MapUpload and now you can upload any map to micro sd card without loosing your existing map.

Have you got GB Discoverer on the card? The map should appear on the Map Information list in the Setup > Map area. Double check the placement of the map card. Also, in case you have not found it yet, there's wealth of information on the Oregon Wiki here: garminoregon.wikispaces.com

I don't know for sure, but most likely the problem is that iTunes keeps songs in AAC format, and the Garmin wants them in MP3 format.

If that's the case, then what you need to do is this:

in iTunes, build a playlist of the songs you want to export.
Click on that playlist to show the list of songs
Click on the first song in the list, then hold SHIFT and click on the last song in the list so they're all highlighted.
Select the menu option "Make and MP3 copy". Apple keeps moving this option, so you may have to hunt for it, depending on the version of iTunes you have.

This should leave the nice-quality AAC versions alone, but also make MP3 copies of each song.
Copy the MP3 files to the SD card and try that in your Garmin.

Hello,

The voice files must reside within specific folders before the Garmin will recognise them.

Please call Garmin Support for assistance.
