For "usr" files any SD reader will work( or the XOG itself) , but for Mapcreate Topo maps you need their reader/writer., But any maps you have already put on an SD card for your ExpedtionC will work in the XOG,
Remember if you put "usr" files on the SD card using the XOG as the SD reader, you must power it down and back up before the XOG will see the files that you transfered, or eject the card and back in.
