			Hello,
I am using a couple of Mio Digiwalker C310XGPS units from around 2006.  I was using a TOPRAM SD 150X 4GB memory card which was recommended to me on a GPS forum.  Some of the cards are failing now.  Does anyone know where I can get more of these cards or something else that would work for me? 
I tried to format them and copy the files from a working card to another card.  It would not work in the GPS unit.  I hope that you can help me.
I am also looking for fairly current North America maps.
Thanks.
