Micheal if you have downloaded the maps or maps from MDC Go to that folder and double click on it. That should bring up another window with lake coords list on left and saml map in the right. Look at the top of that screen in the tool bar for SEND / Recieve. Click on send then click on ADD DEVICE then select your device from they drop down menu. Then it will send to SD Card. I think?
I' ll keep my fingers crossed.
