Got the 478C. Looking to install topo maps - need to purchase disc and card to load them on to?? - What card standard does this use? SD card? Garmin site doesn't say. The BluCharts seem adequate just driving around in Cordova, except highway 10 ends in our garage. I'm not so sure that this is what I want to end up with, so it's lucky that I spent $25 for a 90 day return policy. More testing to follow. Does garmin's mac software obviate the need for the usb/serial cable and Keyspan adaptor? Bert
