I figured I've messed something up.  Can't figure out what I did though.  The file 162-6916-MWtopo_install is definately located on my GPS.  When I connect it to my computer it shows as my F drive, and that is where the file is located.  I have searched for it on my computer hard drive and it is not on there. 
When I did the download it seemed to go fine, and then as soon as it was finished downloading it switched over and started copying the file to the F drive (the GPS) 

I'd love to just delete the file and start over, but when I open the F drive and try to click on the file it locks up and I get the message that F is not responding.  So I can't even figure out how to delete the file and start over.

I have ordered a new memory card, and will have to start with that I guess.  The 1GB card that came with the unit is about filled up with the file I downloaded.

I just received a Garmin 60CSx unit and tried to download maps from Midwest Topo United States.  Eventually they seemed to download properly, and automatically copied over to the GPS unit.  But I can't seem to do anything from there.  I can see the file, but when I try to open it (162-6916-MWtopo_install)  it locks up my computer and I get the message that the program in not responding.  On the map setup page of the unit I don't see any maps listed.  I can't even figure out how to delete the file and start over. 
Thoroughly confused!!
