This Old Guy way over his head..... trying to download to Oregon 450 highlighted Illinois area map portions to microdisc as per tutorial instructions using BaseCamp. Portions are recogized and sent. Even get the positive final message.
However no such files are found anywhere in the left hand margins folders. Help!! Really lost. Is there a do over 
Should I download map source? Is windows 7 the culprit &/or my ineptitude? Your tutorials have been by far the most informative, but I do not get exactly the same described screens (no written names Ill. topo, etc.). For the soon to be senile please keep it simple....... Much thanx in advance
