Boyd & Seldon - Thanks for the quick reply! I'm sorry that I forgot to say I'm using a Mac with Snow Leopard. I seem to understand how to do the changes I wish to make on my Oregon 450 but can't figure out how to delete the old maps from BaseCamp so I can replace them with updated versions. Thanks again.
How do I delete old rev maps from BaseCamp and from my Oregon 450 so that I can install newer versions. The maps in question were all downloaded from GPSFileDepot. I'm a newbie to GPS and not very computer savvy. Thanks for any potential help.
Hi - I'm totally new to GPS usage & at best a novice computer user. I have recently purchased a new "Oregon 450" and am trying to install some GPSFileDepot maps on a 4gb microcard installed in that unit. I am using a iMac computer & have downloaded "Basecamp"& "MapInstall" from thr Garmin site. I have successfully downloaded WA Topo & NW Trails to the GPSr internal drive and AZ Topo to the microcard. When trying to add SW Trails to this card via "MapInstall" I receive the following "Alert" message - "The mapset is approx. 0.4MB but only 3382.9MB ia available in the destination. Please select fewer maps and try again." This message makes no sense to me. Any help as to the sorce of my problem will be greatly appreciated!
