I got my brother interested in GeoCaching during the Thanksgiving Holiday. He went out and purchased a Whistler GPS reciever from Wal-Mart. I use a Magellan Meridan Gold. I download the *.loc files and use EasyGPS for transferring to my reciever. He downloaded EasyGPS and it seems it does not recognize his reciever. What software should he use for his unit? Should he take it back to Wal-Mart and get a different unit?
