Click HERE for all the info you will need to get registered and started with your Gypsy!
I just downloaded the Gypsy Sync software to my Mac. Then, I opened the Gypsy Sync software, which prompted me that I needed to register my Gypsy. It sent me over to the registration page, where it autofilled all my info, including my Gypsy serial number! It was so easy! After registering the Gypsy, I went back to the Gypsy Sync software and did "check for updates" and finished. There weren't any updates for it. It was ALL SO EASY!!
