Question About Garmin Nuvi 200w Product Registration?

I just got a Garmin Nuvi 200W for Christmas and I’m trying to register it through Garmin.com. It says I need to update the software, but when I try it keeps saying there isn’t enough space on the device–clear up some space to continue. How do I clear up space on a new device!?? (It was purchased through Best Buy so it is new)
Someone pleaseeee help! This is my first GPS device.
Thanks.
