Waypoints on my nuvi 50 appear to be "read-only" - how do I delete them?

I have just downloaded BaseCamp - great looking application, I can do everything I would expect to be able to except change or delete waypoints already on the device. I can copy them off the device, change them, then copy them back, but then I have both the new and old versions on the device... How do I stop the information on the device being "read-only"?
