Are we etitled to one free map update on our Garmin Nuvi 200 that we purchased in 2007?

We bought at Garmin Nuvi 200 in 2007 and have never updated any maps. Occasionally now, we get a message abouyt updates when we first plug the Garmin in. Are we entitled to any free update on this 4 year old product??

Garmin Updates, some free, some not so free. :-)
