You can just make the jump directly to the latest version, no need to get everything in between. Also, you nav generation never changes. If your nav is Gen6 (2010 4Runner), then you always stay with that generations update which in your case will always be released on disc. My chart simply details what Gen each model year nav system is.
Definitely not worth it to get the disc at the link you provided. There are great places to obtain much cheaper and more reliable too.
Awesome great info!
Where do you recommend one purchase the newest most up to date NAV disc?
