I believe the Avic Z2 has a 30gig hard drive that can store the Nav data full time...

the Avic D3 (what I have) only runs off of the DVD, but once a route is calculated and being actively used, you can remove the DVD and it runs of temporary memory. CDs are pointless with the seamless IPod controls however, and I am yet to watch a movie while actually driving, so...best value ever is Avic D3...
