I just bought a copy of CNDV-70M off of Ebay. CNDV-60M came with my D2. What's the difference between 60 and 70? Seems like the maps are the same. For example, a couple roads that I know differ from the map in 60, are still not updated in 70. The Pioneer boot screen looks nicer, and is more up-to-date, but nothing else that I can see.
Thanks.
