I am about a week into my 2009 (new for me) MDX. The map on the nav screen lacks many of the streets I travel in Omaha. How up to date are the upgrades?

Also, it seems the Wal Mart GPS in my last car had a lot more information than the high tech navigation software in my MDX. Many of the roads, even older ones, in Canada are also missing. My Wal Mart GPS had all of the ones I travelled several years ago. Not a huge deal, just something I noticed.

 

I believe alpine releases navi disc annually. If you search you can find coupon code for $99 disc.
