After recently purchasing this 2005, I found that it still had the 2005 DVD in the NAV, I updated it with a 2009 version that I bought off Ebay, but it's still not "finding" addresses (homes) built in 2005-2006! All my local Lexus dealers (Central Cal.)say the 2010 NAV DVD's are on back order, has anybody been able to locate a 2010 version of the NAV DVD? My Garmin works better than this!

Combined.....as I drive on the highway to get to work (10 miles) then the rest is in town.

I' m getting about 13-14 MPG from my 2005 LX470, I realize these are not "hybrids", but I'm curious if there is anybody out there that might be getting better mileage than this? I'd be happy with 16-20......I'm talking in town and highway combined. Any aftermarket "device" that really works? Reasonable (money)modifications that can help? Thanks...............
