Update '08 ES 350 Nav Map
 

Just purchased a 2008 Lexus ES350 and would like to update the North American DVD Navigation map. The one installed is from 2007, Part # 86271-53022. I've seen non-OEM offerings on ebay with 2 disks but that doesn't seem practical, since we travel from East region to West region on most of our trips. Thanks for all help.

FYI, you can operate on one DVD if you buy from Ebay to navigate through all US cities, the second DVD is only needed for POI. so I can have one DVD for the east and go all over the US with it, the only thing i cant see is the POI of the west.

I bought one that contains two dvds for 15$. I thought they are genuine/OEM, as per your post they are not.
