armani72, you started two separate threads asking the same question? Plus you posted in the wrong forum? The moderator is not going to be happy about this!!!
There is currently no map update DVD for the 2011 Honda Odyssey. Future updates should also be on DVD and loaded via the CD slot. The CD player is not just a music player but can read multiple disc formats including data discs and DVDs.
Merged threads and moved 'em. Please post in correct forums to prevent thread locks in the future and generally it is NOT a good idea to post the same question in new threads at any forum not just Odyclub.
