Where do you go to update the Honda Navigational System for a Odyssey?

Answer 1

Actually, you cannot order the update DVD from a Honda dealer nor can a Honda dealer order one for you. Honda thinks for some reason that dealers will go crazy and horde the supply of discs in inventory so they won't allow the dealers to order any. You have to order the disc yourself. Here's how to do that per Honda

ORDERING A DVD
You can simply call the number below and order one over the phone. There are several versions of the DVD available depending on the year and model (different colors for different years and models) but Honda says the phone center can figure that out--Here's who you call:
The Honda Navigation Disc Fulfillment Center
(888-291-4675) will know the correct color DVD
application for each vehicle, and can provide the latest
version.

You can also order online:
When ordering online, go to www.Honda.com,
then select Honda automobiles. Enter Navi in the
Ask a Question box, then click on Order update DVD.
You will then be prompted to enter the year and model.
The site automatically references a current DVD
application chart, and selects the correct color and
version DVD for you. You are then given the choice of
a Coverage, FAQs, or Order link.

Your navigation system manual that came with the car provides additional ordering
and installation information. This information is located
in the Customer Assistance section of the owner's manual.

Hope that answers your question

Answer 2

The Navigation System is a CD/ROM based unit that should be upgraded every tow or three years to account for new streets, businesses, etc.

The New Update is available from your Honda Dealer as a cost of around $150. (which explains why two to three years is often enough)

You can either reload the CD yourself or ask them to show you how. It will only take a minute. The unit is located under the front passenger seat

Hope this helps

Answer 3

You can order it online at most dealer websites and have it shipped to your house if you like. It is a DVD disc based unit. CDs were for the first generation.

Look for a link on the dealer's website called Honda's e-Store

As far as actual location of the drive, it is under the passenger side front seat

Answer 4

Your Honda dealer's parts department.
