MAPS DVD for 2008 CRV

Yep, unfortunately it will cost you $149 + tax and shipping. See https://hondanavi.navigation.com/product-list/Catalog/Catalo.... Check your dealer as well for any current discounts on parts that might apply. The current revisions came out in January 2020 and should clearly state that in the offering.

You might be able to find some "used" disks on eBay but buyer beware. I'm told (I've updated a 2013 Accord) that many are copies, old versions, etc. Note that almost all sellers say "no returns" so you are stuck.

I have a built in Nav in my car, but as far as I'm concerned it sucks! Difficult to do anything with it.
I prefer to use my stand alone Garmin DriveSmart 50 LMT-HD!
Cost me about the same as your DVD would cost and the Garmin has Lifetime map updates!!!

BTW: On eBay you'll pay about $ 150.00 for a DVD. Checked Kijiji for the GTA and there is nothing to be found there.

I highly support the use of a portable GPS as opposed to the Honda navigation system (which I have in a 2013 Accord). But the last thing the OP should do is spend $150 for an eBay supplied DVD ("On eBay you'll pay about $ 150.00 for a DVD"). The 2nd to the last thing the OP should do is buy from eBay. It is very difficult to determine what version you may be getting and even if it will install (many are copies). Use the link I originally provided (https://hondanavi.navigation.com/product-list/Catalog/Catalo...) if an upgrade is desired.
