Where would be the cheapest place or vendor to purchase an updated Nav DVD for a 2006 coupe? Do vendors sell them or does it have to be purchased through Infiniti?

I just purchased a 2006 Lakeshore Slate Metallic and it has no Nav DVD. Pictures will be posted later today.

Thanks

 

Vstypical used to sell the updated 2006 DVD map for a small fee.

You can get it for free if you can find someone who already had it.
Last option is either eBay ($?), Zenrin ($190) or your dealer ($190)
