Has anyone replaced their old NAV CD with a new one? I have a NAV CD in 08 IS 350 and was looking for a NAV CD from 09 or 10. I don't want to pay the dealer full price for the new one, I would rather pay one of you for a newer one than mine.

 

sewell has the 8.1 in closeout right now...your probably running 7.1 if i were you id find a 10.1 one year up isnt worth it IMO

 

how much do these costs?

 

Thanks for the advice, I will start looking for a 10.1.

 

I've never bought a navigation CD before but in the future do they come with serial keys or anything? Are they one time use?

 

No they don't. Any one can be used. It's not a one time use because it'll need to be constantly used whenever you access your nav. You'll just need to make sure you get the correct DVD for your nav gen.
