DVD Nav upgrade
 

What is the difference between getting the DVD Nav upgrade from Mazda on cd (FREE) vs getting the upgrade done by Mazdaparts.com for $95... Has anyone paid to get there Nav updated from mazdaparts. What is the difference between the 2 options we have for upgrading the navigation

Thanks

Read this thread.

Basically if you take the thew path you get a newer version of the firmware than what the free CD gives you, and they replace a chip that makes the nav system's performance a lot faster.

I would have done thew's upgrade if only it didn't mean I'd have to drive around without AC for several days.
