Are there any newer Nav discs out there for the D1? i'm new to the site and a new owner of a pioneer Avic D1. I'm not sure if my discs are up to date or not.

Thanks

The D2 disks are newer. The D3 disks should also be out in a couple months. They will both work on your D1

you can look at the disk your using to see what you have. If its an original then itll say for sure what it is. If its a copy, then likely it is something upgraded, but not definite
