Hi - I have two N1's. One installed for a couple years and one coming from an eBay purchase.

My question is that I have always stayed with my original disc set (V 1.1 series 40?) because I heard that installing any newer discs (I have a 50 set) would permanently disable my ability to watch DVDs while driving.

Can anyone explain the issues of upgrading? I am not sure what version my new (to me) N1 will have.

Thanks!

GW
