if I load in the n3 discs cndv-60mp discs what should I expect to change? I know I will have to do the bypass on the board for the n2 and ground the parking brake. But anything else?

Aside from updated maps and I beleive some cosmetic differences in the looks of the on-screen buttons. Oh the final thing on some multilane roads the avic will show you which lane to be in. That's all I can remember at this point.

so....if i get the discs all i'm getting is the cosmetic upgrade, correct? Is there anyway to get the improved performance of the N3, or do i just need a new avic brain? I'm not worried so much about the cosmetic stuff as I am the iPod functionality. I heard it's much better and user friendly on the N3 than the N2. So where do i go from here?

N3 brain for upgraded ipod/xm interface.
