Hey I have read a lot of posts on here and I haven't seen many topics like this and none as specific as I would like. The one and only question I have is on the Pioneer AVIC-N1 unit, will the unit be locked out from playing DVDs and Nav while driving if I update to the Green version 1.2 disc? Because I have recently done that but my unit is curently being repaired for none of the buttons working, the screen not displaying and no longer coming out. Thanks for the info and help everyone!
