in need of some friendly help..

g35300mm

Well,

The time has finally come to give backy my G35 and get into the Z ive been waiting for. I cant seem to find many dealers that have these things in stock so decideding on what to do has become a little bit of a pain.

My question is over here in canada the option for sport pkg is $4000 and the option for nav is $2000. I wont be able to afford to have both so i must decide between the two. I really dont mind the Touring pkg and what it comes with(being our base model in CAnada)), but of course the sport give you much more. And as for the nav.. a couple friends of mine have nav in their car and say they either never use it or that its ****. Does anyone have any video's or picture they can post up on the Nav unit for the Z and how it operates. Also i think i already have my answer but just incase... is it DVD based?

Thanks a bunch!
