What's wrong with aftermarket, less the integration? I also did an aftermarket Nav install in my G35 and it was much better than the Nav, had DVD ability, Play Station, Carputer, for less than $2000!

i dont think you will be able to have the stock nav installed, they couldnt on every car ive ever heard of having this problem. they couldnt on my friends 350z because cars with and without nav are wired completely different. the nav isnt just a nav system it also controls a thousand different aspects of the car...however the G does come with the screen and such and i had a 2007 g35 sedan wit nav and now have the g37 without nav and there is very little difference.

It's not that it CAN'T be done.....it's that it's no longer a $2000 option at that point. And to be honest, if I didn't have Nav I wouldn't even consider spending that kind of money to add it after the fact. Just spend $200-$300 and get a Garmin. It's a fraction of the cost, and for purely navigating, will work better.

i cannot see any aftermarket unit coming out any time soon for the reasons callaway gave. unless aftermarket nav makers can come up with a plug and play unit that can interface climate control and radio, trip computer etc., it is not a viable option.

also, i can almost guarantee that a dealership would not touch a factory nav swap with a ten foot pole.

The screen has to be changed too, non-Nav vehicles do not have a 'touch' screen.

For $100/hour they'll touch it all night long!

I talked to a customer at the dealership who wanted to do the same thing and he said they told him around $6K to do it. They told him the harness in the back is different between the navi and non-navi units (i thought it would be the same). Plus you'd have to get work done on your steering wheel to accomodate the bluetooth and voice buttons. Plus it'd be a ****load of labor costs. It's just too much work for something that should've just been purchased in the first place. You're much better off going aftermarket at this point.

Not to mention all the buttons and the area underneath the screen, that would have to be all redone as its diff. between nav and non-nav cars. At this point, if you just need a navigation for navigating, get a portable one. Cheapest and easiest solution out there. That or just taking a hit on your car's value and buying/lease another G with nav

Yea i think if your gonna add... do the OEM nav..

the only reason i didnt get nav is because i want a 6 disc changer and a dvd/ tv tuner based system.... id rather have that than climate control buttons, to each his own though.

Umm, regardless of whether you get nav or not, the temp control buttons are the same. The temp info and status is still displayed in the main screen. So regardless of whether you have factory nav or not, my question still stands. How do you integrate an aftermarket screen to show the temp displays?
