Exactly, just to reiterate what's already been said, it would be in the trunk. I have an '08 G35x with NAV and the sports package and the CD changer is in the trunk.

 

Well then mine must have been removed... I know I have all the premium and tech options.

 

I have an 08Xs with every option (prem, navi, sport and tech).

Here's a list of general things to look for for each package. There's more to each package but it's easy to spot these.

If you have premium you'll have a backup camera.

If you have navi you will have 6 buttons on both sides of the center **** below the screen (6 on each side instead of the 3 on each side(non-navi).

If you have sport, you'll have paddle shifters.

If you have tech, you'll have an extra button on your steering wheel (right hand side below the on and off for cruise control. It will have 3 horizonal lines that indicate the distance you want to keep between you and the car in front of you when you're on cruise control.

Hope that helps.

Also, I do have a CD changed in the trunk.

 

Yes, I have all of those except the sport. So it must have been removed

 

Not to nit pick, but you actually can have Premium without having the backup camera. You need to have BOTH Prem and NAV to get the camera.

 

I stand corrected.
