I asked this question over on the G37 forums so hopefully someone knows what I am talking about.

I owned a 2006 G35 which I bought used. Whenever I had the moonroof open and parked the car the moon roof would automatically close.

It didn't have an aftermarket alarm and I thought it was a built in feature to the car.

So of course I asked if the G37 had that feature and 2 people answered that it doesn't make sense to have that.

I guess to each his own but now I forget to close my sun roof when I get out the car. LOL

If there is some aftermarket doohickey anyone know what it is?

 

It could be similar to the window modules that are for aftermarket alarm systems that you connect from the shifter to the module to the auto close wire from the switch to relay it shouldnt be to hard for any alarm shop to do it.

 

KP technology sells a module kit for this feature you're looking for. They also have other ones as well.
