How come on the GT3 if you don't get nav the look of the dash is different (no screen), yet on the other carrera models, you get the screen regardless if you order NAV or not.

Thanks,

 

Weight savings I suppose... The figure is somewhere, but w/o the full Navi system, you save "x" number of pounds. The GT3 is supposed to be the hardcore model.

 

You do get some nice features with the NAV - i.e. ability to adjust certain light settings. My 07 3 has it but I didn't require it

 

PCM is a an option in the 7gt3. but you cant get it with BOSE only extended sound package (ASK which is analog).

 

Weight is a funny thing ... once you start checking whether it's real.
When you put a claimed "light" car on corner scales in front of the owner, you often get priceless faces.
Like when we measured the 430 Scud barely 50kg below two other 430s.
Or when a GT3 RS came in only 12kg below a stock GT3, both with steel brakes and full tanks of gas.

So I am not sure how many pounds are saved without PCM, but I am quite confident that it's negligible compared to the "optimism" of manufacturer claims.

 

Does anyone know of a navigation unit that can be installed in dash on an '04 GT3?
