I've had my 2012 Tacoma Double Cab 4x4 for a couple of weeks now and have made some observations.
First the 12s have a new hood, fenders and grill so swapping my hood for a sport hood may have to wait awhile. The dealership wants $695 for a new hood plus paint.
I've noticed the navigation system is lacking a couple of things. First the vehicle information isn't available on this truck. Second the integrated back up camera doesn't display the lines as does the smaller ones in the rearview mirrors.
I've also noticed a wind noise that I haven't diagnosed quite yet. I've thought it was a rear door not shut tightly but that's not it.
The wait for a truck with the Nav was definitely worth it! The upgraded stereo including the sub is awesome. Im very happy with this truck and I haven't even had it off road yet. The above observations aren't really huge things but since its a new truck I thought I would share with anyone considering a new truck.
