hey guys, bought my Z the other day and have quickly noticed the stock Bose stereo isn't great. Im looking at buying a new headunit with the touch screen display, like a kenwood or alpine. Probably the kenwood. Is there a adapter kit for the installation of the head unit, or does it fit in the stock brackets for the old bose unit? how did you guys that have done it do it? did you buy one of those kits for aftermarket stereos or modify the original equipment that the car came with? Cheers Ben
