Amazining isn't it? When I bought my 2002 Maxima the dealer forced me to get the Bose system so I could get the other options I wanted with the car. He didn't understand why I didn't want the Bose system and all I could think of was the Sting song that says "it takes a man to suffer ignorance and smile".
Well I am done with Nissans b/c of poor reliability and paint chipping on 2 Maximas I've owned and I've moved on to Acura where I enjoy DVD-A on a pretty darn good Panasonic/ELS system.

Oh and most importantly, I have 25k miles on my TL and have had no service issues at all and no paint chipping and no Bose!
BTW on the 2000-2002 Maximas the stock system is a Clarion (head unit and speakers). The Bose system upgrade is $1100 and all it does is give you the identical system with a 6 changer and a Bose powered sub and a Bose nameplate on the Clarion head unit. Isn't that nice?
