aj-On the ES it isn't that much($)but on the LS/LX/SC/GS it is big money, or at least it used to be! I too was impressed with the system on my 99 cadilliac catera it was bose and very good(it even played upside down while the car was on fire!) But now the monsoon nonsense in my GTi is JUNK! but it was only $300. After spending 30k on a car system and still not being happy with it I gave up, a loosing battle, the 12 volts D/C is a great idea but that's where it ends, IMO.
