I'm a NOOB with possibly the dumbest question ever but here goes anyway... I'm seriously considering buying a beautiful '04 GX470 but it is equipped with the Mark Levinson audio system. I've test driven the truck and LOVE IT but I'm concerned that the lack of modern features on the ML system is gonna drive me nuts. I've been poking around the forums and YouTube for a couple days now looking for solutions and an not very thrilled with the available options. Can anyone please tell me if the climate control unit from a non-navi GX could be installed allowing all the ML equipment to be pulled out for a clean install of an aftermarket system? Any help would be greatly appreciated. Thanks.
