Kenwood has a pretty sick deck out now, its a double DIN, so it would fit the whole radio opening, and the whole faceplate is a monitor. Its a touch screen, which works most of the controls, and the more common controls are on each side of the screen. It has a navi input for use with their navigation unit... for both units you'll be lookin almost $3000, but it is a very slick setup. Much better than a flip out monitor IMO. The navi unit gets mounted elsewere, like in the trunk, and there in an external antenna for the GPS. The deck is also a DVD player, so you can watch movies or hook up a PS2 or other game console. As far as I'm concerned, I think its the best way to go. Putting a TL dash in your car would be a ridiculous amount of money, and not worh it for just a navi system.
