You want it all, right here, right now, in your car? You got it. Pioneer's AVIC-D3 is the at-your-fingertips apotheosis of no fewer than ten systems: AM/FM, CD, DVD, satellite radio, GPS navigation with optional real-time traffic info, multiformat digital audio and video, Bluetooth cellular and audio, and iPod interface. Go Rachmaninoff on the 6.1-inch touchscreen to switch easily from one app to another, play movies for whoever's riding shotgun, and, if you're going for a really, really long haul, shuffle those 2,000 tracks on your Nano. $1,000;
