Top 10 Touch-Screen Devices

Pioneer Avic-Z110BT, $1,799

When you cram this many features into a car receiver, it had better have either mouse and keyboard, or a touch screen. Pioneer wisely chose the latter for its flagship receiver, which will play DVDs and MP3s from CDs, DVDS or SD cards, route calls from your phone to the car speakers via Bluetooth, control your iPod, and of course, get you around town, all using a gorgeous 7-inch touch screen.
