Pioneer has had touch-screen A/V receivers in the past, but they are now trying to make it more user-friendly for iPod users.  The new unit has an improved iPod interface and offers many other features.  See below for details:

Now Playing In A Dash Near You
This is what Drive-In Movies were supposed to be. Audio/Video players improve on CD Players by adding a nice large touch screen. With features like touch-slide control and improved iPod interface, taking your favorite movies, music, and other media on the road is better than ever.

		I Can See Clearly Now The 5.8 inch wide touchscreen on the AVH-P3100DVD allows you to enjoy all of your music and videos in style. Sick of having to search through your music song by song? Now you can scroll through your music at the touch of a finger.
		iPod Made Easy Simply plug your iPod directly into the unit using the CD-IU50V iPod cable, and you are ready to rock and roll. Touch slide scrolling, Alphabetical Hi-Speed Search, Album Art, and improved Link Search make it easy to find your music.
		Bring Your Music To Life Hear the detail, warmth, and clarity the way the artist intended it, from all of your highly compressed MP3, WMA and AAC files. By restoring data that tends to get lost in the digital compression process, we can make your music sound close to CD quality.
		Smooth Operator. Controlling your movies and music has never been easier. With a smooth swipe of your finger on the touch panel display, you can fastforward and rewind Audio/Video* content. *Touchslide Fastforward/Rewind function not available on iPod
		Now It’s Personal Select among five display colors and 112 key panel illumination to match car interior lighting, color, and design. You can even set your favorite JPEG file as a wallpaper. Parked with no place to go? Now you can enjoy a slideshow of your photos on a CD or USB Device .
		Fed up with your Bluetooth headset? Here’s a better hands-free solution. Use the available CD-BTB200 Bluetooth Adapter and Bluetooth-enabled cellular phones for easy, safe, and hands-free operation. The unit acts like a speakerphone, channeling the sound through your car speakers which makes the call sound better. It also automatically mutes your music so that you’ll never miss a call. *Optional CD-BTB200 adapter required

  The Fusion CA-IP1500 is the first (that we know of) car stereo to have its own ipod dock built right into the unit itself.  The faceplate on the Fusion folds down to reveal a slot where the iPod slides in.  The stereo then controls the iPod with scrolling menus like you would expect.

The unit works with just about every iPod, but no word of iPhone.  We would assume the iPhone is included as the iPod touch is in the list.  The question then remains if there is a bluetooth option for phone calls

The Fusion CA-IP1500 is around $300 and will need to be shipped from overseas.  Hopefully Alpine, Pioneer or one of the other domestically sold car stereo manufacturers would use this idea in their next revision of products.
