Clarion has a new line of products coined "Car Multimedia" and well I think they are the state of the art currently available in the United States. I have the following Clarion products installed in my vehicle:
MAX2256 - AM/FM CD and Cassette Player with LCD Display, 2 DIN Size
5" active matrix Color LCD Monitor for
Radio Functions Display, Rear View CCD Camera, Spectrum Display,
7 Band EQ Display, TV Tuner and Video In Output Display1.
Motorized Fold Down Face. Remote Control. 
California Vehicle code section 27602. No person shall drive a motor vehicle which is equipped with a television receiver, screen, or other means of visually receiving a television broadcast which is located in the motor vehicle at any point forward of the back of the driver's seat, or which is visible to the driver while operating the motor vehicle. This section shall not apply to a mobile digital terminal installed in a law enforcement vehicle.
Meaning you can install a TV but make sure the driver has no way of seeing it.
This is some e-mail conversations I have had with people concerning the MAX2256:
On Cables and hooking up the system:
> Supposedly, this adapter enables the MAX2256 to hook up to the TTX7170 tuner module
Not directly to it, it is a cord that hooks to the back of the MAX2256 (in the CCD rear vision camera slot) and gives you 3 RCA plugs; 2 audio and one video. Then you could hook a VCR to these and display the vcr's video on the MAX2256 or if you wanted to do the TV tuner you have to get another kit that is the remote eye for the control of the tuner and the outputs for the audio, the video comes straight out of the tuner from a female rca jack labeled "video"
> which then allows the audio visual sources mentioned above to be shown on the head unit's display and heard through the system's speakers.
Yes but it is not necessary to buy the ttx7101 to display a VCR or any single source. The advantage that the tuner gives you, besides tv, is two other video inputs that you can choose between so you could really have a tv tuner, vcr, and nintendo and switch between them with no problem using the remote for the tv tuner.
The cords you need are as follows:
Connection Cable - CCA 389-700 The full number on the label is CCA-389-700-290-6642-10 This is the cable that plugs into the rear vision camera port and gives you the three RCA plugs off of the MAX2256 that will become the inputs for the audio and video The length of this cable is 2.5m Price around $100.00 U.S.
Remote Control Kit for TTX7101 - CAA-357-100 The Full number on the label is CAA-357-100-290-6642-00 You only need this kit if you buy the tuner. if you just want to hook up one video source you can just use the cord mentioned above CCA-389-700 This kit consists of: 1. A remote control for the tuner 2. an infrared sensor with a 9 foot cord that goes into the plug on the tuner labeled 'Monitor Input" 3. A 13 pin DIN plug that plugs into the C-bus DIN plug input on the tuner labeled "source unit" this plug has the 2 audio outputs on it as well as a battery and accessory wire for powering the tuner. Price around $160.00 U.S.
Antenna for TTX7101 I got the inside the window mount antenna ZC303 there is plugs for 2 antennas but one has been good for me so far Price $70.00 U.S.
Note these same pieces can also be used on the VRX8271 to display a video and audio signal.

Some Installation Discussion:
> HI- I am going to attempt to put the Clarion Max2256 into my Ford Econoline van. I was just wondering if I could get a height/width dimension from you if you have it.
I wish I had done exact measurements before I installed it but needless to say it is a true double DIN unit. The main unit is exactly 4 inches high with the screen unit being a little smaller, like 6 7/8". It is the standard DIN width, whatever that is, with the screen once again being a little smaller. Depth wise, 7 inches comes to mind but I was told to plan for a depth of 8 inches by many installers I talked to. This 8 inches starts where you want the face of the unit to be, I wanted the face to be flush with my dash trim, but if you do not mind it sticking out a little there is a rim for a dash trim piece about an inch and one forth back from the face. This would reduce the depth you needed to about 7 inches then and that would be enough to accomidate all of the wires and plugs on the back.
> Did you have to do anything real fancy to get it to fit?
Boy Howdy did I!!!! I think I mentioned on my WEB page that Clarion only says that this unit will fit into a Nissan or a Toyota with a double din opening. Well since they do not think anyone will try to install one into any other car they provide no brackets, instructions, trim pieces, or anything that would remotely help you in installing it into any other car. So you are on your own!!.
I first cut my plastic dash innards (the entire dash was removed from the car) to accomidate the general depth requirements. My dash is plastic to it wasn't that much of a problem. Then I had to fabricate a mounting system consisting of two rails (aluminum angle iron) that go along the side of the unit that attach the the dash at each end of the rails. The rails then had holes drilled in them where they intersected 1/8 inch thick aluminum plates that where attached to the unit via the holes pre threaded from that factory (to fit toyotas and nissans). I had to fabricate these side plates and transfer the layout of the holes from the unit to the plates. I also had to countersink the screw heads to that with the plate attached the entire unit would fit inside the two rails mounted in the dash. Then I had to position the unit where I wanted it so I could determine where to drill and tap the threads in the side plates for mounting. This was very hard as I had to guess where the final trim piece would end up (I had not made it yet). I got pretty close and now with my plexiglass trim piece on there it looks pretty good. So at this point I had it mounted and I was happy. I started to reassemble my dash with some of the pieces that I had taken off to aid in cutting. When reinstalling my A/C duct I found that it was hitting the back of the MAX2256 and was not allowing it room to install. I figured this might happen in my preliminary planning stages but my measurements showed that I would just have enough clearance, well I didn't. So I had to notch out a section of my duct (about the size of the back of the MAX2256) and built a template out of cardboard of how I wanted the cut out duct piece to look, and took it to a fiberglass shop where they molded a piece that would fit in there that I could silicone in place and seal up my A/C duct. Now the airflow to one of my ducts is a little less that the others due the the fact that I probably screwed up the aerodynamics of the ducts in delivering equal pressure to every outlet, oh well.
Once I had everything installed in the dash I put the dash in and then I had to make a trim piece out of plexiglass to replace the factory one from GM. I used the old one as a template to cut around the speedometer and warning lights, but around the MAX2256 I just had to do measurements and constant checking and fitting until I got it the way I liked it. Now the opening in my trim piece is flush with the screen of the MAX2256 when the screen is in it's full retractable position. The opening on the bottom is larger that the opening on the top to compensate for the protruding alfa touch control knob when the unit is folded down for cassette ejection/insertion.

The
ProSeries 6.43 System combines our 6.4LF 6-inch woofer, 4.4LF
4-inch midrange, and Neo 4t 1-inch tweeter into a unified
speaker system with the new 6.43X, system-specific, three-way
crossover. The 6.43 System employs our highly acclaimed
ProSeries drivers in a three-way configuration so
installers can group the 4-inch midrange and the tweeter
in kick panels or dashboards - locations which are
favorite for spectacular imaging. The woofer- which is
less finicky about placement - can be mounted low in the
front door. This allows for point source imaging through
the critical midrange and high frequencies, while the
bass frequencies are faithfully reproduced by the 6-inch
woofer.
The new 6.43X crossover offers three
tweeter level settings - 0dB, -3dB, and -6dB - allowing
the system to be fine-tuned depending on where the
tweeters are installed. Dual inputs and internal jumpers
allow the low-pass section to be separated from the
midrange and tweeter sections for bi-amped installations,
or combined for a typical full-range installation. A
clear acrylic cover highlights the crossover's audiophile
grade components. Gold-plated screw terminals at one end
ensure positive connections and neat wiring.
The combination of our award winning ProSeries drivers with the new 6.43X crossover makes the ProSeries 6.43 System the ultimate component package with unparalleled sonic performance and installation flexibility.
Needless to say, I like them very much and the crossover looks very cool, if you are into that sort of thing, I am ;-)
