W220 Widescreen Radio upgrade
http://www.oemcargps.com/mercedes-be...em-p-1171.html
i came across this product, it says:
Configuration parameter:
1, CPU: RAM 11-600MHZ.
2, WinCE.net 6.0 CORE.
what does it mean?
The description includes computer or PC type specifications because the unit does have a microprocessor to perform most of the advertised functions.
WinCE is an operating system, like Windows, Android or Mac OS. Core usually means the WinCE runs off of firmware and is burned into the unit itself (no disk to boot).
None of which are directly related to interfacing this unit to your w220.
Although not a MBZ unit, all of these head units are very similar in operation. I had a generic head unit like this a few years ago and tried it out in my minivan. I liked the functionality, but the operating system and firmware look and feel was still pretty primitive and I did not keep the unit. I could use it, but the it was not intuitive enough for my wife and kids.
Looks like things have gotten a lot better, I especially like the look of the W220 unit's buttons. But again, the base unit operation is still important to me.
Please let us all know what you think when you get your unit.

I'm sorry, but I think it is biased

Overview:
UVO -powered by Microsoft
* Bluetooth phone
* BT audio music
* Ipod connectivity and control
* Zune connectivity - full file readability
* USB drive connectivity
* Built in Jukebox - only 700mb
* HD Radio
* Sirius
* CD (wish that the CD could be deleted)
* FM RDS station information display
* Voice commands to place calls and control audio sources
* Back up camera with guidelines (tested to work)
Found brand new unit on eBay - dealer cost for this headunit is $1400. Ebay find for $299
Not plug and play, everything was broken down to the printed circuit board. Could not find all Kia mating connectors so all connectors were unsolder or cutoff and everything was hard wired. The head unit faceplate was separated and mounted in a used MBZ bezel.
Found a early "3 hole" bezel for $22 on Ebay:

Center splines were cut out to make one big hole in the bezel. Kia UVO chassis is double-din sized, but the faceplate is much larger and was designed to fit behind the Kia dash.
On the top of the unit, it shows 4 channels at 4 ohms, but no analog amplifier circuitry exists on the PC board. There is place for a common 4 channel audio amplifier integrated circuit, but none of the surrounding components exist. Many blank locations for these components.
Digital connectivity is Kia's version of SP-DIF. Head unit must be used with a Kia or Hyundai amplifier using SP-DIF. Alpine, Pioneer, or other aftermarket headunits with SP-DIF probably will not work. 7 audio channels are multiplexed in the SP-DIF signal. The amplifier has to de-mux these channels into 7 analog audio channels - LF, RF, LR, RR, sub, etc...
Had to find a Kia amp. Once found, had to ensure that the amp had a SP-DIF input. Even so, I guessed that Kia and Hyundai amps would use the same de-mux for the audio. They do

This is a full piggy back install. I did not remove any of the MBZ components. I tapped into speaker connections from the MBZ amplifier and disconnected the main connector. I can put the Comand back at anytime.
Now. You will need to change a couple pins out on the C2 connector. That's it. You need to change the D2B bus wakeup wire, and the two canbus wires. Basically you get the pin out list which I can help you with when the time comes and change them around it's super easy. For the speed signal converter. It has 6 wires on it. Power, ground, canbus hi/lo in and canbus hi/lo out. You will cut the two canbus hi/lo wires after you have changed the pins and solder the converter into it. Then you need two add a taps and connect the ground and power to the ground and constant power of the Comand. The speed signal converter does not hook up to switched power, but constant. I can give you the color codes on the wires for that too. The entire swap is alot easier than it sounds. The hardest part, and it's not even hard is taking the dremel to the dash and grinding off the four tabs. They have to be grinded off completely, and level with the dash as this unit is squared and the old one has a few units bolted to a bracket.
If you decide to do it I recomend you get a 3.5mm patch cable from an electronics store. You will cut the male end off and splice the three wires into the C2 connector if you want AUX, which incidently sounds absolutely crystal clear. That is only three extra wires (ground, left, right) and quite worth it in my opinion.
I buy the converter speed signal but I would like to know how to connect the wire because there are 6 wire 1 red (12v) 1 black (Masse) 2 blue can Lo (Blue, blue black) 2 yellow can hi (yellow ,yellow black)
in it pin should they be connected?
pin 8 (can-b lo) and 9 (can-b hi) are only 1 wire
can I have a schematic connection
thanks

I have ordered a similar one and I am upgrading from audio 30. The audio 30 unit is connected to the bezel and there is no where I can mount the unit (please see the attached photo). What should I do now? is there any mount kit or I have to change the whole dash unit?

The problem i had was: I broke off one of the pins trying to pull it out of the socket. and soldering wasn't too bad. I do not have much experience in soldering. Message me if you have any questions about this process and I will do my best to walk you through it. I would post pics on here if i could. i also have a full wiring diagram showing the pin swaps and how the speed signal get wired correctly.

If you could send me the diagram and pics it was very cool

Thanks
1. If the unit being sold does not have the cables with it (just the unit alone), can I use the fiber optic cables that exists in my 2002 S430? If not where can I get the cables I would need?
2. Does one need the code for the replacement '03 NAv to get it to work? (I know on my system if you where to pull it out you need it - it's a theft protection feature)
3. Are there any after market electronic link devices to expand features like: Bluetooth to link my iPhone, , live traffic feedback, and a backup camera to the screen when in reverse?
4. Are there any MB updates for the United States Map on DVD (newer streets added, 3D better graphics)?
Any and all thoughts are welcome, thank you!
