UHI Port - Switched Power from Centre Console
For those of you who have a UHI installed and a pre-facelift (2002-2004) W203 and access to a multimeter, I am wondering if you can do me a favour and see what the pin outs do. In particular, I am wondering about the following:
a) Is the power switched, or is it on 24/7?
b) what kind of voltages are available from the different pins?
The port is some funky proprietary 10-pin so you can't just stick in a standard RJ-45 (Ethernet) plug, it doesn't fit.
The easiest way to test would probably to stick in a UHI cable, disconnecting the UHI end, then testing the pins from there.
I am wondering if buying a cord then cutting the other end would be a real simple way to attach a non-MB phone charger inside the console.
Thanks!

Come on, can SOMEBODY please do this? 
Just read on CNN that they're now making Micro-USB the UNIVERSAL cell-phone plug starting in 2010, so I am SURE people out there will want to do this thing.

^ Oh wow, someone still reads my old threads. 
Yes it's possible. The pin outs are here. You'd just need to run some wires out from the connector to the stereo as needed. 5V USB plug
With that said, I preferred this method instead. Much cleaner, and I can switch songs very quickly. Aux in
Let us know what you decide.

Hey Yeah! your results came up in a search and important stuff just don't die!
The armrest method seems complicated as you said, although i had a run at the second method sometime last year, but my Torx screwdriver was short to reach all the screws, and i ended up ditching the whole idea.
Now that i am back at it, was considering my options!
I once read a post with pics on how to remove the dashboard, seems to have been taken down.. guess i'll just try to remember
