Help!! I recently installed a Kenwood DNX7100 in my 2000 E430. I was told by a couple of car stereo stores that I would be able to interface the factory steering wheel controls to the Kenwood unit very simply. That has turned out to be false. I'm hoping someone on this forum can direct me to someone or someplace that has the ability to do custom electronics and allow me to use my factory controls again. The Kenwood unit is a Stereo, Cd/DVD/GPS/XM/IPOD....unit and the GPS's superiority over the factory unit is why I installed it.
Any advice/help will be greatly appreciated! I'm guessing that I'm not the only E-Class owner who wants a better Nav unit and that maybe this has come up previously.
Call these guys at hifiaudio.com and purchase the SWC module that matches your vehicle (ask for Scroche brand). Once you purchase the SWC module, make sure you read the installation instructions two or three times before you install it. Once installed, these SWC units work great. I just completed the installation on my 2008 F150 with the Kenwood DNX-7100 and my steering wheel interface works perfectly.

If your headunit is in protect mode, the most likely cause would be the speaker wires are shorting somewhere. The most likely place would be the connections behind the stereo with an inferior installation. The next most likely place would be at the speaker connections, especially if the speakers were recently replaced.
sounds like the speaker is not grounded and to by pass the amp there are two way unhook the speaker wires to the amp and trace what color is what or just run a new speaker wire from stereo to speakers i hope this helps.
It sounds like there is a short somewhere in your wiring. If the problem got worse when you installed the aftermarket stereo then it may be on the factory side of the plug. You may try powering the stereo by some other means. For example, try a wire with an inline fuse directly from the fuse block to the power wire on the stereo. You can also tap into the ignition wire that way the only way it will get power is when the key is turned on. Don't forget the inline fuse if you try it that way. I had to do that with a stereo I once had.
the usb port it's a cable coming from the back of the unit and has to routed somewhere where you can get to it.
I know that if you install the bluetooth unit, you can connect another device to it because has a pass through connection.
if you have an earlier unit(serial#8020...) you will most likely have issues with the HD. doesn't hold the memory presets after shut down. Service dept. has to change an EROM inside the DDX.
sirius won't become xm pretty soon?
I own a DNX5120. I'm not an expert, just another owner. Our units have a new firmware 1.40, if you don't have it yet, download it from Kenwood. Bluetooth also has one.
