I noticed nobody has a good DIY guide or video on how to remove the two-piece center console wood trim found on pre-facelift cars. I have just wired in a W124 radio antenna switch so that I can keep the power antenna down while using my stereo on bluetooth (DIY guide for that pending), and during that job, I thought to make this guide to help save the wood on all the remaining cars out there.

This guide shows removal of the upper and lower center console wood trim pieces, as well as removal of the ash tray wood trim, radio, HVAC (ACC), switches, and gear shift knob with shaft. If you have never removed the center wood trim panels before, be prepared with JB-weld or some other epoxy to repair inevitable cracked plastic on the switch sockets. And of course be ready to wait 12-24hrs for that to cure. Or, several people including: restoredinusa.com: Mercedes Wood Trim Restoration – We service customers from all over the world. - Mercedes Auto Wood Trim Restoration for San Diego Los Angeles California Florida Nevada Arizona Texas Washington New York can restore damaged mercedes wood trim; I'm not a customer (yet), and that's not a paid endorsement, but his results look far better than some DIY jobs I have seen.

Tools needed:
  • Right angle screwdriver with PH2 phillips and T15 Torx bits. I use "NEIKO 03044A 1/4-Inch Drive Mini Ratchet Screwdriver Set"
  • Mercedes stereo removal tools, found on ebay, the ones that look like a knife blade on a ring. See pic 9 in this guide.
  • PH2 normal screwdriver on a typical 4 inch shaft.
  • Plastic trim removal wedges, straight, X2
  • About 1/4" flathead screwdriver on a typical 4 inch shaft.

I also would recommend a headlamp to see into the crevices, and plugging in the car into a battery charger if you're going to take a while; using the dome light could run down the battery if it takes longer than expected. Working from the passenger seat may be easier because you don't have a steering wheel in the way.

Best,
Luschka

PS- As you can see in images 1 and 5, the rear-most edge of the lower wood trim piece
behind the shifter is bending up. It's not the veneer peeling, the whole wood backing is not quite sized to fit down flush with the center console. On these early year cars, there is no retaining clip to hold that portion down. I am curious if anyone has tried to bend this wood back to sit flush, or has fabricated some sort of hook to secure this rear-most edge down to the center console. Let me know if you have a solution.

PPS- Hot glue is a suitable fix when you need to glue directly to the switch to keep it in place, e.g. when the plastic tabs on the trim piece are broken and missing entirely. It holds tbe switch and it can be atraumatically removed from the switch at a later date to allow for replacement, unlike epoxy which is more permanent.

Well Done! I am interested in your antenna switch project!
I was able to wire a W124 antenna switch (I wanted to keep the power antenna down when I'm using other functions on the stereo), however I guess the signal for the amplifier to turn on is also carried by the light blue power antenna wire. I don't have an amplifier wiring diagram to confirm this. So the switch works to control the antenna height, but when you lower the antenna, all sound thorugh the speakers shuts off (must be the amp shutting off). So there is some work to be done before the project is a success. Maybe I need to find a switched ACC 12v power line in the trunk, and just wire the amp to turn on whenever the key is on ACC or on. However, that could lead to faint static noise from the powered on amp whenever I drive with the stereo off, which wouldn't be ideal.

The wiring I have done:
Antenna wire from stereo TO switch: from stereo connector, pin 5 (light blue antenna wire): cut, and wire to pin 3 (blue/green wire) on w124 antenna switch socket.
Antenna wire FROM switch out to antenna: from pin 2 (blue wire x2) on w124 switch out to the chassis harness portion of the above cut wire (sends the antenna signal after the switch)
Constant positive 12V: tap in to pin 4 on stereo connector (red/yellow stripe) and wire to pin 4 on switch socket (socket pigtail has blue/yellow wire).
Ground: tap in to any local ground (there's a good one forward of the shifter) or pin 8 (brown wire, ground) on stereo connector, wire to pin 5 (brown) on W124 switch socket.
Lighting for the switch: Pin 6 on stereo connector (gray with blue stripe), wire to pin 1 on W124 switch socket (gray with blue stripe)
Just need to be careful because the stereo connector has two banks of pins both numbered 1-8; all above are from the same half of the connector. The other half of the connector is just the wires for each speaker.

I have seen, with my particular car, that the automatic antenna has it's own fuse in the front fuse panel, so i'm wondering if I can incorporate a switch to that circuit leaving all else unaffected.
