W202 Aerial Fitment

I am trying to fit a new w202 aerial (the whole kit). I bought from GSF a new Hirschmann fitment it said on the website but it was a Beru kit. No problem I thought as it looks the same and I would just change the motor and leave the wiring. The damn thing though is different and the schematics is not very useful. The instructions are translated word from word from German which make no sense.

Two questions,

1. Looking at the pictures
I have connected one of the cables to the chassis (same as the old one) but the second (which in the old one went on the chassis as well suggests connecting to the stereo. What should I do?

2 Where is the power that should I connect it to? I have tried following the old wiring but it involves stripping the dash to bits. Any body knows where?

and 3rd as the bonus:

What the hell is this multi pin connector? I have followed from the back of the car and ends where the stereo is.

Looking at the diagram which is not very clear as you said
First there is the coaxial lead from the aerial which has to go to your radio -thats the thick one that exits from the aerial base with the phono type plug on the end of it. Then there is a connector from the motor which has 3 wires coming from it. first the power supply for the aerial.
one wire has to go to earth
one wire has to have 12v power- the diagram suggests tying into the permanent fused live feed for the radio before the dedicated inline radio fuse.
the other wire has to go to the "aerial up" signal from the radio which tells the automatic aerial to extend or retract.

I think the multipin connector is for a cd changer in the boot which you haven't got??

for the old aerial you should have a co-axial lead and 3 wires one to earth one to a 12v supply and one signal wire.

I have tried connecting the earth (brown short) to the earth in the boot and that was fine. The other two that ended up at the stereo i connected the red to my stereo "anntena power" and the black one to "antenna control" on my stereo (Kenwood). When I turn the ignition on the mast went up but the rotor kept going. Swiched the radio off, no change! Switched the ignition off and still no change, well apart from the rotor stopping. D/C the black cable with the engine on and mast went down but is temperemental.

Any ideas?

Now it got even more complicated. The rotor was making a whinning noise and only when I "helped" the mast manually it would raise or retract. I did remove the mast to see if it was a problem with the teeth but now it wont retract. I am getting so fed up with this as have spent all morning and afternoon with this stupid thing

I did the same job as you are now doing, but I didn’t interfere with the radio area of the car at all, every thing was done in the boot

In the boot you should have the existing coaxial lead, which I see is already connected and one red and one white, (or maybe one red and one brown) these leads all go back to the radio, as seen in third picture on the floor of the boot.

All you have to figure out now is which connects to which on the remaining wires, black is usually earth.

I got it connected and working sort of OK now. What I need to do is to figure out where the black one connects. Coax is working fine and the red one is power which connects fine and works (if d/c nothing works).

I have figured out that if I connect the black cable to the ant control/power control wire at the back of the stereo the mast goes up. When I disconnect it, the aerial goes down. I just need to figure it where to connect the black so it will retract the mast when the radio is OFF and raise when the radio is ON. Maybe the ignition but that will mean that the mast will come up when the ignition is ON but my Hirschmann did raise only when the radio was on.

Could you put up a picture of the wires coming out of the aerial, there should be 3.
You should be able to use the original and existing wires without bringing a new wire from the boot to the radio.

There were a different fitment. The original Hirschmann had a different plastic connector so I couldnt use that. This one is a Beru which has three wires as well but different connector. I used the original aerial coax but I had to lay the cables to the front. I will take a pic of the different connectors and fitments and post

I think the cable you laid to the front is the problem, if you could put the wiring back the way it was before you started and try again.

Below is how I think it works, when you turn OFF the radio, power goes to the white/brown wire, bringing down the mast, the motor stops, either when it feels resistance, or it cuts out automatically after 6 or 7 seconds.

When you turn ON the radio, power goes to the red wire, bringing the mast up, the motor stops, either when it feels resistance, or it cuts out automatically after 6 or 7 seconds.

The only problem is which wires connect to the two spare aerial wires? There should be a fuse in the back of the radio as well as a fuse under the bonnet.

You will have to chop off the original Hirschmann connector and connect wire to wire by twisting together and taping, this is more reliable than using connectors.
