For some reason, the ETK for E30 does not have a section on a regular phone, although this option was available, and in several variants. Installation of the telephone in the E30 is described in the EBA factory instructions and shown in the company booklets. I already wrote about this in detail before, so I won't repeat myself. I installed the GSM phone kit taken off the E38, so the setup is not exactly factory, but not by much. Now I will write only about the installation of the wiring, and after the assembly of the cabin I will write about the installation of the phone itself and the speaker system (hands-free).
So, the set includes power wiring for the telephone unit, direct telephone wiring, speaker system wiring and an antenna cable.
The power wiring of the telephone unit looks like this:

1 - power connector. By default, the phone's power supply is connected to the C103 connector, but I thought it would be more convenient to duplicate it from the radio's power supply to a separate connector:
BATT+ constant power from the battery - C302 (V)
ACC+ power supply from ignition - C302 (X)
2 - speed signal connector for volume control (any of the three identical pins in the green connector on the instrument panel C6 (Tempo)
3 - the connector of the front left speaker for the speaker system (hands-free) - the second pair of contacts
4 - the connector of the front right speaker for the speaker system (hands-free) - the second pair of contacts
5 - connector for connecting the phone to the radio (TEL MUTE and I-BUS). Muting the sound of music during an incoming call TEL MUTE also works on most standard E30 radios, and in order to display the number of an incoming call on the radio screen, you probably need to install newer models of radios that support I-BUS.
6 - connector for backlighting the phone buttons. I connected it to the backlight of the rear ashtray, with a separate connector, together with the backlight of the buttons for heating the rear seats.
7 - "mass" terminal G300
8 - phone ECU power connector
9 - phone ECU connector for hands-free system
10 - speakerphone microphone connector (hands-free)
Telephone wiring:

1 - phone ECU connector
2 - connector of the telephone ECU for the speakerphone system (hands-free). Connects to connector 9 of the previous wiring.
3 - phone ECU power connector. Connects to connector 8 of the previous wiring.
4, 5 - base and handset connectors
In addition, an antenna cable is connected to the ECU. Without an antenna, the phone may fail.

The SIM card is inserted as a whole.

The ECU is normally installed on a special bracket on the rear left wing trim. But I installed it under the rear shelf because this ECU is much more compact than the older models. He became very good, as if he was there!


We connect the wiring and antenna cable.

By the way, about the antenna. A separate GSM antenna is used for the phone. But you can install an adapter to use one antenna for radio and phone. I don't know what it is called, but I found two such units and several telephone antennas. Even one more Soviet-made on a magnet! :)

There was also an idea to make a spaced antenna using the filaments of the rear window heating, as in the newer BMW models, but for this the heating would have to be physically separated into separate parts. Well, this idea was shelved, and the remote antenna block remained unused :)
But I did install the block for the radio antenna so as not to install a separate antenna for the phone. The VIMAR unit had a less attractive appearance, so I chose the KATHREIN unit, especially since the GSM antenna was also from this manufacturer.

Made a short antenna cable to it.


Installed and fixed together with the rear lamp control unit.

I connected the antenna cable of the phone and the radio. I will write about wiring the radio antenna separately.

In the cabin, I laid the power wiring along the left threshold and connected it to the separate connector from C302

I laid the telephone wiring under the back seat and through the checkpoint tunnel.

I fixed the wiring on the tunnel with tape. The connectors of the base and the tube were brought to the back of the console, and the microphone to the front. I will install them after assembling the interior.

Connectors of the speaker system (hands-free) are connected to the front speakers on the left and right. Speakers have two pairs of contacts - separately for music and phone. I will install them later as well.

For now, here's an old photo of my installed phone

But the video of his work
Next time I will write about the electric antenna.
