I own a 147 in Australia and have a Nokia 6310 car kit. When I installed it there are inputs labelled TEL AF+ and TEL AF-. Does anyone know if it is possible to wire the Nokia car kit so that it displays on the dash, or that it sounds through the stereo speakers.
You must connect the speaker wire of your Nokia CARK-91 (the mini jack with the speaker attached to it) to the AF inputs.
This means you have to cut off the speaker and connect the red wire inside the black spekaer cable to the AF+ and the black wire to the AF- input of your radio.
In this way, the sound of you carkit will be heard over your radio. For this, you indeed need to have the mute wire installed, the radio will the show "PHONE" when the telephone is activated.
In the MENU of the radio you can adjust the pre-set volume of the sound of your carkit on the radio (only when the telephone is activated though). But during a conversation you can also always increase or decraese the volume with the normal volume buttons (even on the steering wheel)
