Early Audio 30 with phone wiring diagram needed

[PeterE320Cdi]

I have a year 2000 W210 E Class with Audio 30 and the original phone installed. The Nokia 3110 like this.

The radio broke so I decided to replace with a new radio which has bluetooth built in.

Only problem is that I can not find the live ignition wire. All the wiring diagrams I can find online are for the later models which have 5 wires in the A block pins 4, 5, 6, 7, 8. Mine has only 4 wires in Block A in pins 2, 4, 5 & 8

I have found the permanent live feed and the earth but the other 2 wires show no voltage with the ignition on. To get the radio working I have had to wire the ignition wire into the permanent live feed which means I have to manually switch off the radio.

So does anyone have a wiring diagram for this early version of Audio 30?

Thanks, Peter

You will be missing a switched live an aftermarket radio will require. You will need to wire this in. Most people take it from the back of the cigarette lighter.
