Hi,
On my W140 S300 TD (1998) WDB 140.135
I noticed there is already a wire installed in the loom that connects to Pin A3 (phone mute colour grey with blue stripe) on the ISO radio connector.
There is no sign that a phone has been installed in the past and there are no antennas to be seen.
Is this likley to be pre-wired for a phone or not?
Where will the other end of this mute wire be located?
Thanks.
