i have a telematic unit with the ncdc 2015 retrofitted to my vectra c what mic do i use with this unit and what is the 6pin plug beside the 32pin plug does a mic or something plug into that

[TheBoy]

The Omega ones use the Mic fitted in courtesy light. Veccy may be different.

Only needs 32pin plug, and cellulare antenna

Vectra C Mic is in the courtesy lamp as well but it's a different style to the Omega one.

wonder what type of mic it is using for it has to be wired to the 32 pin plug of the telemantic

The Mic just plugs into a loom plug at the Courtesy lamp end

It's pins 1 and 2. The other Mic connection is for a privacy handset.

Close. It is adjacent pins, but its 1 and 17 for the MIC

Pin 2 is the shielding (for MIC). As it runs up the A Pillar, the cable goes from 2 wire screened to just 1 wire screened, thus the shielding is used at that point
