Hi.

I was noticing a partial wire diagram for the PCM 2.1 on this link, was wondering if anyone had the full wire diagram?

My goal/curiosity is if there is a microphone wire to use the built in steering wheel microphone? I have a Dension with the external mic, just curious if I could use the mic's on the steering wheel. Has anyone tried this?

 

hi, IvanRadie, do you have any result? as I am also curious with this.

 

No, unfortunately I never did, and never got any hits to the above, so abandoned the idea. If you do find something though (cause I believe its probably do-able), please share it, I would really like to try this out.

 

When I had my Mobridge unit installed, the installer told me that there is a mic in the factory location but it's not compatible with the Mobridge unit. I assume this applies to the Denison unit also, but I don't know that.

 

did you tried to put the aftermarket microphone at OEM location? a lot of people said the sound quality was not too good......... Is it because OEM has 2 mics comparing aftermarket has ????

 

I'm not sure why it wasn't compatible. I had a mic installed on the windshield, by the rear view mirror. It's hardly visible and it works great.

 

yes, everyone said the behind the rear view mirror is the best location. But I kind of not like remove A pillar cover and wire mike all the way to the center front of the ceiling which might increase future loose parts squeeze noise. Plus, the aftermarket mike is pretty ugly

 

I have the Dension and I wired the mic to the top of the A-pillar, which I find is the best position for audio quality and looks most discreet.

You don't really have to remove the a-piller cover. You can use a thin trim removal tool (some suggested a credit card) and just push the mic cable into the a-pillar cover. Or just run it thru the door frame and hide the cable behind the black plastic weather trim.

Note:
1) unless your passengers need to be in the phone conversation frequently, putting the mic at the driver side A-pillar is better than at rear mirror. The A-pillar absorbs better the ambient noise and reflection of your voice.

2) on the Dension, you'll need to play with the gain-level setting for the mic, but NOT set it too high because it has a crappy mic-amplifier and WILL distort your voice. Try with a caller a few times to get the best result. I set mine to +6, I think.

 

I have my mic wire running up under the drivers side A-Pillar cover and it works great!

 

The mic that I have behind my rearview mirror is almost invisible. It's tiny. The sound quality is excellent and it does a nice job of picking up driver and passenger. If I had it to do all over again, I would put it in exactly the same place.
