I installed a new Android stereo.

Hooked up the rear VES video screen via a PAC CHYRVD

Nothing. Nothing showing up.

I verified that the PAC interface connects their yellow RCA to the 6&7 wire above (yellows to 6, black to 7 under my thumb).

Yet all I get from the VES is:

No way to change that MODE (stays on RADIO).

how did you change the mode before ? from the old headunit i guess,

With the old headunit, I didn't have to change any mode. I popped in a DVD in the old MyGig and the rear VES just played.

it's a power feed linking both mic's, coming from fuse M34,

I am finally getting around to this...the Genlock 610 mirror with two microphones and auto dimming...Ida and other repairs have taken up my spare time. I apologize if this is a bit scatterbrained but I wanted to post this while it was still fresh in my mind.

On the bench the dimming feature works great. I have factory tint so I still have to see how that will affect it. Pin 8 goes to ground. Pin 9 goes to the reverse wire. Pin 10 is also grounded for the light sensors. Pin 13 goes to the switched 12v.

Now to the microphone side of things... Pins 1 (+) & 2 (-) is the OUTPUT for MIC 1. Pins 3 (+) & 2 (-) is the OUTPUT for MIC 2. Pin 2 is the ground for both microphones. The interesting part...at least to me...was pin 15.

Thanks to Nitrogen for pointing me in the right direction. The Genlock 610 uses some kind of phantom power for the microphones. I was not sure how much voltage to apply to Pin 15 - MIC FEED. I found a post on a Ram forum troubleshooting the hands free module and someone mentioned there should be at least 1v on the MIC FEED pin. I do not have that module in my Nitro. I bought it used and it came with a Pioneer headunit and a microphone tucked into the A pillar. My goal here is to eliminate that microphone...I think it looks pretty rinky dinky. I would hate to blow out the microphone circuit with 12v. I played it safe and successfully tested the microphones with 5v. I will then splice the microphone output into the existing microphone cable that is plugged into the Pioneer.

Would anyone happen to know what the proper voltage is for the Pin 15 MIC FEED? On the hands free module that would be pin 1 I believe.

there are 2 maybe 3 possible wiring diagrams depends on vehicles options, did your Nitro originaly come with the Sat Nav option
be careful those pin outs you are quoting for the Mic Feed do not correspond to my wiring diagrams,
if equipped, hands free module is behind right quaterpanel
do you have a microphone in your OEM rear view mirror

I found the pinouts for the mirror online. I do not know what was stock on my Nitro. I bought it used and the Pioneer unit came with it. It has a little microphone that sticks out above the A-pillar. The original mirror was a plain mirror with no microphones or dimming function.

I have tested the new mirror and everything works. I am looking to find what voltage is supposed to be on that Mic Feed line. It works with 5vdc...tempted to try 9vdc and see what happens. The mirror has a 16 pin connector but only has the 8 wires I listed earlier.

i wouldn't try 9volts, my guess is thats way to high, unfortunatly the manual does not give the Mic feed voltage,

I'm currently trying to solve the exact same issue.
Did you ever figure out the correct, expected voltage for pin 15 Mic Feed ?

 

[2ndgen]

Also, what is the factory routing for the wire harness from the mirror? Does it go down the right a-pillar or the left to reach the head unit? Or did it go straight back to the right rear quarter panel for the hands-free module back there?

Found this answer here.
Mic feed is 12V, but only when the uconnect (aka hands-free module) has been turned on.

defnitely worth a try,
