X920BT; mute from external source?

[Gregscalade]

I just got my X920BT and will be installing it this weekend. I plan to mod it such that the DVD, nav menu etc are accessbile during driving.

 

My question is how do I (or even, can I) wire the unit such that it is muted when an external device goes off and the ground wire / circuit on the device is closed? Can I tie that wire into the X920BT such that it mutes?

 

Thanks for the help

I guess that my question, stated more clearly is as follows: If I install a pin & wire next to the yellow wire (over one spot) to accomodate the GPS/DVD enabling at all times, can I still use the stock yellow wire to connect to an external device such that X920BT mutes when the circuit is closed to ground?

Just insert a new wire instead of pulling/moving the mute wire.

What exactly are you trying to do?

[Gregscalade]

I have an external device, similar to a radar detector, that has ground wire/circuit that switches when it alarms. I would like to hook the device to the pioneer, such that when it alarms the stereo mutes. I assume that I can do this with the yellow wire?

However, I don't want to lose the ability to use/play DVD/gps at all speeds.

So can I use the stock yellow wire as described above and install a wire next to it to achieve gps/DVD capabilities at the same time?

You will need to use the mute wire for the "other device" purpose and use a different wire for the bypass. Are you going to be using any amplifiers?

[Gregscalade]

Yes, two amps.

[VBLUE42]

Tap the amps remote into the 12 volt switched wire and use the remote wire from the unit as your bypass wire.

[Gregscalade]

I don't follow.

Rem turn on for amps should come from blue & white wire from head unit. The remote wire from my detector should connect to yellow wire, and I should install a new wire next to yellow and connect to ground?

What I wrote will work as I described.

[Gregscalade]

Ok...but I don't follow what you wrote?

[VBLUE42]

Well what part do you not understand?

[Gregscalade]

I guess that you just threw me a curveball talking about amp connections, because I thought that was standard practice.

 

So to clarify:

1.) rem turn on goes to amps per a standard installation

2.) mute wire goes to my external device

3.) new wire installed next to mute wire goes to chassis ground.

 

Is that correct?

 

 

Also, since you seem quite knowledgable, do I really need to hook up the VSS? If I don't, what will I lose?

 

Thanks for your help

[VBLUE42]

What is rern and yes? And yes, connect the VSS if you want total GPS accuracy. And re-read what I suggested. Don't try to make sense of it, just do it.

instead opf moving the mute wire with the 920's because of how difficult it can be to remove it, i have been inserting just a small piece of 18 awg wire into the empty pin and using a little glue to hold the wire in there
