Any radio wiring experts know what "Detent" leads are for?

I'm installing Bluetooth in my 2010 Sedona using a stereo from a 2012 Sedona. I've got all the steering wheel wiring and microphone sorted out, but there is one wire that has me stumped.

The wire is labelled "Detent" and is a green wire on the 2012 harness, but there isn't one in my 2010 harness. The differences in the harnesses are the 2 microphone wires, and the one wire labelled detent.

I'm guessing its to prevent pairing devices unless the shifter is in park, but can't find any info to confirm. The reason I'm guessing that, is my Elantra won't let you pair a phone unless its in park.

Here's a diagram (not mine, i don't have the infinty sound system) as an example of the "Detent" labelled lead.

Maybe, but you'd think that would be info that goes over the network, not a discrete wire.

just guessing?!

Speaker Phasing Each speaker has a (+) positive and (-) negative terminal. Placing the (+) positive speaker terminal to the solid color wire and the (-) negative speaker terminal to the stripped wire is very important. Connecting these wires correctly is called "In Phase". Placing just one set of speaker wires backwards causes "Out of Phase" speakers. What is the symptom of "Out of Phase" speakers? Lose of bass! How do you test for "Out of Phase" speakers? There are two tests! Listen to the audio - Place the bass at the highest setting, turn the volume to a moderate level, adjust balance and fade to one speaker. Listen to the bass, balance to the opposite speaker. If speakers are out of phase, you will loose bass response as you balance through the center detent and bass will return when one speaker is on. Then fade to one speaker, listening to the bass. Balance to final speaker listening to the bass. If you have access to the speakers - Place a "Flash Light" batter across the speaker contacts, the speaker cone will jump forward away from the magnet or in toward the magnet on the speaker. When the speaker cone jumps away from the magnet, recongize which terminal is attached to the (+) positive side of the battery, this is the (-) positive terminal of the speaker.

My Google-fu didn't come up with much, but it might have something to do with remote volume control.

My WAG would be power antenna.

you might ask theses guys. help

It's in and everything seems to be working without that wire connected.

I need to put the interior back together, but it's connecting with the phone and the microphone and controls all work.

I do know that newer cars are required to limit Navigation and iPod/MP3 function when in gear, so I would imagine you're correct with the shifter idea.

I'm pretty sure it would have to be an optional wire. Otherwise, the manufacturer is limiting their customer base to just vehicles already wired for it.

In reply to curtis73:

It appears I am wrong with the shifter idea.

I tested by trying to select the pairing function while moving, and found out that the radio speaks to me to say that "function is not available while moving".

Everything works and it gives SWMBO handfree calling, BT streaming, and steering wheel controls so I'm going to assume it was for some other function not present in the van.

If anyone else has a 2010 or newer Sedona that they want to add Bluetooth and maintain the factory appearance, I can provide the details and parts needed for the install.

It was approx $300 for parts, and looks like it came from the factory with BT. Call/sound quality is excellent with no noticeable road noise, even when traveling over groomed pavement.

I used the following for the factory looking install:

• kia factory stereo with Bluetooth and Sirius ( salvage yard was nice enough to leave 6" of wiring and connectors on back of radio)

• a new microphone (used vin from Carmax website to get right color)

• used steering column to get steering wheel radio controls and harness that connects radio and cruise buttons to clock spring.

I'm not sure if the 2006-2009 have the wiring in place in the harness for the steering wheel radio controls, but if the wiring it there then the install would be the same as mine.

Not required, AFAIK. A number of manufacturers do limit it, but my 2016 Audi will let you access all the usual functions when in gear/driving, so long as you click through the lawyer message.

FWIW, my diagram labels that circuit "Auto light in" and it goes to the instrument panel module.

I will see if we have any information on that work tomorrow, looking at the harness it looks suspiciously as if it were built by Blaupunkt.

Thanks to everyone for their suggestions.

Everything's working, so I'm leaving that wire out.

Detent is defined as a machine that prevents motion until released.

My research on KIA radios shows that if dash light illumination is low, detent is off.

Ergo engineers are morons.

Detent is what you stay in when you can't afford dehotel.

The speaker test is only half right. Technically you just want all the speakers doing the exact same thing regardless of which way they go to be in phase

N Sperlo is correct. It is related to the illumination circuit, which uses three wires on that car! The others are more obvious, 2 and 7 on connector A.
