Hi I recently bought the Motorola IHF1000 hands free kit. The kit allows for automatic muting when a call comes in. Is it possible to wire this into a stock honda stereo system?

Car: 2007 Civic Si (stock premium audio)

0ne way or another it can be done, I would not be surprised of your 07 HU had in input that could be used, your hands free kit has a neg.(-) "mute output", correct? 94

The kit does have an mute output. This is what I found on another site. Look at the connector diagram. Any ideas? I have a non-navi by the way. Connector #2 has a TELM and TELMG. Maybe that's telephone mute?

There is a harness I found that provides for mute and audio through the stock front speakers. But they want 140 bucks!

I really just need auto-mute. I don't mine having the audio routed through the included external speaker

is it the unit that comes with a speaker or the one that works thru your radio?

Tam N

The manual says it can do both (it does come with an external speaker). The Si has a stock amplifier though so I don't even want to deal with routing sound through the stock speakers. External is fine with me I just want my mute

Sorry I have not done one yet, [tel. mute] but I would be inclined to think its #5 first plug, marked TEL., but again I am not sure. 94

Whats the worst that could happen? blow a fuse?

The diagram says it has no wire, do I have to somehow rig one up to? How is this done?

http://www.parrotkits.com/donotcut.html This website offers a harness for the 2006+ civic that offers mute for another bluetooth kit. I seems just to be wires, does that mean that the stock stereo is capable of mute? Or is mute controlled by something else?

That, or it just won't respond at all...

Since there's no wire associated with the connector positions you're looking at, you'll need to check and see if there's a pin for that position on the radio. If there's no pin in the radio, you're out of luck.

I would check, [with multimeter] with HU on and off first.

You can probably jury-rig a terminal by stripping half an inch or so of insulation off the same gauge, [or a little thicker] wire as the rest of the wires in the plug, sticking it into the empty pin hole, hold it in place as you plug the harness into the HU, now strip the other end, fold out one strand of the wire, turn HU on, then touch that one strand to ground, cross your fingers and hope it mutes the HU.

The above assumes that, as B18C_EJ8 mentioned, there is a pin in the HU at that position. 94

I emailed Howard at parrotkits.com and this is the info I got.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote"> You wouldn't need my harness to simply use an external speaker. Just have your installer kill the ignition voltage to the headunit or the amp-on voltage to the amp when you get a call by attaching the orange entertainment mute wire on the IHF1000 to a relay. See my support page for how to use a relay.

To mute your Parrot kit: Use the Parrot Yellow mute wire to trigger a relay that cuts off the ignition voltage to the radio or, in an amplified car, cuts out the "Amp-on" signal from your car radio. Most automotive parts stores carry a "Bosch" automotive relay. Be sure to get one with an 87a terminal - ie, a single pole, double throw relay with a normally closed connection between terminals 87a and 30. "Breaking" this voltage line (either to the radio itself or to the amp) will mute the radio during a call. By the way, the Parrot's yellow mute wire goes to ground during a call so it should go to the minus side of the relay's coil (85). The positive side of the coil (86) goes to 12 ignition voltage. The relay should be SPDT or DPDT so there is a connection that can be broken during a phone call's mute. Here is a relay wiring example using a standard Bosch automotive relay: </TD></TR></TABLE>



Im not extremely familiar with car wiring and relays but it looks like something I can do. So I connect my mute wire to (85) but Im confused about what happens with (86) though. Does that go between the 12V Iginition wire going into the HU? How about 87a and 30.

I don't wanna keep bothering Howard over there since Im not going to buy his product. Or do you think I should still find the mute line (if there is any). Any elaboration on the diagram would be extremely helpful. Thanks

That would be one of the other ways to do it, it is simple and effective. 94

Use it on the red wire? And shut the whole radio off and then back on? I thought you just ground a speaker and put it in protect mode. Although I haven't done it that way because it seems crappy.

I'd just get a radio that supports mute, like most of the Eclipses.

fcm

Short out an output on the HU? I would never do that, not even sure if the low current ground output of the hands free kit would be enough to do that.

I have used a SPDT relay, [on the acc. to cut power, I have also used a 4PDT relay on each of the speaker wires neg.(-) leads to cut audio, both are effective and easy to do.

With that said, I would assume the 07 HUs would have a mute or attenuator input.
I have been away from it so long and and just getting back into it and have not done an 07 yet. 94

Tam N

Thanks for the help everyone!

Could someone elaborate/dumb out how I use the relay. I've never worked with relay's before. What goes into each connector as described above?

fcm

If you look at the pix ^^^ of the relay, cut your HUs acc. lead, [probably a yellow/red or purple] check before you cut the lead.

Now connect the harness end of cut lead to #87a and #86, connect HU end of cut lead to #30, [cap off #87] connect the mute output from the hands free kit to #85, [forget about the "12V ignition going to #86, that power will come from the harness end of cut wire that you connect to #87a and #86]
Your done. 94

THANKS! YOU ARE THE MAN! and everyone else that helped. Much appreciated.

Installed it today, everything works perfectly.

Note: There are pins coming from the HU for the unused harness terminals

I'll figure out if it mute is actually there one of these days, looks alittle dangerous though. What would I be using the multimeter to check for? What would happen if it isn't mute and touch it to ground.

fcm

"What would happen if it isn't mute and touch it to ground" POOF!!! you will let the smoke out and you will not be able to put it back in.

The multimeter is to check what is on that unused pin, if it shows 12V at any point, HU off/on/lights on or any voltage for that matter you will not test the pin by just grounding it, [remember POOF!!!].

Test by grounding the pin , but do it through a .250mA fuse, (1/4 amp) if it blows us a 500mA fuse, if that does not mute the HU, the pin is not a mute input, do NOT use a bigger, [500mA] fuse, mute output from the kit will not be more then 500mA. 94
