Internal hands free cell phone setup

[OptimusPrime]

Has anyone attempted to adapt a modern hands-free cell phone kit with the stock mic and speaker?

90-96 Q45

A friend of mine is using the following setup and I'm pretty sure it's less than $20!!

Here's the link:

Good luck on your quest.

Ahhh.... I thought I was the only one! No wonder I never heard back from the patent office.

[Rex]

Oh, let's get a group buy going

[Jesda]

Hey dont laugh, Ive done that before!

[rover3l]

yes we could always "band" together but I think it might be a bit of a "stretch"

[Jesda]

Dude, that sucked.

[OptimusPrime]

So back to the point...

Does anybody have any input as to whether or not the q45 cell phone speaker and mic can be integrated with a newer hands free kit?

I understand that it is possible by locating the proper wires and integrating that way, but I want to know if anybody has actually done this.

--TIA

Sorry, for our digressions .

There is a former Q member (now M45) that's in the cell business, hopefully he'll be able to offer some real insight.

I was intrested in the same ideaI wan't to install my T-Mobile PPC in my Q and I wanted to use the Q's built-in mic and steering wheel phone buttons.

Is that what you wanted?

I mean the rubberband thing is cool in all. but I'm a little more high tech.

[OptimusPrime]

Yes it is what I wanted... I want to get a hands free kit but they are all sort of gaudy. If i drove a ford pickup than I wouldn't mind, but since its Q I want to maintain the look of the interior by not adding a wal-mart looking kit.

But...But...I dont have the buttons on my steering wheel. If those could be implemented, could I add the buttons? Where could I get them? I don't see them on ebay and they are never talked about.

[GreenQ45a]

The only real issue is the stock carphone uses it's own built speaker for calls. so if you dont use the stock carphone you'll need to mount a "out put" speaker to replace it. or use a nice car mount that has a built in output speaker.

I'm @ work now I will give more detail later...

That would be me, I guess!

I had one of the original Infiniti phones in my 1991 Q45. Since the search does not seem to find it somehow, I will provide some info on it.

It was a Motorola OEM design, integrated with the audio system (auto mute when receiving and placing calls - neat!). With a rear antenna, remote cellular electronics (trunk), remote mic, speaker below arm-rest (in front of handset). An analog AMPS phone, of course, and service for these cannot be had today - none of the large companies will offer new analog service. About all you can do with that old phone is place 911 calls (this is a legal requirement - any cell phone can make a 911 call without having an account,) although even this is going to change in Feb 2008 when the AMPS service requirement is lifted by the FCC, and all the wireless companies are likely to drop analog in the major cities.

Using the rear-mounted antenna is not practical for new phones, of course, since it only went to the trunk area (where the electronics were). You could screw on an adapter and add additional wiring to the inside of the car to your new phone. However, most new handsets do NOT use a standard SMA or triax antenna connector (almost everybody seems to have a non-standard antenna unique to their model,) so this is kinda useless unless you get one of the car kits which might have such a connector.

In theory, the built-in Infiniti speaker and microphone might be usable with a modern cell-phone if, and this is a big if, all the impedances and efficiency (speaker) and gain (microphone) are similar to what is needed for the small combo jack used with "ear-bud" and other headsets sold today. My primary concern would be if the jack output on the phone had enough power to drive the speaker to any decent level at all - you would need an incredibly efficient speaker to make this practical, and I doubt that the built-in speaker is that way.

Since I no longer have access to my Q45 phone, or any technical info (the service manuals do not seem to cover the phone!), I cannot measure anything to tell you whether it will work. You could try it (handy with soldering iron to make the wires fit into one of the small connector that plugs into handsets!), since it is not likely to damage anything on the cellphone. The soldering would be a bit tricky, since the connector is tiny - find an electronic tech with a lighted magnifier and good fine-soldering skills if you do not want to attempt this yourself. Another possibility is to cannabalize one of these "over the ear" headsets and use its plug and wiring to connect to the wires in the car.

Good luck with this project! My suggestion is that it is more pain that it is worth (but when has that deterred the folks here? ). If you do attempt it, please let us know how it turns out.

I still have 2 Motorola phone manuals.They came with my Q45a

I could send you one.

About the speakers being the output for the phone.

When I asked the dealer about this he said:

"The phone buttons only muted the Bose HU and the other persons voice comes through the Motorola's onboard speaker. So, it must be mounted in the armrest."

I don't know for sure. the guy had never even worked on an Active Q.

Last time I hooked it up for a road trip I never even used it once. It was for backup.

Now I'm wondering if I should call and hook it up to find out.The only thing is my outside ant. is broken off and I dont know what glue to use to reattach it.

I think Wes gave me the pinout for the Bose HU maybe he'll post it again.

It might not worth the time to mess with the old phone system. I've been having the SonyEricsson bluetooth handfree kit for 2 years now and still love it to death.http://www.sonyericsson.com/sp...=9943

They just have a new alternative version now, and cheaper too (about $130):http://www.sonyericsson.com/sp...10141

Less worry about finding a nice looking phone holder and a place to mount them. More talking on the car phone.

Is there such thing as a bluetooth-ready aftermarket stereo? Something that would interface with the phone and mute the audio?

You could gut the dash and stick a mic and speaker in the same location, in place of the factory ones.

I have a hands-free set.

That's not what were after here.

I don't want to look like some wannabe BORG(TM) driving around in my Q.

I want to get a call have my sound system "self-mute" while I answer the call. Then return the volume to its original level without taking my hand off the wheel.

Right now I use the Built in speakerphone

The system is great indoors but add any real wind or music and it will pick that up aswell.

The Q45's Mic is placed after a lot of time an effort was spend to get just the right spot to pick up the drivers voice with the windows down going 55.

That's one hard task to complete.

Sorry my "Phone"is worth looking @.

And this one is a year old.I will be getting the new T-Mobile HP PPC for Xmas.

That one is Bluetooth but I won't be using a BORG(TM) type headset.

Yes, it "wouold be" you and I knew you'd give him a ton of info, as you've done. The question is, as you stated, will the fact that it's more trouble/cost than it's worth deter him .

[OptimusPrime]

I think it has!!!

I did'nt want to make a big project out of it and besides I REALLY DO NOT want to go splicing into any wires without knowing for sure the outcome. I know its only for the mic that is not ever used but I think you understand my point.

Thank you SZHOSAIN and all others who chimed in on this question. I wanted to let the Q45 brains talk me out of it before I laid the idea to rest.

[szh]

I did forget to note one point. You have a 96 Q45 and I believe (but not sure) that the wiring for cellphones in the 94-96 models was a bit different. First, I believe that the wiring was not pre-installed at the factory - they only put it in at the dealer if you got the phone. In this particular car, the phone was a removable unit in the center console and the wiring for the antenna may indeed stretch to there. Second, the "phone buttons" on the steering wheel were new to those years - the 90-93 did not have these. Since I have never seen these phone buttons, I am not sure at all how they are wired into the system!

Regardless, note that the mic gain (I think this probably would work) and speaker efficiency (probably would not work) are still important.

By the way, please do not take my comment about the amount of work to be too much of a deterrent. If you want to take a headset (ear-bud or other) and try this, it might not be too difficult to at least check out if the speaker is loud enough without too much digging - same with the mic. If you want a headset that you can try, drop me a line - I will send one along (I am interested in the outcome of this experiment! )

I took a motorola pager belt clip and glued it right below the rear window defog switch on the dash..... clipped my Motorola V600 in and attached this ..... ....

now I am riding and my peeps think I sittin at home ......

.... You have to adjust, when I first got it I was yelling at everyone thinking it was like a home speaker phone. Just talk normal and everyone hears fine

oh, and $15.

[BigBodyQ45]

No pic of the mic but can take one upon request. Stuck on windshield near stock one. Works fine. I dont think it takes away from the stock look.

[OptimusPrime]

I found a similar kit for my nextel i730. I will go with that instead. It has everything that it needs including the speaker, mic and cradle. I will integrate the newer mic into the stock mic location.

Thanks again for everyones input.

[Q451990]

Do you know if a phone cradle mount like that is available for the earlier Q? I have a Sony Ericsson T226 that I'd like to mount similarly.

[BigBodyQ45]

Not on the site that I can find. Unless it has a similar dash to some other cars and you can jerry rig it
