Using factory bluetooth mic with aftermarket radio

Throughout the long history of car audiothe process of upgrading a factory head unit has been standard practice for those who demand greater sound quality, power, and features. It was often the case that the manufacturer installed OEM car stereos were feature-poor, and there weren't many downsides to replacing it with an aftermarket head unit.

The landscape of aftermarket and OEM car stereos is more complicated today, and many owners of late-model vehicles asking themselves the question of whether losing OEM features is worth the trade-off of getting better sound quality from an aftermarket head unit. With the rise of infotainment systems, integration with steering wheel controls and voice controls, and OEM telematics systems like OnStarsimply popping out a factory head unit and installing a powerful new aftermarket one actually can impact or disable a lot of great features.

Infotainment is a portmanteau of the words information and entertainment that means slightly different things depending on the OEM in question. Features that you may lose access to by switching to an aftermarket head unit include, but are not limited to:.

The specific head unit you pick is probably the biggest factor since, in order to keep many features, you have to choose a head unit that has those features and is compatible with the requisite harness or adapter.

Retaining some other features can be a little more complicated, and you will often have to work backward: identify the features you want to keep, find an appropriate adapter unit, and then look for an aftermarket head unit that works with that adapter and that has all the other features and specifications you want. Wiring harnesses are really at the root of any head unit upgrade, and there are a few different ways that they can come into play.

Other harness adapters are designed to be wired to the harness that came with your new head unit, after which they can be plugged directly into the vehicle wiring harness connector. Beyond those basics, wiring harness adapters can also be used for specialized functions like connecting to or bypassing a factory amplifier. On the other hand, if you want to bypass an anemic factory amp and use the built-in amp included in your new head unit, or even upgrade to a brand new external amplifierthere are harnesses designed for that purpose.

Steering wheel audio controls are probably one of the most basic features that you may want to hang on to when you upgrade your factory head unit, and there are a few different ways to go about it. This is also one of the easiest features to integrate with a new head unit, and a huge variety of aftermarket car stereos include some type of steering wheel audio control compatibility.

Replacing a Factory Car Stereo Without Losing Features

In order to retain steering wheel audio control functionalityyou need two things: a compatible head unit and an adapter. The first part is relatively easy due to the prevalence of this feature in cars. In order to retain access to features like factory Bluetooth integration and OEM telematics, like OnStar and Sync, you need a much more complex adapter than one for the steering wheel audio controls, and many of them actually include the ability to retain SWI functionality.

With the correct interface module, it may be possible to retain access to features like:. These interface modules are essentially designed to be plugged into the original factory harness and then connected to a compatible aftermarket head unit. In some cases, you may need to cut and splice some wires to complete the installation, and in others, it is simply a matter of plugging in the necessary harness adapters. In any case, the features that you retain access to will depend on factors like the make, model, and year of your vehicle and the capabilities of the aftermarket head unit that you choose.

If the OEM head unit was only "satellite radio," and came with an external satellite radio modulethen an interface module will probably allow you to integrate it with your new head unit, provided that you select a compatible aftermarket head unit and that the right interface module exists in the first place. The problem of fit and finish can represent almost as large a hurdle as the potential for lost features when replacing a factory head unit.

Aftermarket head units typically conform to the single DIN and double DIN form factors, while the OEMs have increasingly moved toward nonstandard head units in recent years. In some cases, you may be able to find an aftermarket head unit that includes the features you want and that is specifically designed to replace your non-standard factory head unit.

The former is less expensive, and dash kits are available for most new vehicles that include nonstandard modular head units. They can be somewhat complicated to install, depending on how integrated the factory head unit controls are with the dash, but you will typically end up with a relatively clean looking installation.What's new New posts Latest activity.

After quite a bit of time spent researching I determined that I could simply tie the shield and ground together. I gave it a shot and from what I can tell so far it's working fine. I fear there may be a difference in audio quality due to the way I had to wire it but that is not something I am sure of.

Just thought I'd share this for anyone else with the same obstacle. I believe that is due to the pioneer being mono microphone from looking at my jack and kenwood and the oem microphone seem to be in stereo One thing I can tell you for sure is that what I did has left me with poor audio quality.

Trying something different would be advisable. Well I guess im going to go with the pioneer mic I dont know enough about circuitry for combining a stereo input into a mono output. Was hoping you'd come up with something for me to replicate.

You can replicate what im doing, Lol I was hoping someone else had solved this problem by now seeing that I just bought the car, and they have been out almost 2 years The main thing im hoping someone figures out is how to send the 8v or 4v or whatever it is to the camera to get the lines and different angles.Forums New posts Search forums.

Basically, use the 3. In theory, it should work, but I'm not sure if anyone has done this before. I thought I read here of someone doing something similar, but I can't seem to pull up the thread to save my life. I'd much rather do this and have the "stealth factor" vs. I'm using the aftermarket bluetooth with the factory mic, or, I want to see if it's possible. Thanks a bunch in advance. I know someone has done this.

I don't believe it would be too dificult. I've tried searching for nearly 2 hours now.New New posts New media New resources.

Thread starter RedBaron Start date Mar 23, In the ongoing series of adding an Aftermarket Head Unit while retaining as many of the factory accessories as possible, this is what I did for the Bluetooth microphone part I really wanted to reuse the stock microphone, but after perusing the schematics I saw there were 5 wires to the mic, implying that it was an active device - and that doesn't play well with aftermarket head units.

Still I took the mic out from the car and took it apart to see if there was a way to make it work see photos later. There wasn't. Plus, it's only a cheap condenser mic unit, so I decide it was better TO replace it anyway.

Therefore, I decided that the next best thing would be to replace the factory mic, in the stock position, with the head unit's mic; but at least reuse the factory wiring instead of having to route a long-assed microphone wire to Egypt and back i. So, first step is to remove the overhead light cluster unit from the headliner.

This is very easy, just open the sunglass holder and undo the two phillips screws inside. For one thing there are two loose spacer washers on the top of the unit that will fly away and get lost yes, one of mine fell outplus there are two wire plugs lights and mic that you don't want to break.

This picture is the overhead unit from the top, showing the clip and spacer washers, and factory mic unit clipped in place - there's one black clip in front and two grey clips at the back - easy to remove. Oh, and as a tip, once I found the dropped spacer washer, I put a dab of superglue on each of them, and fixed those sucka's back into place so they wouldn't fall out again. Last edited: Mar 23, As I said above, I also took the factory mic assembly apart. So as promised, these are a couple of pics of that.

This is the microphone unit, unclipped and disassembled as much as I could. The white connector shell is riveted onto the black plastic back and circuit board, so there was no way to see the back of the circuitry without destroying it.

But I could confirm with an ohmmeter, that the mic condensor wires are not directly connected to the connector pins, and so is unusable for aftermarket. Great job, RedBaron. What is next, the door switches? And boom. Redbaron has completed took care of my aftermarket conundrum. Thanks for the hard work - It will sure as hell make my life easier when I go aftermarket.Discussion in ' Prius c Audio and Electronics ' started by bigmattFeb 17, How do I use the stock mic on an after market stereo, I've been searching through these forums all day people have been saying its possible but not how to do it.

If someone could point me in the right way that would be great. SinisterSpatula Junior Member. Those instructions are for a Toyota Tundra, I googled the original source.

Hoping someone out there has the info on the Prius C oem mic wires, I'd also like to integrate the original mic on my pioneer headunit. Let me see what Metra said since I submitted my idea. Any word from Metra?

My aftermarket pioneer headunit accepts a mono 2. Would it be pin 5 and 19? Does the factory radio provide the power to the mic on the other pins? So I need to find a 6V source and put that into the Pin 4 and ground Pin 18? If so, did it work? Dylan Doxey likes this. Nate28 Junior Member. You must log in or sign up to post here.

OEM Bluetooth Microphone with Aftermarket Stereo

Joined Dec 1, I'd like to retain the factory microphone instead of running the aftermarket mic up and having it visible. Any suggestions? Joined Dec 29, If not at the radio, possibly in a harness running from the mic to the radio.

I would imagine a plug like this can be found closer to the mic. They usually have a connector just shy of the microphone itself. I don't want to run a new wire all the way up to the headliner though. I have a 3.

I know there is a module in the dash which receives the signal from a microphone, for OnStar. What I don't know is, if there are multiple microphones one for Bluetooth phone usage, and one for OnStar stuff or not, and whether or not there is a microphone signal coming from that module, into the factory radio, or not.

If there is only one mic, and there is no signal from the communications module to the radio, then that tells me that I can likely use dual pairing on my phone to accomplish the task of avoiding installing the aftermarket mic.

If there is a microphone signal to the radio, then I can pop this 3. Joined Apr 19, AFAIK, there is only one mic. And, it should be connected to the Onstar cell phone module.

On most vehicles, the cell phone is part of the Body Control Module assembly. Not part of the BCM, just mounted on the same assembly. RayVoy said:. I had to go back and reread what you want to do. Here is the way I understand that it works.Tags: head unit mic stereo.

Kri New Member. Hey Everyone, I've been browsing through and trying to see if anyone has been successful in using the built in mic with an aftermarket head unit.

My girlfriend wants to update the head unit in her Prius C two. I can't blame her - that unit is terrible to use. It would be nice to get something Android Auto or at least full touch screen. However, the one thing that is amazing is call quality and as far as she is concerned using the built in mic is a must because it picks up so well. We put an after-market Kenwood in my Scion xB and the mic on it is awful and won't mount right anywhere.

The Prius C - perfect. She doesn't want something wired around the car, or sticking out, or that doesn't pick up, so basically the built in mic or nothing. I'll be doing the installation myself, and while I have done a couple of head units, I'm not great at these kinds of things. I've browsed around on Reddit and here and haven't found much promising.

For example, Stock Bluetooth Mic Integrated Into After Market Stereo PriusChat discuss it and shows that there should be pinning in the harness for it, but no one there seems to have completed it. The few cases that have said they've done it are not well documented. Any help is appreciated. Leadfoot J. McCoalroller Senior Member.

McCoalrollerMay 13, I forgot to update this thread until just now. I did the modification described in my earlier post- I bypassed the amplifier and fed the OEM microphone directly to the aftermarket stereo. It didn't sound great. So instead, I modified the housing slightly and installed the aftermarket microphone in place of the OEM one. Sound quality was vastly improved after I did this. My wife likes using Siri via carplay on this deck, and it seems to understand her perfectly.

McCoalrollerJul 14, Bill Reid New Member. Did you keep the stock mic amplifier in-line when you did this? Do you mind sharing the links you researched? I'm in the same boat. I gutted the stock microphone. The mic, amp board, everything. I just used the mounting cage to hold the Sony mic that came with our deck.
