I'm hoping I can get some answers here about this. I have a Kenwood bluetooth head unit in my truck. I like to use S Voice to text, play music and other stuff without touching the phone while driving.
My issue is if Bluetooth is on and if I say Hi Galaxy then say Play Music it acts if it doesn't hear me. If I turn off bluetooth connection between the Note 3 and head unit then say Hi Galaxy then play music it hears me fine and plays music.
I was thinking maybe the mic pickup wasn't cranked up enough to hear me on the head unit. On my head unit I have a setting for Mic Gain. Is this suppose to increase sensitivity for the mic to hear more clearly? It was set to 0 but I cranked it up to +8 and then tried it again with no result.
On the sound bars, below the microphone button on the S Voice, if sound is picked up it will move up. It never moved so it's not hearing me. Now if I banged on the top of my dash with my fist the sound bars move and shows it is picking up sound but it has to be a loud bang to a point I feel like I'm gonna cracked my dash if I keep on doing that.
I can't tell if the issue is my head unit or the phone itself. Bluetooth volume is cranked to the max on the phone.
Do bluetooth head units have built in microphones? I would think they do otherwise it would be a pointless head unit and pointless to have call button functions on the head unit.
Anybody have suggestions?

Nevermind. After looking over the manual to my head unit I somehow skimmed over the microphone part even though it came with the head unit. I have no clue why I didn't attach it and understand the point for it was to communicate hands free or else the person would not hear me.
Had to take the unit out and install it and it works perfectly now.

Hi, just brought my mum a Eonon GA1312 Android head unit, I've set the majority of it up and brought a lifetime service for Sygic Navigation for offline maps, it seems when playing the radio the directions on the GPS being said sounds like its coming out of a separate speaker or something, this applies to both Google Maps and Sygic, I highly doubt the directional commands aren't coming from a separate speaker, but the volume is absolutely dreadful, you can literally just hear it, I haven't tested this head unit properly yet but I've heard the directions speak out a lot louder while dimming the background music of Spotify, can anyone help me with this problem? I don't want my mum not to be able to listen to the radio while using the GPS Navigation just because we can't hear it. Thank you.
Same problem whit mm y MTCD 3188 and sygic. Sygic nav volume really low. Did I have to mix something in factory setting voice?
same.. does anyone have a solution please?
the head unit have no sense if we can use android app...
Called joying and they told me the audio for the phone bluetooth connection only will come out of the front left speaker on all their units, can anyone confirm this? In my vw the sound while on a phone call comes out of all the speakers. Any car i have ever been in the sound comes out all speakers while on a call, not sure why on these it only comes out one channel if its true.
Thanks to anyone to confirm this.
On mine it comes out the passenger side. I know my Kenwood would allow me to select. I've gotten used to it so it's really no big deal

Yup mine does the same thing and it really sounds bad. It comes out of the passenger side and middle dash speaker, but mostly just the tweeters....At highway speed I cant hear half the call.....I am hoping to find a way around this.
Oh wow OK. I had an idea u had a spare Bluetooth speaker laying around and I can use that in the car but it basically defeats controlling the audio from the dash. This blows my mind how bad the audio is in these. Now is that speaker out or rca out on yours?

No, my current set up is still using the factory wiring harness. I havent had a chance to get my amps and trunk all set up for the RCA outs yet. I am hoping someone smarter than me can figure out a way to change the phone audio output settings.....
I am pretty sure it could be done with alsa mixer but I have no clue how to use it to route audio in Android it's very complicated and zero instructions.

It really is a shame. The phone app is just sad all the way around on this unit. Not having a Favorites list is a another big downer.....and I dont know if yours does it at all, but when I am on a phone call I cannot access anything until the call is ended. Everything gets grayed out even when I minimize the call option on the bottom of the screen....I am pretty sure that is just a bug in the software that will get fixed in an update
I don't have a unit yet myself but at this rate it may be only good for controlling the phone but for that matter I can get a separate controller for that.
On my Joying it does this as well, all of the audio comes out of the front passenger speaker. However it doesn't sound bad. It gets very loud, and I can make and receive phone calls fine. The sound is mono as opposed to stereo, and that does sound weird, but I have no issue hearing calls.
Can people with a non-Joying unit chime in? does it do the same one speaker thing? or is that Joying specific?
In the old days this was common practice so as the speakers didn't cause feedback with the microphone which was most commonly mounted atop the drivers pillar. So the opposite speaker was used for audio
I have a Funrover head unit since almost a week and I have the same issue, sound is coming only from front speakers which make the call over bluetooth just a hell for me.
I barely can hear the caller specially while driving
this is a nightmare !!!
Sofia units use both front speakers.
All PX5, no matter Joying or other units, only use one front speaker

Ok thanks, but that being said, is there a way to remediate to this ?

I don't know. It is already going back to the PX3 models. Loads of topics written about it in the mtcb/d forums. It is best to search there.
phone audio is mono anyway, so I guess they just route it to one of the boxes.
Hello,
I got a very annoying problem with my pumpkin head unit. Theres a noise, like when you place a smartphone close to speaker, which I hear all the time coming out of my car speakers.
Sometimes it's quiet and sometimes I hear that noise.
Is there any way to fix that?
My HeadUnit is (Description from Pumpkin Website):
Pumpkin 7 Inch Quad Core Android 4.4 Car Stereo DVD Player for Opel Vauxhall 2 Din support DAB+ AV Output MirrorLink 3G WiFi OBD2 DVR Steering Wheel Control
I run Malaysk Rom, but had this issues even with the standard ROM.
Would be happy if anybody could help me.
Regards
Ben

It's likely noise from the screen. Try turning the screen off and see if it goes away. It won't be easy to fix. Make sure all your grounds are as good as possible and make sure they are as direct to the battery as you can get. Noise like this is from a bad circuit design. It's the difference between an expensive well-engineered board and some POS from China. Yeah, I got one too, the Lollipop unit (self-rooted w/Viper).
If you only get the noise when the car is running it could be noise from your alternator or plug wires. That's harder to fix. You could use one of the crazy capacitors they make for car audio, but if you aren't running a 1000W, they can be overkill. I would try 1000uF cap across the 12V battery supply to ground, as close to the head unit as you can get it. Make sure the cap is rated at least 15V or so (it will see more than 12 from a car!). It will be electrolytic, so make sure you obey polarity. I'll be doing this myself later today.
May be worth a try running a wire from the negative of the battery post to the radio ground...I would just do it quick and easy in the driveway before trying to route it through the car.
Thank you for your support on that...
Unfortunately that sounds not that easy. I thought this might be a common problem with those head units :-/
I have a sound coming thru the speakers as well kinda sounds like a hard drive reading data when its booting up but goes away once its booted & running.
Might try running a better ground see if that helps.
I got fed up with not being able to understand a word when my wife is driving, with her old Android 4.4.4 head unit. 4 years ago I tried all of the known microphone mods, externalizing the internal microphone and splitting the microphone between the Bluetooth and the internal microphone. It never really helped.
During Aliexpress big sale recently, I got her a px6 (non-MTCD) head unit. The screen and everything else seems to work fine, but the noise when she is talking via Bluetooth is just unbearable. I have tried a few different external microphones, and it sounds like a tornado is blowing in the background. I refuse to start cutting mics again and am just going to return it.
Are there any units out there that have decent sound cancellation? Or is that too much to ask of a chinese radio?
Hey all,
I upgraded from a PX5 Xtrons. Had no issues with it.
When volume is muted, there's no sound. When on 1 or higher, there's a background fuzz. Not static but just a general oldschool hifi 'furry' sound. It doesn't get louder if I turn the volume up. I've tried unplugging everything but the main harness. Doesn't matter if the engine is running or not.
I'm using the Xtrons harness because I didn't want to have to run a whole new one to the boot where the factory amp is. It looks like there's a couple of pins different too. Hoping it's not that...
Any ideas?
Thanks.
Honestly most of these units in my experience have some. WiFi, cell phones, radio etc can sometimes be picked up by the amplifier circuit and you'll hear their resonate frequencies through the car stereo (turn any stereo up loud and put a phone near the active input cable... you'll hear it). Honestly the best thing you can do is make sure the radio is grounded to your chassis directly, that way a lot of these spurious signals are filtered properly and their pesky resonates cease to exist!
Oh and it usually quits when you turn it to 0 because it actually completely shuts down the amplifier...
Thanks for the response. I’ll pull the head unit out at some stage and try and ground it. If it fixes it I’ll report back. Thanks again.
