It might be a silly question, but I just have installed the PX5 head unit, and there are no hazard lights or turn sounds that I'm used to. I mean the lights do work, it's just the head unit does not produce any sound (otherwise it works ok). Should there be sound at all? Which part of configuration should be responsible for these kind of things?

Is it an MTCD/E unit?
Yes, it's an MTCE unit. Turns out speaker that came with the package had to be connected to play these sounds.

hi i have a xtrons PF75AA4A headunit. everythings works great in my audi a4 cabriolet with bose system. i have rooted the unit and installed viper4android so the audio is better than what is was before. The only issue i have with this unit is that the lowest volume "1" is set too high. i would say volume 1 is equal to like 8 or 10 on normal car systems. i cant seem to find an option to lower the volume. if i put the car in reverse than the audio levels go lower but this is cause of parking sensors. Its annoying when im driving and want some ambient music but the lowest volume is too loud.
any help would be appreciated.
the std sound out is fine to power a normal sound system, but the Bose system requires an UN-amplified sound input I have the xtrons in my Silverado with the Bose sound system once I got the AMP powered on I had FULL sound for lack of a better term, then proceeded to cut the speaker out(s) on the harness and added rca male/females to the sound in adapter from the back of the xtrons unit to get sound volume that works. It's been fine since.
quote from a guy on a truck forum
the stock head unit from GM that are Bose the output from the unit to the amp are NOT high level speaker outputs like your regular non-bose head units. instead they are low level rca signals

in Joying in Factory Settings there is a way to adjust volume levels
**** i'm looking for a way to turn it up!
I see that this thread is for lowering the volume, but the fix would be the same if someone needs it to have higher volume by default.
When the HU first starts it always sets the volume to 14 or 15 i think......WHY??? i want it to stay as i left it before shutdown. I don`t think any of the android phones changes the volume when you do a reboot. There are some volume settings inside the "factory settings" menu, but when you change the settings it needs to reboot, and then the problem with no sound and no working buttons comes up, so there is no way to test it, as i have to do a factory reset to fix it.
No wonder there is no restart option by default...
I use my HU with the factory installed stereo "BOSE" with 3rd party AUX unit and i control the volume with my OEM stereo so i need the volume of the HU to be up to the max.
I hope someone finds a fix for this.

it sets it at 14-15 upon boot up to protect your ears.
yeah, i know this but still..... Maybe there is a way of achieving this. Now i remembered that there is as app on the market- "Liama" that you can use to do various settings changes when certain conditions are met. This might do the job.
Any way to keep the volume before the car was turned off. My head unit suddenly gets loud when the car is restarted

Factory settings/other/boot default volume. Default is "no" which persists the volume from last use.

Well my problem is intermittent. Lots of time my head unit would restart with the last set volume... other times it would go to 15
Options
I only have these options in my factory settings

How would you find out what you have and then ask those that have your unit?
Hi Guys, I have a quick question. I was very excited to setup my front bumper camere using F-Cam app which I figure it out while i was messing with Car-126 menu. However due that my unit has only AV input rca, I am not able to get any view with F-Cam app. As far as I investigate, hardware mod is needed to use F-Cam app with front camera. It seems very hard for me, so I want to go with AVIN.apk.
It sometimes works well, sometimes error logo on middle of screen. Is AVIN.apk buggy? Also it drives me crazy that it cuts my spotify's sound when I open AVIN.apk. Is there any possibility to keep audio running in background and show only video in full screen with AVIN?
My unit is a Witson brand PX5 - Oreo 4GB.
I found a similar thread, but it keeps audio instead of video Are there any apks other than native one to use video input of head unit?
https://forum.xda-developers.com/an...-development/help-avin-app-auxiliary-t3466211 (not mtce)
I guess I am the only one who wants to use AVIN app only for camera input then.. interesting.
Where did you find the av-in app?

It is pre-loaded with stock rom already. My unit is android 8.0 px5.
I connect front camera to av-in input of unit, it works but i hate it is taking control of audio.
It is trying to play aux in with video input.
Check all connections on the back. Seriously. You probably have a pin that’s either unlabelled or unused that is really f-cam in. All units should be capable of it, and in a rare case you might have to do some soldering.
Edit: I have a Witson unit as well and it’s the 6th pin on the little 8 pin connector. Pin 3 is GND on mine.
I have just installed an Erisen 7591-HA (PX5) into my 2010 Golf Gti and I am getting static and digital processing sounds through my speakers.
If I mute the head unit there is no static or other sounds.
The digital processing noise happens when playing music via usb and Spotify when selecting the next track.
This is my first Android head deck and I am really disappointed.
Sound is going through an Alpine PDX-F6 amp.
I have tried disconnecting the radio plug and removing the head unit from the dash but no change still has static and processing sounds.
Sound issues remain if the engine is off it makes no difference.
Static and digital sounds do not increase with volume, it remains the same no matter what volume it is at unless the head unit is muted.
Good quality RCA and speaker cable was used.
Any help would be greatly appreciated.
I have the same issue with a Belsee unit I installed last week. Do you have a line-level filter in your harness? I have a theory that the line-level filter that's included in mine is unnecessary, as it's coming straight off where the RCA outs would normally be (and those are line level already, right?).

No I do not have a line level filter on mine.
I have tried using an RCA GROUND LOOP ISOLATOR but this done nothing.
Below is a link to the sound I am getting from the head unit, you will see it only makes the sounds when volume is not muted.

Same issue on my PX5 KGL unit, not tested with filters or similar...
I read somewhere that the LED color-changing caused interference - and I noticed that you have yours setup that way. Have you tried setting a static color? Also, make sure all of your wiring is clean and try to keep any speaker wires away from any power wires (although that is more applicable to an external app setup).
Can you hear the noise at all while music is actually playing? Obviously, it would be better if it wasn't there are all, but if you can't hear it normally (only hear it when nothing is playing), then I wouldn't sweat it too much. All you can do is make sure that your wiring is clean and maybe try adjusting the LED settings and the "pre-amp" settings under the factory menu (maybe see if reducing the "System" setting under "Voice" helps reduce it). Once you try using things like ground-loop isolaters, etc, then there is a chance that the music fidelity is reduced even more.

Yeah have tried all the above and nothing changes.
The sound quality is poor also with higher ranges being really scratchy.
I am sure the unit would be fine if not using a higher end amp and just running the speakers off the head unit, I have read a few posts online and on youtube that the RCA output signal can be really poor with certain brands.
I just sent the unit back today for a full refund and will now be buying a brand name such as Alpine, Pioneer etc etc
https://www.hifimax.net/6-95-inch-android-7-1-quad-core-16g-auto-navigation-gps-head-unit-for-bmw-mini-2006-2013.html
Installed that unit with android 8 4gb 32gb option for a 2013 Mini Cooper Countryman S, installation went quite well, fit is great.
I knew that the factory unit was responsible of playing the vehicle chime and indicator sounds, including the blinker turn signal sounds. Before purchasing a wire harness adapter for bmw/mini that makes up for the vehicle chime/indicator sounds, I thought I'd see what solution this head unit had built in.
Unfortunately, the sounds aren't great. The unit has an external speaker that emits the sounds. The speaker is fine, but the only sound that DOES work is the blinke/turning indicator sound which is absolutely terrible. The blinker indicator tone programmed in is a recording of a classic oldschool mechanical electromagnetic relay switch tinging on and off loudly with a *twang*, lol. The length of the sound file is also too long, meaning it takes time for the sound to stop playing after the turning signal has stopped blinking. Door chimes, key/fob dinger doesn't work, vehicle information notification tone doesn't do anything. Something is strange.
The can-bus decoder seems to be built into the unit pulling from the factory wire harness that is pre-wired. I have no idea where these files are stored, if they are on a subsystem rom that's inaccessible or what but it would be very cool to be able to rewrite the audio files to work like factory. I am up to plugging in the factory unit to record all of the factory tones with some high end recording equipment I have to make it right.
Anyone have any leads of where to begin to correct this?
From my reading the CANBUS external box (which has the external speaker attached) is what is generating the sounds so unfortunately they aren't coming from the head unit itself.

I don't believe that is correct as the speaker is just a 2-terminal connector plugging into the back of the LCD panel module (which houses the px5 processor module, most of the computational components. )
I have the exact same setup and am hoping for a fix...the new sounds are awful and I really miss the key and light warnings.
Hey guys,
since I have changed the sound module for the "DSP" Module, I have experianced this weird issue.
Almost every time when the device leaves the sleep-state by turning the ignition on, the subwoofer doesn't receive any signal. It does turn on, but there's no sound from the sub. It only comes back, when I play with the subs settings. For example, if I mute and unmute the subwoofer, it works again.
Right now I'm running the modded DSP app, but the issue was apparent with the original version as well.
The unit is a Xtrons one. PB7939BIP PX5 running Hal9K 3.7.3. But the issue remained with other versions as well, so I don't think that the problem lies there.
I have read about the same issue from some other people on Facebook, but no solution so far.
Right now I'm thinking of a script that runs in the background to mute and unmute the subwoofer on startup. But I don't know how to do that, I've decompiled the MTCAmpSetup.apk's but it's very hard to understand how it works. So if there is someone who knows how to control the equalizer programmatically, I'd be glad for your help.
Another approach would be a script that does nothing else then starting the equalizer app and touch the mute button twice for you. But that requires some permissions that are basically impossible to get without root, so only rooted users would benefit from it. Also I don't like that approach.
