I also bought a car radio on aliexpress similar to yours. Px3 cortex a9 for ford focus c-max.

I have exactly the same worries as you with the microphone, the one integrated in the facade I have to stick my mouth on and scream.

The one who plugs externally is the same thing.

Many people talk about a worry with frequencies that are not the same in china and here

300-3400 for china

50-7400 for others

If you can root your device you can change the frequencies with Pimp my rom.

Personally I can not root it.

Thanks for the feedback. What's the boot time on this thing? Does it have a sleep function similar to Joying units?
[Android Head-Units] stef67000:
About 15 to 20 seconds to boot. For sleep functions, I have nightlight or 15s 30s 1mns ect ...

After trying everything to get the microphone that works for the handsfree kit, I decided to cut the 4th leg of the bluetooth module and solder a mono microphone directly on it. This was my last option because I did not have the c32 connector. This has been a success. People hear me very well now.

Can you try the following and see if this gives you root access:

Goto factory settings and instead of typing 126 type *#hct#root#

This may give you temporary root access. Now you can install supersu or magisk to make the root permanent.

Note: I don't have this device or have not used any other Android HU; so I have not tried the steps mentioned above. I found this on the internet. Please try and let us know the result.

Hello, I bought this unit, but the 9-inch model without buttons and I do not use the search for voice, the free hands works perfectly for me, but for voice searches they do not work with the internal or external microphone.

Nor can I get programs with self-starting like the Radardroid service start only with the start of the radio, I have to manually activate it at each radio start.

I also have no rear camera, only parking sensors, and every time I put the reverse gear turns off the screen and the voice of the radio to try to connect to the back camera even if I do not have it, this did not happen with my previous radio with android 4.4, only with this new one with android 7.1.2.
[Android Head-Units] s.rahus:
(1) In the "Shutdown delay when ACC is off" do you have a new option named "Auto Sleep"?

(2) What is the MCU version you have?

Hi everyone!

I have a similar unit.

I think that the problem is with android version. In our case 7.1.1.

I had a problem with my OBDII reader and I updated my unit to 7.1.2 and fix it

Now with 7.1.2 I have the same problem with microphone and also I have a problem with USB cameras. Only the DVR app can connect with but only the first time. If I close the DVR app and open it again, camera dont work.

I want to use the USB front camera with Mapillary and iOnRoad but I cant.

Any idea?

Where can I donwload a previos android version? for example 5.1.1 or 6 perhaps its would fix the problems.

Thanks!

I've had a Hizpo 7" no dvd with buttons mcu xrc 2.54 android 7.1.2 2gb 16gb for a week. Came this way so I can't say about previous versions.

My bluetooth microphones (both) work fine for me, calls hear me fine. Even just the internal mic seems good.

I haven't had any bluetooth connection problems.

Android does not see any microphone, there is no speech input in keyboard settings, google voice search hears nothing. Voice recorder apps hear nothing.

Tried a usb mic but that did nothing.

Can't get usb camera to work for DVR. RCA CVI cam works in DVR but doesn't record, does not work in FCAM app however, though rear does.

OBDII worked fine when I first tried it, haven't messed with it since.

Display clear and good.

Haven't seen any bog, even when running nav, audio, video etc.

Audio is so so, lots of noise. Radio reception seems great and RDS works too. Needs an amp.

Wifi reception is great, just a little antenna on the back.

I really like it but for the lack of voice search. It's really fast, I have a load of apps and still tons of space. Runs everything so far.

Nearly instant on, radio is playing in under 2 sec (probably 1).

GPS works good so far, finds my location in maybe 10 sec or less usually. I haven't been thru Pittsburgh yet to say how well it keep its signal.

I just got MTCtools and dialer and will start messing with them tomorrow, hopefully I can get a mic input to android and get voice working, then this will be really great!

Bluetooth problem android 7.1

Hello

- I have installed a ELM327 Bluetooth for OBD2, but impossible to pair it while it does work with my phone. do have this problem ?

- your traffic information (with IGO) does it work ?

thanks a lot for your answer and sorry for my bad english.
[Android Head-Units] S@lman1996:

[Android Head-Units] androydgolf:
hello S@lman1996

thank you.

how do i do to update it ? like android phone ?
[Android Head-Units] S@lman1996:
1) you have to download the update file (name starts with px3........) for xda.

2) It will be a 7zip file, so extract .img file to the sd card in your headunit.

3) Go to Settings>About>Software update>A popup appears>Click install.

It will take some time for the update.

After installing OBDII adapter works perfectly.
[Android Head-Units] Flemischguy:
It seems that there are more brands/reseller, like Xtrons, BonRoad, Erisin and probably other retailers, uses the same factory to build the exact same radio and putting their own MCU layer to it, so it is not compatible with eachother. And why back to an old 32 bit quad core CPU that's slower (1.4ghz) than the original RK3188 that runs on 1.6-1.8 ghz, even the gpu is reduced in speed.

Hi

1.Can you tell me where are updates for download for BonRoad Android (I have 7.1.2 version )?

2.Any docs/tips for hard reset (RST hole, how many seconds to wait,....steps...)?

3.Factory settings -any info (key study, CanBus,Other)?

I have changed Factory settings/Voice and set Sys to 20, DVD and Radio to 0. Now the voice from nav.app Sygic/Here is loud (mixed with radio music).

[Android Head-Units] aeidian:
Has anyone managed to obtain root on these 7.1.2 units? The method for the earlier versions of android do not work and Kingoroot won't even run when installed. I'd settle for a downgrade to a previous version of android but I've yet to see anyone offering a way to do that. I've tried renaming dupdate images to nupdate and flashing them through recovery but it just tells me invalid firmware. I found a post one of the devs gave a test version of 7.1.2 to flash from a previous version of android, then an nupdate file to flash back to the previous version but that doesn't work for me to downgrade from my unit that came stock with 7.1.2, it starts to flash it but then kicks a bad parameter error and then gets stuck on the boot screen and recovery became inaccessible. Had to use a specially flashed sdcard to even get it to error and stop the boot so I could then reset and get into recovery. So far all I've found is that we can flash other versions of 7.1.2, but not downgrade, unless someone else knows something I don't.

Is the android picking up your microphone? For me, the microphone works beautifully during Bluetooth calls, but otherwise its not even picking up any sound. I tested by installing voice recording apps, but nothing is getting recorded?

Hello. I am new to the forum.

I bought an 8" Android Head Unit (ROCKCHIP RK-PX3 Android 7.1.2 Quad-Core 1.6GB 2GB RAM DDR3) (MCU STM32F091VCT) from Isudar at AliExpress and I wonder if it will work with a 4G Huawei dongle (E8372h).

Everything works like a charm except I have some kind of "problems".

The sound is not too loud as the original VW RDC310 and I have connection problems with the OBDII (It doesn't connect to the car ECU).

The unit has shipped with 7.1.2 version of Android.

Any help?

Also i have installed Spotify on my radio and if i get call whilst i am listening to it then the Spotify will continue playing in back ground silently and will not pause and when i finish the call it will carry on playing with some next song, does this happen with you? Same thing happens when i am doing parking and when backup camera option comes up all dough i don't have one.

I was going to put external mic on it to see it makes difference but it looks like it doesn't or have manage to solve it.

Also when i go to stream wheel key config there is notting there, is this same with you or its just me and all though i have notting in that list i still has volume control working.

Hi Guys,

When I navigate to "Steering wheel keys" and press any button to bind the steering wheel keys to new function, nothing happens. The default steering wheel controls are working. Any one else has this issue- are you able to rebind the steering key functions?

P.S: I have a VW with Canbus.

Cheers,

Rahul U S
[Android Head-Units] tbmiso:
I have the same question
[Android Head-Units] s.rahus:
Your car has Canbus?

From what I understood, I guess the steering wheel key "learning" is not possible in cars with Canbus. You can disconnect the Canbus and make some wiring changes (connecting Key 1, Key 2 ) etc. and some more stuff) and make it work. However then you will lose all the fantastic Canbus functionalities. Anyway all steering keys are working as they should just that if we want to change the key binding then its not possible by default (one may try MTCDtools, though).

Thanks,

Rahul U S
[Android Head-Units] tbmiso:

[Android Head-Units] themiracy:
Ahh, you guys explained several things I couldn't figure out. :D

Has anyone solved this problem yet? There is a setting to allow audio to continue in backup (so the screen goes black, with the hazard icon, but if you're listening to something, it continues), but the solutions I've found referenced for other head units like this, for this issue, require root - e.g. to delete the MTCBackView.apk file from /system/apps - I don't think this can be done without root?

[Android Head-Units] rohitbaba:
Hi

For those who want to disable the black screen when reversing this is how it's done.

Go to settings 》 factory settings 》 on top right corner go to other 》 go all the way to bottom and find *Prohibit reverse* and put option to *Disable* 》 click apply 》 exit.

The system will ask for reboot so say yes.

If you don't get reboot option and still getting black screen when shifting gear to reverse then manually reboot system by holding on to power button round button which located below number 1 - 6 and up on reboot that should be fine.

Thanks

Connected to back-car (brake ctl) brown wire for trigger and to ccd camera rca connector.

When i put reverse i just have yellow warning sign.

Difference is in wiring for camera power.

Same wiring diagram worked on previous camera with the same camera.

Please, does anyone solved this?

Hope you are tapping the power for the camera from the reverse light?

For camera power:

tried with reverse light (trunk closed),

tried connecting just red wire for power with red wire on chinch connector (rca) as shown on wiring diagram in my previous post.

Nothing worked, even ordered new camera an tried - still no picture.

RDS function

Hi guys,

I bought a radio (on aliexpress / as new member i am not able to post a link here) with the same OS/SW (new4_PX3_7.1(20171227), latest SW

The seller it not answering my questions, therefore I would like to find answers here.

I think that AF functionality (of RDS tuner) is not working correctly.

Situation (I am driving a car):

-	I have stored radio station (e.g. BBC) in a memory (P1)

-	Radio shows station name on P1 button

-	The AF is turned ON

-	When the signal become poor, the tuner start for a scan but in some cases it's not able to find an alternative frequency (probably in the case there really is no alternative frequency at that place)

-	So I tuned another radio station

-	Later on the name of the “BBC” disappear from P1 button (I see frequency only)

-	Than, later, on the place I am sure BBC can be tuned, I press button P1, radio switch to that frequency, but there is only noise (I understand). Even after some time, radio does not start find alternative frequency (I expected radio to start automatically find alternative frequency, but it doesn’t )

-	But when I manually initiate searching radio stations, I am able to find it (on different frequency)

My question is: - is this proper functionality?

Another my question? Is it possible to install another tuner application (which I hope will works better)?

Thank you in advance
