PX5 MTCD/E Head Unit Discussion Thread [Rockchip PX5 A53 | Android 8.0 | 2/4GB RAM]

Could you elaborate on what you went through to get lanewatch working? On mine it just gives a screen with a yellow exclamation point...

Yes to get lanewatch working you have to make sure the user version is set to version 2. This is in factory settings in the other tab.

This picture should show how to get it.

I have already contacted them but waiting for reply. The wiring is plug and play so I doubt there any issues but I going to get the unit exposed to test over the weekend.

If you don't mind since we are of same ride. Can you see the setting for canbus under factory settings. Is it honda_crider?

Cheers

This picture should show you all the info about my canbus to see what is off on yours. I'm not sure if you have the same driver side as me, it looked like you had driver on right I am in US so some settings may vary slightly.

 

[typos1]

I have attached the MCU version.
Hope you have some advice

Cheers

Try recalibrating the screen in factory settings.

Hi all, today I received a tempered glass protector I bought and it fits perfectly on my 9" XTRONS PE98MTVPL.
Bad luck I scratched the screen before receiving the protector.

If anyone interested I bought it here: https://www.aliexpress.com/item/Vehemo-Tempered-Glass-9-inchs-198x112mm-for-GPS-Ultra-Thin-Guard-MP4-Player-Transparent-Screen-Protector/32852696117.html?spm=a2g0s.9042311.0.0.74624c4dSUHO1L

No this Is not normal! This happened to me as well and after a day my battery voltage was too low to turn on the engine.

I went back to the guy that installed the head unit and he fixed it. Needless to say that I damaged the battery that was already old and I also had to replace it.

Hello all,

I tried to read as much as I could, but I still didn't understand a point: what is the main difference between MTCD/E devices and the "others" (like Joying)? In terms of benefits/deficit, etc.

I have a Passat Variant B7 2014 and I'd like to buy my first Android unit. I like Dasaita (I understand searching around that is maybe the best choice: for support, updates, quality in general), but they only have a model (9", that is good!) with 4 physical buttons (HA2137-V840) and I'm not really sure it would look good in the car. I like the physical buttons in the car environment, because I think avoid distractions, are easier/faster to switch between the main feature d the unit, and keep the car's style. So I'm looking around, since a while now, and I'm really confused :/

I saw the Joying JY-VO130P4 (and I read in this thread that is not MTCD/E), but I don't like only 2 USB ports and not detachable, TDA7388 (also here I'm not sure if I'd notice the difference with the TDA7850/1) and the seller on AliExpress told me that the physical buttons are not re-assignable (is it the same for all the brands?).

I'm looking for other brands, with similar specs, Xtrons (PB88UNVP), Erisin (ES8805V), Eonon (Ga9153A), etc., but what is the main difference between all of these? I believe the support/updates, am I right? There's more to look for? What are your advice?

Sorry for the long post, but I'm seriously confused

Hello!
Use the following instruction to receive permanent root on Android 8 using adb without flashing device:

1. On Head Unit, install terminal emulator on device and run two following commands and reboot device. This will open ADB witj root permissions on the port 5555
   

   setprop persist.adb.tcp.port 5555
   setprop sys.rkadb.root 1

2. On your PC, download latest "SuperSu" zip archive from official site, extract su binary from arm64 directory inside the archive
3. On your PC, create new file called "rooting.rc" with following content:
   

   service rooting /system/bin/su --daemon
       class main
       priority 10
       user root
       oneshot
       seclabel u:object_r:system_file:s0

4. From your PC run:
   

   # adb connect "device_ip"
   # adb root
   # adb connect "device_ip"
   # adb remount
   # adb shell setenforce 0
   # adb push su /system/xbin/su
   # adb push su /system/bin/su
   # adb shell chmod 06755 /system/bin/su
   # adb shell chmod 06755 /system/xbin/su
   # adb shell /system/bin/su --install
   # adb shell /system/bin/su --daemon&
   # adb push rooting.rc /system/etc/init/rooting.rc

5. On Head Unit, install SuperSu from PlayMarket and ask "NO" when application ask to update the module
6. Reboot and enjoy!

First off, thank you for the rooting method for the PX5! I'm surprised to see so little traffic on this topic. I ran through the process noted without too much trouble and was able to get SuperSU installed and ES File Explorer working in Root Explorer mode. My main goal is to get Viper4Android installed however it sticks in a root approval loop when I try to install sound drivers. Some manual instructions for V4A suggested I needed busy box as well, however, when installing it gets stuck in the same loop saying Granting Permission for Interactive, then sits and says the same again and again. Seems there may still be some restrictions going on. SU also kept wanting to update the binary, so in final effort I did and after reboot I was stuck at the boot logo screen. Reboots and clearing d-cache didn't help, so I ended up just reapplying the same system update from the boot loader and that brought it back but without root.

That's where it's at the moment. Thought I'd post here to see if anybody had ideas before I go at it again.

As an aside if anyone has an idea of how to get V4A on the PX5 without the side root hassles, I could probably skip the rest.

Thanks everyone, great community!

Your unit is not a mtcd unit...but try by yourself the rooting method.

Thank for your reply, it's disappointed that I'm not an expert to try rooting by myself.
Could you know there's any method rooting for this kind of HU?

Can anyone help me with this?

What is the main difference between MTCD/E devices and the "others" (like Joying)?
There's much difference between TDA7388 and the TDA7850/1?
The physical buttons can be remapped?

I'm almost buying the Joying JY-VO130P4, but I'm not sure.
I'm looking for other brands, with similar specs, Xtrons (PB88UNVP), Erisin (ES8805V), Eonon (Ga9153A), etc., but what is the main difference between all of these brands? I believe the support/updates, am I right? There's more to look for? What are your advice?

I'll be glad for your answers. Thank you.

I dont think.much difference between both chips...
Joying is a complete different hardware than mtcd units, even having same coreboard, the motherboard and mcu are different...and hence they are not compatible to mtcd rom (like malaysk)
Eonon, Erisin...not very reliable support (as per users comments).
Xtrons good support
Dasaita good support as well

thank you ikerg. i like dasaita, but they don't have a unit with physical buttons (like joying, xtrons etc.) :/

i'm not planning to change rom, so, excluding this, there are differences? will you suggest to buy this joying unit (or joying in general)?
do you know if the physical buttons can be remapped (in these units with physical buttons in general)?

I watched a video in which physical buttons were remapped in joying units...so yes.
I encourage you to ask opinions for joying users.

Alek, I'm not sure specifically what vehicle you're looking for but from you Joying P/N it looks like Dasaita's got several VW units with physical buttons... http://s.click.aliexpress.com/e/b5P2CFkk

I do prefer having bigger screen than useless buttons.

hello WranglerRestyle, I saw the models and they actually have a nice 9" model but with only 4 buttons on the bottom, and a 7" model "VW style", but I don't like it too much and is maybe too small the screen. I have a Passat Variant B7 (2014). The 9" was my first option, but then the seller told me the buttons can't be remapped (I was thinking to give a short and a long press function to the back and pwr buttons, to increase the functions), and actually is not much like the car style.

the buttons are not useless from my point of view, on the contrary I find it very safe (while driving. a touch screen can't give you the "feel feedback", so you need to watch the screen), easy to switch between functions (phone, radio, navi, etc.) and more reliable. Moreover, is very like the car style.

Thank you for your opinion guys. Anyway, I'm still very confused. I'll maybe wait a bit more before to decide what to do.

 

[WranglerRestyle]

Good luck!
