Any ideas where is the wifi antenna? In bench-testing mine, wifi is slow and it drops connection a lot. I'd guess they have GPS or radio antenna sharing wifi duty, but not sure.

I bought an Android Auto Head unit (ca7023), it has Wince system, but no nav, no way to enter windows system too. But sound is low, in this internals it have an yd7388 and 2200uf caps, I will change to tda7854, in datasheet this is pin compatible too, but double the watts. What caps mod do? change 2200uf to 10000uf? It raise temps of amp too? I have standard speakers, My older stereo have 60wx4 mosfet amp, maybe an pa2030a I don't know but are much better, I only change because android auto is a must to travel and city.

Hello Guys.
I'm new to this forum but I have been dealing with an annoying issue with this equipment ZXDZ-01.

I bought one ZXDZ-01 Android head unit 2GB, 16GB, Android 10 and install it in my old BMW E46.
The issue is everytime that I connect my phone via Bluetooth to the unit and share music the music is constantly being cut. Cuts may even during some minutes then return the sound. While it cut music still continue to proceed. The same is happening with hotspot. I installed an app with Portuguese Radios and share my phone's Internet, but it runs with cuts many times it's such annoying.
I already turned off phone's WiFi, try to change Bluetooth codecs, put all of bluetooth related apps and services out of battery saver but nothing resolve this issue.

Are there anyone that faces the same issue?
Could anyone help me?

Thank you so much 👍

Hello, I have this same central and I'm having problems connecting the Zlink. after doing a reset, zlink stopped working, asking for an authentication that I don't know how to do. I do not have the requested key. I call the internet and it keeps giving the same message and not doing the mirroring. Does anyone know how I can get the code to validate?
Tnks

Hi there Leonardo, where did you connect that module (max4466) it's supposed to be a microphone amplifier. Did it REALLY improve the audio calls?
Also, your microphone is in the ceiling of your car or in front of you?
Thanks

    HI there..

    I have a Chinese made Android Head Unit running Android 9. The brand is called ZXDZ_01 Car Navigation Head Unit. What I realized is that this head unit doesn't have audio panning (panning front and rear) as left and right is available. Is there any way I can install a 3rd party app or configure to have that function enabled? I've tried Alpine TuneIt app (the UI got enlarged at some point which I cannot access other UI options), I've tried Poweramp app (this app somehow sucked on volume adjustment which it sounded really lame), I've tried Noozxiode EIZO-rewire PRO (this app really didn't do much).

    Aside from that, the Head Unit has an update via OTA, downloaded it but failed to install (it popped out Error with the Android robot laying down). Attachments are given below. In addition to that, I stumbled upon a page within the Head Unit that it says 8227L_demo before I renamed it to a specific name for identification for device connection.

    Though it's a Chinese brand, it sounds really good actually with the absent of the fader option BUT I do prefer to have the front and rear fader option as I don't want the front speakers to handle the audio output similar to rear ones as the rear ones are capable to handle the output (kinda like a F 30% - R 70% audio output bias, give or take).

    And, this unit is kinda slow (touchscreen and touch button). With MTK processor and 1GB RAM and 16GB Storage, the specs sucked I know BUT if you guys can help/ advise me on getting it to run slightly smooth, responsive AND most importantly splitscreen capability is suffice. Good thing WIFI ok nonetheless it's slow, GPS is ok.

    Device description below :

    Model : ZXDZ_01

    Android version : 9.1.0

    Android security patch level : July 5, 2018

    Kernel version :
    3.18.79+ (gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05))

    MCU version : CVD1810-WJ_19.08.22_309

    If any of you guys can help, I really appreciate it. Thank you.

    Pass for factory settings probably is: 8888
    A little disclaimer: If you change the boot logo to something with a wrong format you risk bricking the unit...
