Chinese Head Unit ZXDZ 01 (8227L Android 9) Query

Sounds really good???
So you don't hear any noise in quiet parts of a track if you play at low volume with engine off?
I guess speakers with high sensitive would make the static noise more obvious. But I find it so bad that I think it would be quite obvious with normal oem car speakers.

I am using JBL component speakers and I don't hear any hiss. however, the sound quality overall is bad in this system and I suspect a software issue rather than a hardware issue.

My ZXDZ device dont have google services, in settings no account settings etc. I don't know how install google services, play store etc? Downloaded apk's but crash everything. Flash Tool can't see the HU. I have no idea what to do anymore. The seller did not respond. Any idea?

 

[mt_nik]

With which application can control the sound of the rear and front speakers?

Please answer me, If anyone knows.

well, there are apps for installing Gapps on some Chinese smart[phne, that app should work for you too. Google is your buddy. good luck!

Van ilyen fejegységem, telepítés után jól működött.
Az autó feszültségmentes lett, és most újraindul, és jelszót kér. Nem adtam neki sehol jelszót. Körülbelül 30 fajtát próbáltam ki, de semmi sem oldja meg. Valahogy vissza tudom állítani a fejegységet a gyári alapértékekre?
Vagy mit tehetek?

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.

Guys, the reason your unit doesn't have EQ or fader is that it's missing an audio chip. Older units all had it, like YT9216, YT9217, YT9218, and even (older) YT9213AJ. If you buy Android 8.x or 9.x then the audio chip will be present.

See the pictures below explaining the issue.

The audio chip is TDA7729 (TDA7719 , CSC37033 , SCS37534).

Now there is a fix but it requires advanced soldering skills and a proper setup.

Sorry to be the bearer of bad news.

I've got same unit with updated firmware. I bought power player pro to get eq control, works perfectly in my Benz. Don't need fader so never bothered.

Please answer me, If anyone knows.

The soldering actually doesn't look too bad, I've done a lot worse.
Is there an actual documented fix thought? Looks like it might need more than just that chip. I see some capacitors, transistors, etc. missing as well, so it looks like it needs that chip and everything connected to it.

Google Translate doesn't really do a great job with that, but I guess it's probably not worth the effort considering a better one isn't that much more expensive.

I speak Russian. I might translate that post and share it on XDA, seeing as all of the newer units are missing the audio chip.
