Hello

Just a question:

Did you ever try - instead of soldering - to attach the mic to A19 and A20.

I am wondering if the unit will recognize the new mic and switch to port A19 and 20

Regards
[Android Head-Units] sheshman:
yeap, in my case didn't work, but you need to consider that this unit has lots of copies,i mean for example on my head unit parking lights(when you switch on the parking lights the car on the screen turning lights too) works on green cable, but for some people's head units it's brown or blue cable, so maybe it can work on your head unit,it worth to give it a try.
[Android Head-Units] wooldogsinc:
I don't even have A19 and A20. On a side note anyone notice the unit heatsink gets very hot. Any ideas to cool it down?
[Android Head-Units] sheshman:
This head unit has two versions flat one and fat one, which one do you have? That's what heatsinks does, that's ok.

Hello!

I have a navigation 9" with 1 GB ram, even in picture is show 2 GB ram.

I am not sure what version of firmware i can use because in navigation info is YT9216c.... but if i use a android apk i have YT9218 (please see below)

I have problems with audio:

1. the function of HIFI is auto closed after 5 -10 seconds when I start the car, if I select again HIFI will keep until next engine start.

2. radio fm apk is "stupid", no RDS, no favorite, and bad signal, I found that I have chip 6625, and on this forum I found that this chip support RDS.

3. problem with volume, when I am on radio fm the volume even is at 1 is too loud.

From what i read on this forum (I have 2 weeks of reading) solution is to update the firmware and if is possible to be a rooted version to have access to install other apk radio and equalizer for sound.

Can someone to help me with a firmware and with support I am not a "hacker" and I asked in my town help (to pay for update but nobody answer me )

Can't upload pictures...

There should be a sticker on the side of the white connector, on the back of the HU, that will tell you if you have a 9216C or another.
[Android Head-Units] wooldogsinc:
This is the radio app switching off HiFi. Update your firmware and radio app.

Yes it is stupid but there are solutions that will enable RDS.

You can change volume settings in factory settings.

There is a pre rooted version available to download on XDA forums. I am sure you have come across it if you have 2 weeks reading.
[Android Head-Units] Blefish:
After being on the forums for a few months now, it seems like any ROM is good, just make sure you only flash boot.img and system.img. It seems like the software part is compatible, only the lower level bootloaders needs to be matched (I think it has something to do with different chips and RAM layout).

I am still fiddling with the firmware, Smali is quite straight forward but I had not managed to test my change. For YouTube I recommend YouTube Vanced with microG (this allows you to disable Play Services for more RAM and better performance, at least on 1GB variants).
[Android Head-Units] ciprikbv87:
There is no sticker,

For that i start this post which info is real ?

After the update the touch does not work and the physical buttons do not work

what is the solution
[Android Head-Units] sheshman:
it's hard to say anything without knowing what you did before this happens but a reset would help, there is a reset pin under the microphone (at the up left corner),use a toothpick to reach the button and click reset button, let it boot again and it will solve it.

If it's not solve your problem then you need to flash a ROM

I can't for some reason update to the Firmware 20190906

It just says incorrect version when I try to update, and it doesn't recognise it when I reboot with an update folder.

I am currently on the 05 version which is draining my battery which is why I want to update.
[Android Head-Units] sheshman:
i'm using 20190906 and it has the same problem, killed my battery in 2 weeks, so i went to my mechanic and he added a relay to system, when i take out the ignition key head unit shutting down (relay triggering and it's cutting the voltage) when i put ignition key again relay releasing the voltage and head unit booting up, since two months i'm using like that and didn't see any problem, only thing is booting takes like 1 minute so you need to wait.
[Android Head-Units] Matchless 2015:
This does not sound right.

The proper connections of the red (ACC) wire and the thicker yellow (+12V) wire should correct this.

The yellow wire should be connected to a wire from your cars radio fuse that has permanent +12V on it regardless of the key position.

The red wire should be connected to the Accessory wire from the car the only puts out +12V to the radio when the ignition is on and in some cars also while the key is off and not pulled out, then if you pull the key out the radio switches off.

On some forums people have reported that a few of the Chinese radios had these two wires reversed in the adaptor wiring, but I have not seen this myself.

Connected properly like this the radio should boot up quickly when the key is inserted and turned on.

You can measure the current drawn by the radio with an ammeter in the yellow wire, about a minute after switching the radio off the current should drop to about 10mA.
[Android Head-Units] biker_955:
I have checked and wired the acc to a SWITCHED supply. But it still draws 2 AMPS all the time.

[MENTION=7074464]Matchless 2015[/MENTION] It does switch off the screen when the key is removed and startup when back in ACC position. Startup is a WARM start straight to the launcher until the battery gets low then it goes to cold boot with Android startup screen.

[MENTION=6105230]sheshman[/MENTION] could you give me more details on how you wired the relay, is it only to the yellow wire or the red power wire

EDIT:

OK just went and checked, been off for over two hours now.

Red wire no voltage since key out.

Yellow wire 12V taking 500mA at the moment.

Rewired so both are wired to the Acc feed so it always does a full boot now on power on, but doesn't drain battery
[Android Head-Units] Matchless 2015:
You most probably know this and are doing it correctly, then just ignore please.

You need to connect the ammeter or DMM in series with the

yellow wire

and keep it there for the duration of the test.

Then switch the Head Unit on.

Note the current drawn when the head unit is working, should be a few Amps.

Switch the HU off (ACC off and key out, no voltage on Red wire) and note the current drawn on Yellow. It should be lower than the previous test, maybe about 1 Amp or so.

Do not interrupt the power feed in any way! ( You can short out the leads before changing the scale from say 10A to mA and then remove the short once on the new scale, while always keeping the yellow wire connected to the DMM and HU

Changing any scales on the DMM WILL interrupt the test.

Watch the current drain for a few minutes and until the HU does to sleep.

The current should have dropped to 10mA ( it will not go to sleep if the HU still sees +12V on the ACC line)

If this does not work your firmware may not have sleep mode and you can read more/everything about that on the Russian forum.

Thanks viktorsaari, for actual measured currents:

Current draw with MCU 2.8 and 3.1 Sleep mode instant wake up

While operating: 550~610 mA

Acc off: 0-30 sec: 350~450 mA

30-50 sec: 250 mA

After 50 sec: 10.7 mA
[Android Head-Units] fani:
Wow, 2 Amp while ON and 500 mA while off is Way too much. there must be something wrong, in device or in testing.

Here is my measurements with the May 2019 firmware and 3.1 MCU (Link)
[Android Head-Units] biker_955:
I know how to read/use a multi-meter, was an electronic engineer for 20 years.

The 2A was measured at the battery when I refitted it after charging it. The 580mA was measured directly on the +ve wire of the radio with the ignition off and key removed, it was fluctuating from 520-580mA

The power is set to User in the factory settings (per instructions in this thread earlier) but I didn't change it so that was the default.

Hi - I wonder whether or not you are able to modify the radio app for the 9218 - this is the one that has the buttons for PTY/TA etc. I would like this but also to be able to display the radio station name and text like your version does. Is this something you are able to do? Many thanks

I am pretty sure some of these units are not upgradeable. I have a YT9216C and tried the USB method and flash tool. Tried different USBs, different firmware. System doesn't pick-up the files.
[Android Head-Units] Blefish:
If you have YT9216 it only supports flash tool mode, and in that case make sure drivers are working and you have clicked Download before resetting the head unit. If you don't do that, the head unit briefly enters download mode, sees that nothing it communicating and then disconnects. I found this when I was trying to use SP flash tool on Linux.

On a side note, I installed YT9213 December firmware on my device. It brought an annoying glitch where when you set volume from 17-18, it mutes. But I already found a way around it and created an Xposed module, along with my own fix which lets me use the "FM" key on my head unit to start the current media app.

I also uninstalled all Google apps and installed Xposed signature spoofing patch with microG. This allows you to use Play Store, but it is a lot lighter on resources. I can use Waze and switch between Youtube Vanced or Spotify with good performance now.

- replace the camera that they told me it sucks

- install root ( is there a version of TWRP and Magisk compatible ?)

[Android Head-Units] rockrider81:
To understand if the PC cable was OK, I did this procedure.

To check the PC connection, try connecting the device with the MTK droid Tools software.

If the cable connects regularly, the device specifications should appear on the top left window, therefore the connection should also work with FlashTools.

It may also be that the software accepts some other command such as temporary root, backup etc. but I can't guarantee it since MTK DroidTolls was only created for some versions of Mediatek CPUs.

[Android Head-Units] rockrider81:
Oppsss ... obviously now you are afraid of doing damage :D

I have had several experiences on Mediatek devices and SP FlashTools is a bit dangerous.

Before clicking a command you have to check the menu 4 times !!! :cool:

For this reason I first connect MTK Droid and do some tests.

However, I can confirm that with this program you do not damage the device but at least understand if you are connected.

I got one of these this week and installed it today.... Just a few questions existing users might have some ideas about...

1) I can't see any front/rear "fade", left/right balance or EQ of any sort (not even a 3 band high/mid/low). Is this a hardware limitation or am I missing a setting/app somewhere?

2) For steering wheel controls, for analog resistor arrays, they go key1 to ground, right? I derped, saw 2 wires on the car side, hooked them to key1 and key2 without testing anything. Old stereo has one pin tied to ground, so I just need to rip the dash apart again and move key2 to a ground, right?

2a) In the steering wheel control mapping settings, there's a 1K/10K/20K setting down the bottom. Is that the max resistor values? Is it a matter of trying 1K and then going up if some buttons don't work?

A liitle hint

Hello

A little hint.

When I switch off my device, it takes about 1 minute until the left side control panel also goes dark. During this time the cable coming from the ignition is obviously still supplied with voltage. This voltage (via radio) on the cable to the ignition can lead to malfunctions in the vehicle.

Remedy: Solder a diode into the cable with the switched ignition plus (ACC).

Unfortunately nothing is safe ... except death ..... :angel:

On Mediatek CPU terminals I use this method:

- I connect the terminal on the PC and with MTK Droid Tools I check if the connection also works because it involves using a USB male cable in both connectors and I often found cables that didn't work.

- then with my PC and SP Flash Tools I ONLY replace the original recovery with a TWRP recovery (and in any case it is good to study a little how SPFlashTools works)

- I restart the terminal with the new TWRP recovery, I immediately create a backup of all the content and only afterwards through its menu load the file to get the root, load only and exclusively MAGISK and its tool.
