hello, I read about several people who have problems with eunavi px6 dsp (I think it's a remarked bosion model).

I also have the same problems.

using the rca outputs connected to the amplifier and active subwoofer the dsp options do not work, only the equalizer part works.

After many days of messages with eunavi today they sent me a new firmware and mcu update, but even this does not work.

Have you solved the problem with dsp?

Some settings in there are very useful actually.

Upgrades

After my adventure of fixing a totally bricked STM32 unit, I had it working but with some serious issues.

- The unit will overheat and sometimes reboot.

- Sometimes apps will close unexpectedly and trying to reopen them again would fail.

- Sometimes it first freeze, then remain black for a while and after some time it would reboot again.

- Sound was rather poor.

I thought it was time for an upgrade so I did the following:

1. Found an old heat sink from a retired PC's CPU and cut it in a proper dimension

2. Fixed the heat sink with thermal paste and some hot glue

3. Changed stock 3.300 μf 25V capacitor with an Mundorf audiophile 15.000 μf 25V capacitor

Result:

- Temperatures went down around 20 C from 65C-75C to 45C-55C and occasionally 60C (the temperature in Greece now is around 30C)

- Never experienced any freeze or reboot. Unit works much more reliably.

- Audio was improved especially on loud levels with a deeper low end. I have Focal loudspeakers not easy to drive

Next step is to install Malaysk custom firmware. Hope it works just like my other MTCE units

Fully working at 100%

Original supplier Erisin sent me an OS update named os_update_HC1E0202-P0N-1.1.4.3.1_20191130_122815. Apparently firmware KC1E0113-PA1 that I used before, was not fully compatible with my unit and caused a series of issues like rear camera not working etc. Now with the new firmware everything works as it should. Rear camera ok and the unit feels really snappy! Along the way I have also done a little tweaking and I have a perfectly working unit!!

Malaysk has already made a custom rom for STM32 platform units, but in a couple of weeks will release a fully compatible ROM. Can't wait for the transition!!!

But after rebooting root access is lost. (even when it says Es File Explorer is granted root access)

I couldnt copy new boot animation file. And when i try to rename system file, ES File Explorer says "rename success" but the name didnt change.

How do I reroot again? Thanks!!
[Android Head-Units] kingdew11:
Thats the Loudness in EQ. Just enable it.

If you have to enable it every time you boot, it probably means your HU is not getting a permanent 12V from the battery when your key is off.

Like checking if the ACC and Permanent 12V is swapped at your ISO power socket

Hi have you solved this problem? How do you remount/reroot. I dont mind rooting it again whenever i need access but could you teach me how to remount please?

I cleared devices on adb,

Then adb connect to current IP

Then adb remount.

ACCESS TO SETTINGS NOT LISTED

I have a Threecar 4G/32G no DSP Android 9 head unit. I was having trouble with my Sygic sat nav program losing GPS fix if I opened up another program (eg Radio or Media). When I went back to Sygic it would sit there showing "getting position" but never locked on again. Someone suggested it was because Battery Optimisation was turned on for the Sygic program. Problem is there is no setting for Battery in the head unit's list of Settings. I installed QuickShortcutMaker from the Play store. When you run this it gives a list of Activities. Scroll down this list and click on "Settings Suggestions". Another entry also labelled "Setting Suggestions" comes up below it. Click on this and an Icon and a fair bit of info appears on the right side of the screen. Click on "Try" and a new screen appears which is a search screen within Settings. In my case I searched for 'battery" and "Battery Optimisation" was listed where I was able to turn off battery optimisation for Sygic. There is an option at the bottom to create a shortcut but this did not work for me.

With this app you should be able to access all the standard Android Settings missing from the head unit's Settings list.

How I can do it?
[Android Head-Units] Robbo69:
There are two cables labelled Key1 and Key2 coming from the main connector on the back of the unit. One of these has to be connected to the Steering Wheel Control cable in the car's wiring harness. Usually Key1 will work but in some cases (like this unit) Key2 works better. On your unit, see where the Key1 cable is connected to the car's wiring then disconnect it and attach the Key2 cable there instead. Leave the Key1 cable disconnected. You will then need to go into the Steering Wheel Controls app on the unit, reset the settings then re-assign the buttons.

I had the same problem. Turned out i had my ACC (key on - power on) and permanent 12V wires swapped.

That means when I turned off the car the HU shuts down immediately and without any power supply to sorta 'maintain its memory'

Swapped the pins and they work fine now.

If u had the same problem as mine, you should have these problems as well:

Can you provide details for the swc fix? In ford mondeo mk4 the only problem is with the left right buttons which do some random actions usong the radio or musoc player. Only Up/down vole works fine.
[Android Head-Units] OperatorB:
Hi there!

I do not know how Mondeo mk4 was designed but these are my initial thoughts:

-firstly I would redo the training process with the problematic buttons

-if still not good then I would check the resistance for the problematic buttons to verify that the behaviour is due to small difference in resistance in case of those buttons. To measure you need to connect your multi-meter to the two wires comig from the swc module then measure resistance while you press down each swc buttons one at a time. Imagine the swc module like this:

http://www.martyncurrey.com/wp-content/uploads/2014/12/DIY-Single-Wire-Keypad-01.jpg
[Android Head-Units] Moufa:
Tried to solve the problem with the SWC by contacting the seller.

The facts are: buttons should work properly through canbus decoder, but they work in some way, by choosing the correct protocol through factory settings but not perfectly. The converse+ screen works (is for ford mondeo mk4 2008), Up/Down volume works, A/C display works, but right/left is messed and you cannot train the buttons through SWC app (does not recognize the pressing states). What I found is that connecting the Key 2 cable from ISO harness to the unit cable connector (it has already sockets to connect them) and disabling the canbus protocol, it lets you train the buttons through the SWC app but converse+ does not work.

I guess the canbus protocol or the MCU firmware may have a kind of fault/bug with the specific car model.

If there is anyone with specific knowledge maybe he could help and solve the issue.

A last thing, has anyone tried to disable the alternation of the reverse camera, I don't use the camera and it is annoying when choosing the reverse gear, to switch to blank screen.
