Oh, I thought your unit has android 9, I reviewed the thread and you have updating firmware difficulties. As I understand your device is not operable for now. Please try the instruction/archive from this post. It is needed to flash recovery and system partitions using PC (they both are in the archive). After that the update from USB Stick should work.

Radio.apk

Can someone please extract the radio.apk of the newest Kanor Firmware or tell me how to do that. I would like to test it on my Pumpkin ND0294, because the original radio app doesn´t work very good on the pumpkin. AF is very slow and reception is not so good.

I have read at the 4pda.ru forum, that the sound is depending on the mcu, so you can change firmware to newer or older but sound stays as it was, if you don´t change mcu. That´s right?

I am frightend to lose the good sound my pumpkin has at the Moment with installing new Firmware.I had a xtrons unit with the same Radio chip and IC but sound was terrible, meanwhile Radio reception was extraordinary good. I have read with Google translate ;)at this Forum that a user had a bad expirience with Sound / Radio Signal reception after installing new mcu and Firmware.

Thanks
[Android Head-Units] _yuzo_:
Yes, just not update the MCU. BTW what is the version of your current firmware/MCU?

There is no separate Radio.apk, everything is combined in CarUI.apk in our case.
[Android Head-Units] Strike03:
Ah, ok..i didn´t knew. On my old Pumpkin 4.1 Head Unit with Malaysk Rom it was no problem to install another Radio.apk. For example the Flat Radio Mod. Just replacing the old with root browser. Sad to hear this doesn´t work for this one :(

The current firmware and MCU are:

201905071721 + MCU CSN2_04162019_112307

Can i go back to this my firmware, if i install the newest of Kanor to see if Radio works better?
[Android Head-Units] _yuzo_:
Kanor is just a seller, as well as others. All units with CSN2 are made by Klyde.

Your current firmware is present in the initial message of this thread. So you can always download that (May 5th firmware + April MCU) and downgrade, but the most recent it better and I'm sure you will use it :)
[Android Head-Units] hugoboy:
Thank you for the how-to. I actually figured it out by pressing all of the buttons :confused: to see what each did until it rooted. After I rooted, I was able to installed TopNTP which seem to fixed my GPS lock issue, but only for a day. Curious, I couldn't find the gps.conf file. I guess I will have to remove my unit and check on the GPS antenna.
[Android Head-Units] Clandaries:
And if you turn on your smartphones hotspot, your head unit can use the phones data to.

I also never understood why use AA on a Android head unit.

Regards
[Android Head-Units] rigattoni:
In this case I would not even think about using an Android head unit, or switch the provider of your mobile, if tethering is not allowed.
[Android Head-Units] skorpio682:
Regards! Sorry if your English is not perfect! I use Google Translate for help! I would like your help regarding a "problem"! I bought a car head unit Hyundai i40. I tried to find out the manufacturer based on the MCU and software on the device! I received the information on an internet site that you could help me solve the problem! The GPS part of the device is not working properly! I tried several navigation applications and tested the GPS antenna several times. The problem is that while driving, the real position of the car and the position on the map differ by about 200 meters! Car moves further than what you see on the map! If the car stops at a traffic light, the position catches up with itself! The difference is more noticeable at higher speeds! In a city where there are many streets, the device is almost unusable! With the GPS testing application, I noticed a possibility of an error, which could possibly cause the problem! The program indicates that the GPS time is very bad! It shows 1970! I would like your help in this! If there was a new software or MCU update, which would make the gps application work well, that would be great! Or how could the clock of the gps module be set to the exact time? I took pictures showing the software version and the MCU, as well as the GPS error! Thank you if you can help!
[Android Head-Units] rigattoni:
To narrow that down, install GPS Aid from GooglePlay and try to fix your GPS.

...and make sure you set the correct time zone.

What´s about your GPS antenna, where is it mounted? --> Picture
[Android Head-Units] skorpio682:
The gps antenna is definitely in the right place and works well! I am sure of this because the previous head unit, which was a px3 mtcd device in the car, worked without any problems with the gps part.I tried the new head unit with that antenna too! The situation didn't get any better!At least it's no better than the gps testing apps I've tried.I downloaded the gps aid application you recommended from the play store. Actually, I didn't even understand why you suggested this? Apart from being full of advertising, it can't be used for anything!The time zone is also set correctly! I don't know if it is possible to set the GPS module of the device and where to set its clock?It would be a great help for me if you could recommend a software update for the device!I tried to find out the parameters of the device on the Klyde manufacturer's website to see if that would help solve the problem!
[Android Head-Units] rigattoni:
Well... Do yourself a favor and get in contact with the seller for updates.

I don´t know what is going on on your unit and how you set it up, setting time zone and whatever.

You are not able to set the time of the GPS, because it is provided by the GPS data and corrected with your current time zone, which is set in the Android settings.
[Android Head-Units] megatronhalo:
Hello everyone, I have a px5 model with Android 9 and want update to the newest version. Just wanna be extra sure iam installing the right thing, would love the help
[Android Head-Units] rigattoni:
This is written on the first page of this thread.

Look for the latest MCU without DSP and then the latest firmware for PX5 in there.

The How-To is also there.

Keep in mind, that each upgrade can get wrong. Don´t blame anyone if the unit is afterwards not usable afterwards. If there is no real reason to upgrade, keep on Android 9 and just use the latest Android 9 version from the first page.

I have a problem with a car radio that takes time to turn on every time it has to be reset

*For Hyundai i30 2017 2018 Android Car Radio 2Din Stereo Receiver Autoradio Multimedia Player GPS Navi Head Unit Screen*

Can it be updated? A seller on a aliexpress *

Vehicle Parts Professional Store*

* does not want to give me an update and does not solve a problem. More than 6 months have passed
[Android Head-Units] rigattoni:
Which exact unit is that and what is the firmware and Android version on this unit?

Please switch the unit to English and add complete screenshots of the "About tablet"
[Android Head-Units] teggare:
Sorry, thank you very much
[Android Head-Units] rigattoni:
Okay, no problem. Now we can see what your unit is about.

First of all, your unit has most probably the newest firmware and MCU installed. So there will be no update available... at least not now.

Regarding your first posting:

If the unit is correctly installed with the needed CAN box, the unit would start up within less than 3 seconds.

So following questions:

Did you buy also the right CAN box to get connected to the OEM plugs?

At least did you buy a CAN box with the unit?

Did you set the right CAN settings in the settings menu?

Who did install this unit?

Background:

Newer cars are fully connected with the car. Means the communicate via CAN bus and the head unit gets the ignition signal via the CAN. It also secures, that the unit goes into a deep sleep mode, because only the clamp 15 will be unconnected electronically and the unit keeps the connection to the radio fuse which has constant power. The power consumption during deep sleep is around 7 to 13 mAmps which does not damage the battery even if the car is parked for weeks.
[Android Head-Units] teggare:
i don t think it has been installed before cuz i didn t get it...

the one who installed the radio sells car accessories ....

please could you give me the picture of this canbox ,and what s kind is suitable for me?
[Android Head-Units] rigattoni:
Sorry to say, but the one who installed the unit should be able to answer the question if he installed one, as this is a seperated small box with connectors to the OEM connectors and to the new head unit. If there is no CAN box installed in the back of the radio, you should get in contact with the seller and get one from them for your car.
[Android Head-Units] teggare:
I went to a repair shop today and they told me that my device is not supported CAN box*

He told me that the only solution is to provide him with a power source directly.

Currently it works directly from a battery power source, everything is fine

Thank you for directing me
[Android Head-Units] rigattoni:
Well... I fear the repair shop is wrong.

The CAN box is connected between the OEM cable tree (using the OEM connectors) and the head unit.

Example for Hyundai I30:

This box provides ignition, batter pos, ground, backup camera, handbrake signal, Speed...

All other functionalities are dependent to the OEM radio which was in there before.

This CAN box secures, that your unit goes in deep sleep mode, if you turn ignition off and turns on, if ignition is on....

If this is also now the case, okay, but you don´t get reverse signal and whatever was working before.

If you switch the ignition on now... does the unit come up within 2-3 seconds? If not, the installation is wrong.
[Android Head-Units] teggare:
Yes when i click on radio starting button it works in less than 1 second without logo because we switch it directly with electricity

The attached CAN box picture you sent is not available in my country i don t know where i can buy it

*before*

It has a deep running starting problem, when i switvh off the key of my car the electricity goes down

I think this is the right solution, to let it always be on and turn it off from stand-by

What do you suggest? What do you think about it? Is it a right solution, because if i cut electricity it will take a long time to be restarted

...camera reverse car ...work camera and all accessories are working on the radio , and nothing is changed everything is working as before
[Android Head-Units] rigattoni:
If you press the On-Button on your head unit and it is directly on, then it is installed in the wrong way.

It will drain your battery, because it never reaches deep sleep. Just now just the screen and amplifier is switched off, that´s it.

Sorry to say, but you really should search for someone who is able to connect the unit as expected.

I don´t know anything about your technical experience and may have some sort of measure equipment.

If yes:

If you pull out the radio and have a look at the cables coming from the head unit.

There you can find a yellow one and a red one.

On both you should see a label.

One should be labeled as BATT and the other with ACC or IGN...

You really need to make sure, that BATT has always +12Volt and the one with ACC/IGN should only have +12V if the ignition is on.

In case you don´t have any CAN box, you need to search for a connector in the dash which only has +12V if the ignition is on.

Check cigarette lighter, AC regulator, Vent... Whatever you find, you can use it, because there is really minor current on it to switch the radio to on. The one marked as BATT, ONLY this one needs constant power.

You may find out, that now the red and the yellow one are connected together to constant power.

That drains your battery!!!

Change that yourself, or search for someone who uses his brain.
[Android Head-Units] teggare:
Yes, but before it was not working. It takes 30 minutes to run to 1 hour

Every time I use a car, it takes 30 minutes to start

In the morning it takes 1 hour for the radio to work !!!

*CAN box *

I think it is just used for me to show some features!

Explain to me how will solve the problem of electricity?

I don't think it will solve the problem

It will remain as before

Incorrect clock delay Radio stations are not saved

I think the problem is with the radio itself, and the power supply is not cut off
[Android Head-Units] paralias7:
Hello again. Do we know if there is an option for px5's to hide volume slider on screen when we increase or decrease volume?
[Android Head-Units] rigattoni:
This is no slider from Android, this comes from the main-board. No chance to get rid of it.
[Android Head-Units] paralias7:
Ok. I didn't knew that. So no way to hide it? Not even with root?
[Android Head-Units] rigattoni:
Not even that...

hi to everyone,

i am new in this forum.

i have a px5 pumpkin radio with android 8, yesterday i have update mcu and firmware with the last android 8 file find here.

i have a strange behaviour... the gps seem not to work with the clock and google maps.

Just for try i have installed the waze and with this program the gps turn on show the icon and works, so the question is:

there is a way to make the gps stay always on? or there is a fix? or have you any suggestion?

thanks in advance
[Android Head-Units] rigattoni:
Switch back to the original MCU and firmware and test again. Just blindly installing any updates is dangerous, even if they have the same prefix in the name.
[Android Head-Units] jaes77:
thank you for your advise now the gps has turn back to work like before... i did the update because i have a problem with the voicedialing in the sense of when i ask to call "a number" or "mamma" google say that is calling but doesn't pop up the bluetooth application, the strange thing is that everything else is working perfectly and if i use directly the app buetooth it work.

any ideas why?

thanks in advance
[Android Head-Units] rigattoni:
Sorry, no idea and I did not ran into this issue in the past with units based on Android 8.

Best to do is asking Pumpkin directly for an update for your unit. As I already wrote... There are too different units on the market which have different base hardware (screen, FM tuner, BT-Stack... you name it...).

Unfortunately the prefix is the same for all units, so it´s quite obvious that it can happen that the already provided firmware versions is one which does not support something.

I would go the way towards Pumpkin.
[Android Head-Units] Azuraii:
I'm looking for some help with a persistent network issue on my unit. The device is able to connect to a wifi network but has no connection. I've tried troubleshooting on my own as much as possible.

- The device says it is connected to the network and does not say 'no connection'.

- I have tested on multiple networks, all with the same result.

- I have tested different bandwidths on different networks, both with the same result.

- The unit receives an IP address from the router without issue.

- The unit is viewable from a modem.

- I have reset the wifi settings.

- I have factory reset the unit.

- I have tested with multiple applications - including Google Maps, Play Store, YouTube, Chrome, Facebook, and more - but all are unable to connect to the internet.

- I have contacted the seller but have received no support.

- @rigattoni's comments on this thread have prompted me to contact Klyde directly to see if they can be of any assistance. Awaiting a response.

This hasn't always been an issue. I was able to connect the unit to a network with internet connectivity when I purchased it. The unit has not been updated or modified in any way since I purchased it. Any help would be greatly appreciated.

Hello! I bought a Klyde px5 head unit about 3 months ago. All were working great until yesterday. While i was driving, the unit shut down and rebooted!! After that i lost all of the radio memory stations and also all the settings i had made to the dsp.

What do you think may be the problem?
[Android Head-Units] marchnz:
Crystal ball doesn't have a clear vision thread hijacker. Sorry.
[Android Head-Units] paralias7:
What do you mean by that?
[Android Head-Units] lew26:
You want a guess? Loose power wire connection. Constant (always on) power isn't properly connected.
[Android Head-Units] paralias7:
The correct cable (yellow one) is connected. I always have constant power. It happened only once in 3 months.
[Android Head-Units] gassnico:
I think that the system has rebooted due to an internal software bug like blue screen on windows ! I already had one time this issue in 4 years !

I already asked few times to klyde to add a way to backup radio configuration in their future development without succes
[Android Head-Units] paralias7:
So it happened to you also? hmm. And you also lost radio memory stations and dsp settings? Let's say that it was a reboot from a bug. But the power cable(yellow) was all the time connected. How did it lost these things i mentioned?

That's what it worries me. :unsure::unsure:
[Android Head-Units] gassnico:
yes I loose all setup ! I think that all is in ram and erased after a full reboot
[Android Head-Units] lew26:
I lose radio presets all the time. It happens rarely if I turn the radio off before turning off the car. It happens frequently if I turn off the car while the radio is playing
[Android Head-Units] paralias7:
Indeed a Klyde fix is very important for this!!
[Android Head-Units] Azuraii:
Any help with this would be greatly appreciated.
[Android Head-Units] paralias7:
I think Klyde will help you on your problem. He helped me when i had a problem with the rotary encoder (volume knob) of my head unit. Did you contacted him via email or facebook messenger?
[Android Head-Units] Azuraii:
I send them an email. Fingers crossed there's some assistance there :)
[Android Head-Units] paralias7:
Try contacting him via messenger. I firsty contacted him via email, but i didn't get a reply so i contacted him via messenger and we started talk about my problem. He took me step by step to understand what problem i had with the volume knob, and eventually he solved it! At the end he sent me an android version with some code i had sent him from my head unit. I installed it and now is working perfectly!!! Of course all of that was with the help of a very helpful person which is @rigattoni

I am looking to update my android version from 10 to 11 or 12 I have px6 mcu csm4. Any help would be greatly appreciated.
[Android Head-Units] rigattoni:
There is currently no upgrade for Android 11 or 12 available.

BTW: It would eben not be easy to upgrade (it is no update) as the complete memory management would be different and also all partitions are different.

If you don´t have any major issues... keep it as is, otherwise get in contact with Klyde and ask for the latest greatest update with Android 10.
[Android Head-Units] HellmetButter:
Hi, I wanted to query whether my device is completely bricked or not, or whether I'll just have to buy another.

I followed post no. 5 'Upgrade to real android 10' after confirming that my unit had a fake android 10 installed. It is a PX5 with a CSN2_D_xxxxx MCU.

- I confirmed it had a usb20_otg usb connector.

- Installed the relevant px5_10.0_burntools, DriverAssistant & AndroidTool.

- Installed the apk and entered MASKROM mode. AndroidTool could see the device in this mode.

- Hit 'run', and installed Android 10. This finished without errors.

The unit rebooted into a black screen and does nothing else. The buttons light up when I turn the headlights on, but I can't enter recovery mode or see any response from the screen whatsoever. The button illumination goes out when I hit/hold the reset button, but then turn on again when released.

As the install appeared to go fine, I'm dubious that the 'disassembly method' is going to do anything, as it's using the same files. I can't find much more information on this thread about recovering from this state, and I suppose these MCUs aren't especially common, as there's no other ongoing threads discussing them.

Anyway... any chance of recovering it here or is it done?

Cheers
[Android Head-Units] rigattoni:
Sorry to say, but did you really read and follw the steps in posting #5?

Please read it again and follow the steps one by one.

...and just to mention: This is nothing to be done in the car.
[Android Head-Units] HellmetButter:
Hey, yep i followed the instructions (I'm not a total newbie at this), and I can't follow the steps again as that'd require a working unit ;)

I'm really just curious at this point if these things can be successfully 'un-bricked' - as information surrounding this specific hardware is fairly scarce.
[Android Head-Units] rigattoni:
You don´t need a working unit if you are able to connect via MASKROM.

That the light of the buttons is still working show, that the unit has just no Android installed.
[Android Head-Units] HellmetButter:
Apologies for the confusion - to clarify, I can no longer connect to the unit in MASKROM mode via the same usb20_otg port that I previously used. The unit is no longer detected at all.
[Android Head-Units] rigattoni:
Ah okay, didn´t get that.

In this case you really need to disassemble the android board and get it done as shown in #5.

There is no other way to get it back to life.
