[Q] Help rooting Pumpkin Quad-core Android 4.4 Kitkat Car Stereo

I just bought an Android head unit from Pumpkin Audio http://www.autopumpkin.com/new-products/pumpkin-quad-core-android-4-4-kitkat-car-stereo-double-din-6-2-inch-in-dash-gps-navigation-system-support-3g-wifi-odb2-dvr-air-play-7-color-button-indicator.html
Everything's working fine for the most part but I want to root it to fix a few minor inconveniences. Pretty much the same issues most people have around here(connect to my OBD2 bluetooth device, map steering wheel buttons for 3rd party applications, etc) but I can't find any information on how to root it or even any ROMs for this head unit or it's CPU.
Does anybody know If/how I can root this or even install a new ROM (I don't mind either one)?
Thinks in advance.

You can install any of the pre-rooted ROMs that match up to your CPU(RK3188) and screen resolution(800x480).

Thanks for your reply. I had seen that thread before but didn't see any ROMs for RK3188. There are some in the repos mentioned there but the rooted ones are either for RK3066 or just don't say which CPU they're for. The closest I've found is on the list of Boo's ROMs on the Custom section of the Google Drive repo which says it's KK4.4.4 and rooted but it doesn't say if it's for RK3066 or RK3188. Am I missing something?
Also, I don't know yet if my unit is KGL, Klyde, RoadMaster, GS, JY or MD yet. For what I gather from your post, I can install any ROM as long as it's for the right CPU so, Assuming Boo's ROMs are for RK3188, I don't need to bother checking which kind of unit I have, am I right?

Make sure you match up your CPU(RK3188) and screen resolution(800x480) and you will be fine!

Same for me with the GF. I'll try Malaysk's ROM tomorrow and see how it goes.

the KD-C0410 model uses a DUAL CORE Processor RK3066, you can't use RK3188 ROM's, the RK3188 is a QUAD CORE processor.
in this thread you can find all the development for the RK3066 http://forum.xda-developers.com/showthread.php?t=2660662
also remember that most of Pumpkin stereos are made by KLYDE, so you will not find the name Pumpkin look by KLD

That's exactly what I ended up doing. Malaysk's ROM has been working fine so far since I flashed it on saturday and I was able to change/fix everything I needed.

thanks!

Do any of you know if the ram can be upgraded in these Chinese head units? I know inside the Joying head unit there is what looks like a ddr3 ram slow. I am unsure if the Pumpkin variant has one as well.
If it does, in theory it should be able to be upgraded.
I asked the Pumpkin Auto people if this was possible and they said no. I am thinking they may have said this cause the want the buyer to buy the ram from them instead of using a 3rd party stick of ram.
Anyone care to weigh in on this?

please delete, sorry

Buying a Chinese Android head unit

Hello guys!
So, I have a 2005 Audi A4 B7 and I'm thinking about buying an android head unit for my car. So far I have found 2 head units that look somewhat like the factory one, or that I like. They both have Android 8.0 / 8.1, Quad-Core with 2GB of RAM. Now, are these chinese head units generally worth it? I'm really concerned about sound quality (I have an aftermarket amplifier and subwoofer installed). Now I have a Kenwood head unit and the sound output is decent, can't really complain (better than factory radio).
And I have a few questions.
One of the units is made by Mekede (the factory look-alike) and the other one is made by Wondefoo. Has anyone had any previous experience with these 2 makers?
Also, I do not see an AUX IN on these chinese head units. Do the have one? Is it possible to have one? I'd much rather play music over BT, but is generally the connection stable?
Seeing as they are Android, am I able to install 3rd party apps, such as Vanced YouTube ? Or Waze (or any other app that does not come preinstalled) ?
Generally speaking, how is the boot up time on these units?
They both cost around $210. Are they too cheap? Should I try and save up more? Look for other makers? Most of the times I'm going to be listening to music (either via USB, BT - or any way it can be connected to my phone; or YT) while, sometimes, using Google Maps / Waze. Are these cheap android head units generally laggy when multi-tasking? Does it really matter which one I buy, as they're all "cheap chinese products"?
Here are the links to the units:
1. Mekede
2.Wondefoo
Or if you guys could recommend me another one which really is worth the money, it'd be appreciated. I'd like it to have volume knobs, and the factory look-alike is a plus.
I am sorry if these questios have been asked before!
Thank you!

One thing to keep in mind - RAM amount. 1GB of RAM is not enough for these units. I'd recommend 4GB of RAM, but make sure you get at least 2GB of RAM for sure (and even that may not be enough).
Try to find a unit with PX5 (octa-core) or PX6 processor and 4GB of RAM, if possible. Android 8.0 or 8.1.
In terms of sound quality, I too was concerned. I ended up rooting and installing Viper4Android and the sound quality is great. I'm using an extenral amp, but the internal amp sounded good with V4A as well. Viper4Android gives you a LOT of flexibility in customizing the sound to your liking.

Must be a PX5 or PX6 ? Most of the sellers don't list their processor model, just listing it as "octa-core". I'm aware that V4A can give you a lot of flexibility in sound customization (I've used it on my phone for a while)
Do these head units integrate well with the CAN ?

Here are the more technical names (may help identify them):
PX3: Cortex A9 (Quad-core) - 32-bit ARMv7 architecture.
PX5: Cortex A53*(Octacore) - 64-bit*ARMv8 architecture.
PX6: Cortex A72 (I'm not sure of the details - brand new platform)
From what I've seen, most Android 8.0 units are PX5 and most Android 8.1 units are PX6 (brand new). Units with older versions of Android are probably PX3, I'm assuming. Most of these units do not get "official" major Android version updates - the manufactureres just release new models instead of upgrading existing models (but some can be upgraded via custom ROM's).
Personally, I would probably look for a PX5 MTCE octa-core unit with 4GB of RAM. I wouldn't consider anything older than a PX5/Android 8.0 unit - and like I said, I'd recommend 4GB of RAM if you can find it. The PX6 units are brand new - there are no custom ROM's or anything for them yet or anything. They also seem to come with less RAM and storage from what I've seen?!?!
Only way to be 100% sure what you are getting is to ask the seller - they should be able to tell you the processor type and "MCU" type (MTCE-XXX),where XXX is the MCU type. The MCU is like the "go between" between the Andorid OS and the radio hardware (MCU type can be seen under the Android settings menu) - you may even ask them to send a screenshot of the hardware info from the Android settings to confirm what it actually is.
Just a "general" overview of some of the basics - I hope that helps.
Oh - and if you have a CANBUS car, you need a CANBUS adapter. If the seller is selling a unit specifically for your car, they usually include the CANBUS adapter. That will allow your steering wheel controls to keep working and other items.

Yes. That actually helped. These with 4 GB RAM and at least a PX5 cost more, about $350 so I'm going to wait, save up a bit more, because I also need to convert my car from 1 DIN to 2DIN and that will cost me at least an extra $70.
I also want one that looks like the factory equipped one, so, yeah, I'll just wait another month or so.
Thank you for your answers, guys!

I have a mekede unit supposed to be android 8.1..... It's not it's actually 6.0
This was from mekede official store on aliexpress
They are now not answering my messages and unfortunately I didn't figure this out until after the buyer protection time limit had ended.

Just to post an update to my original post... At first, I thought that the sound quality was great. But the more and more I used the head-unit, I found that sound quality was NOT up to par with my previous WinCE head-units. And I also ran into noise-related issues. I did everything in my power to try and resolve these issues (including using external amps for better sound quality), but in the end, I gave up and re-installed my WinCE head-unit.
Unfortunately, from my experience, these Android head-units just aren't up to par in terms of sound-quality and noise-rejection. I had noise-related issues from the LED backlighting, USB devices, wifi and bluetooth wasn't very good either. Hopefully, they continue to improve upon these units, because having the head-unit run a full version of Android is great - but sound quality is also important - and even more important to some (like me). Would be great if the big audio companies starting building full Android head-units (Pioneer, Kenwood, Alpine, JVC, etc).
Since my WinCE unit supports Easy Connect, I can still get the advantages of Andoid for certain things while also having fantastic sound-quality and no noise issues. Best of both worlds. Granted, the WinCE unit is significantly more expensive ($699 vs $350), but just like anything else - in most cases, "you get what you pay for". The WinCE unit that I'm talking about specifically is the Dynavin N7 - and they use high-qaulity sound components. But I also had Rosen WinCE head-units and they sounded great as well (but again, significantly more expensive).
All depends on what is most important to you - software flexibility or sound quality.

My new 2021 PX6 from Phoenix Automotive Vertical Fast Boot OEM fiber option. Had this for about 2 months. I use it with an external OEM AMP. Used in a Lexus.
AMP is not fiber. The unit is a PX6 MCU RL78c (2014 Chip-set) NCHHWY V332-0 , Framework px6-userdebug 9 PQ2A 190305.002. OS 9.
Audio is very good! I love the sound. Speakers: OEM Mark Levnson in the front, 6.5inch JBL GX600C + Sound Ordnance M2-10DVC 10inch in the back.
Tested only with stock HU.
What works on the stock PX6:
(With correct wiring harness)
1. Fast-Boot. After first 2 setup boot-ups, on is instant for 24 hours of nonusage.
2. AC controls work (Cooling).
3. Searing Wheel controls work out of the box on Lexus w/canbus included.
4. Audio player works but not a good GUI.
5. Phone works with Bluetooth.
6. Android Auto is installed and works.
7. DSP Sound works with an EQ and many settings, GUI is good.
8. Most User Settings seem to work. Wheel mapping may stop after Fast-Boot for 5 minutes (bug).
9. Navigation (Google Maps) works, GPS works.
9.5. Maps works Off-Line in Google Maps.
10. Radio with about 16 memory storage.
What is not working in a Lexus / Toyota :
1. Factory Settings. All-access is denied. Locked out! Big Issue for me.
2. GAS monitor/usage. This should work out of the box. Phoenix says it is not working and is disabled in Lexus. BUT is advertised to work on the Phoenix site.
3. Sound MAX loud setting will NOT save after reboots. After boot, the sound is all the way up, loud. After talking with Phoenix tech, no fix. However, if FastBoot is on, the audio may save to a lower setting for about 24hours. If you don't use HU for 24 hours settings are lost again..
4. Screen will reflect windshield in GS Gen3 Lexus. May be an issue in sunlight.
5. If you wear Sunglasses or have glasses that do auto shade to dark, you may not like the screen because it can be hard to see.
6. Radio- Local / Distance not working. Can't find a fix. However Local radio is working fine. I get most local stations clear.
7. Temp display worked for 2 days now showing -40 at all times. (No fix).
8. Fast-Boot image changing. The stock app that changes the BOOT-Image will not work. It is out of date and will not work with Android 9+. It needs an update from Manufacture. A Phoenix Auto add-on app (download), also will not work, out of date. App complains of an Error with the Android version.
Add-On that work:
1. Musicolet from Play Store. The Stock Audio player sucks big time.
2. Bluedriver OBD2 reader.
3. Torque Lite or Pro OBD2 reader.
4. Function Generator, from Play Store.
That's about it.

Guidance for Android Head Unit

I currently have a Kenwood KVT614 head unit that I hate with a passion. I can't stand the useless screen (without apps it really serves no purpose), the navigation software and about everything.
As a result I am considering switching the head unit out and I love the idea of something running android.
My car is an electric car and it only has a single DIN slot, so I am somewhat constrained in my choices.
Ideally I am looking for an android head unit that covers the following:
- Can run android apps, e.g. navigation (both offline and online via the phone)
- Tethering - I read that some headunits have issues with Bluetooth tethering which is obviously much better for phone battery
- Having an electric car, I actually want the headunit to turn OFF (not sleep) when the car is off
- Screen size: not too big - probably 6-7 inches or I saw some "very wide" widescreens at 8.8 inches that would fit well
- I also like the idea of screen mirroring or android auto (and carplay) working but I would very much prefer for this to work via wireless (not some stupid cable)
- power consumption would ideally be as little as possible with this being in an electric car ...
Does anyone have any recommendations?
I have been looking at some of Joying units, since they seem to be the most modern android head units with 4GB RAM, 32 or 64GB storage and running Android 8.0 or 8.1 …
Would love to get some feedback.

And how do I determine whether a head unit is a MTCB or MTCD, or whatever?
Is there a database or list somewhere? Does this no longer apply to new headunits?

It's too bad there is no sticky or wiki with recommendations and some guides.
Once you know your board (MTCx) there is some decent info, but for someone looking for a single DIN headunit there current forum setup is pretty useless.

No one helps here much.

The new joying intel based units have a new dsp chip that will blow everything out of the water in android platforms. I ordered on last week. Will be doing a review on it by next weekend hopefully

Newbie Help! Pumpkin or Dasaita Confused

Hello Members,
I'm looking to convert my Volkswagen Stock Stereo Unit (RCD 310) to an Android HU, My Stock RCD 310 served me well without any trouble for the last 7 years, but it was a very basic stereo without any fancy techs involved in it just a CD /USB player. Hence my hunt for an upgrade began initial plan is to upgrade it to RCD 340 Series to keep the stock look and with updated features like Android Auto, Car play etc. But since they are mobile phone dependent which needs to be constantly connected to your mobile phone to access the android auto features i ruled out that upgrade and decided to try independent Android HU, After a Lot of Online search I narrowed down to 3 different Android Head units in Ali express.
1.) Pumpkin Model Name:ND0380B (Pumpkin Android 8.1 Car Multimedia Player 2 din 9" Car Radio GPS Fastboot Car Stereo No DVD Player For VW/Skoda/Golf/Volkswagen)
I liked the look of the above Model but its a Quad core processor with 2GB ram and also after having a conversation with a person who own it he was strongly against this player and its running slow and have few lags. Hence ruled out
2.) Pumpkin Model Name: AE0373B(Pumpkin 2 Din 8'' Android 8.0 Car DVD Player GPS 4G RAM Car Stereo For Volkswagen/Skoda/Golf/Polo FM Rds Radio DAB+ Headunit)
I have almost finalized the above head unit and right before placing order I bumped up into Dasaita Brand and looked into their models. Luckily I found a similar Pumpkin 9" model in Dasaita which had PX5 octacore with 4GB ram (assuming this will run faster. ) Dasaita 9" Android 8.0 Car GPS Radio Player for Seat Leon Alhambra Altea Toledo with Octa Core 4GB+32GB Auto Stereo Multimedia.
Now I'm confused which one to choose, After reading some couple of XDA threads i understood all these chinese models are similar but would like to know which one is more reliable and have a better customer support Pumpkin or Dasaita, Would love to hear from some owners who own any of these devices in this forum.
TIA
Mods: If this thread is posted in wrong section, Please forgive and move to the correct section.

Android Auto - use without a phone

Hi there. I have recently installed an aftermarket Android 11 screen in my car. I set up the unit with a 4G SIM card so it has its own isolated internet connection, as I want this entire unit to be self-sufficient and never have the need to connect a smartphone to it.
Is there a way to run Android Auto on this Android unit as a stand-alone app without having to connect a phone or external device to it?
(this seems like it should be a basic and common question, but I could not find an answer using Search)
TIA.

No one knows what the head unit is, out of the many unit types and manufacturers.
What have you identified as a possibility to solve your problem from reading the forum

There is not really a "brand" per-se, it's a somewhat generic aftermarket Android unit manufactured in China and distributed by DMP Car Design for a Mercedes W205 chassis. The device is "unlocked" and I can install almost anything.
As a network device, It identifies itself as: 'Bengal for arm64'
Specs:
12.3" Screen | Android 11 | 6GB LPDDR4 Ram | 128GB Storage | Qualcomm SnapDragon 662 (sm6115) 8-core kyro 260 64-bit CPU
I would think most of this has no bearing on the app having the ability to run stand-alone (except for the Android version).
Thanks!

For what reason you want to mess around with Android Auto?
This app is meant to connect a phone with an OEM head unit to mirror the screen of your phone to your head unit.
In fact:
Your new head unit is able to handle all the apps itself a lot better as any AA installation would do.
If you don´t have a phone connected, you won´t be able to make phone calls at least.
So I am really curious what you expect to get and the reason for your question.

Hi, did you resolve the problem with your android head unit because I've got the same predicament . Thanks

Since I have work accounts on my phone, I cannot connect to external devices. Additionally, I prefer not to have my car's system or devices be dependent upon an external device to function. From my perspective, the only requirement I should have to make everything in my car work is to have a key, that's it.
I like the clean UI of Android Auto and it works well for native Google navigation and music control in one simple interface which is why I was looking for an "easy" way to run Android Auto on my aftermarket Android car screen without having the dependency of a connection to a smartphone to function.

Hi there. I did not spend a lot of time pursuing this as I ended up going down too many rabbit holes in search of a solution.
I dropped trying to run Android Auto as a stand-alone app without a smartphone connection and went with FCC Car Launcher. In the end, I gained a huge amount of functionality and customization by using FCC. I now have a Google moving map, music controls, and much more on a single home screen without any dependency on a smartphone. (my headunit has its own 4G internet connection)

Using Fcc is surely the best solution.
As I said... Stand-alone Android Auto is not possible. you always need a Connection between phone and head unit. This is the way this app works...
I already use Fcc nearly since the start of development and I would not use anything else.

I have a 2016 RAV4 with Entune radio. Looking for a GPS Navigation capable unit. I have an Android phone. Seems like an Android OS wireless and wired head unit would work. Extensive research led me through Pioneer, Kenwood, Alpine, Sony: all poor values. Car stereo dealers want a fortune to install. I value function and reliability. Any suggestions on a plug-and-play easy install unit that will keep my steering controls and factory backup camera? T'eyes CC3 and Dasaita Max 10 both are on my short list. Prefer to buy from US only.
