Neither, they are mostly identical in terms of receive performance. If you take some time, you'll find my post about this.

I think you have confused chips with modules.
All of these "chips" are exceptionally good.
Receive performance is impacted by module manufacturer and software implementation driving them.

ok my mistake...
I said that because i had a xtrons with TDA7786 and i change it for a xtrons with NXP/TEF 6686, the specs and android version+soft was identicals except the radio chipset and the reception/stability and rds work fine on the 6686 model.
Thanks to you

I would read all threads and from that make your decision. This is complicated with a lot of different opinions. Quad core
and 1024 to me is basic. KLD, Joying, Pumpkin are well known. Some of them have BT audio problems, but fixable.

Looks like a good choice, but be careful because it says in the ad at the top SDRAM 2 GB+NAND flash 16Gb opt, optional?

ok so I bought the radio listed at the top, is there a root or rom and a DVR app that will work with the two cameras, any help would be great.
It's not an MTCB device. You should try the non-MTCB Android head unit section for assistance.

HIZPO Offering Quad Core A9 7" w/ Android 7.1

https://www.amazon.com/gp/product/B01JULCTYE/ref=ox_sc_act_title_2?smid=A17YHR60ETNWLC&psc=1
Thoughts? Thinking about ordering one.
I just returned a headunit from ATOTO because it worked like crap.
I like the prospect of 7.1 and offline maps already installed.
Quadcore vs Octacore I don't think makes a huge difference here.
Would love to know opinions.
I have a similar product to this with the product ID "B071LT7LC3" on Amazon. (I cannot post links yet) From the looks of things, my unit is likely the same hardware as yours, only with a different front panel and added DVD player. This is the information I read from the device:
MCU version: MTCD_XRC_V2.52_1
Build number: px3-userdebug 7.1.1 NMF26X eng.hct.20170527.145603 test-keys
Kernerl version: 3.0.101+ [email protected] #550
Model: px3 (800x480 O)
I sadly managed to brick mine by running an incompatible root method for Joying devices via Wireless ADB. I have not found a root method actually works on these units yet. If you are looking for an Android stereo that you can root, look elsewhere. I got a copy of the firmware from Hizpo, but not even that can fix the damage I did to it. It is with this warning I hope to prevent you making the same expensive mistake.
Note that you cannot use these units with a PC via USB, you must use Wireless ADB using an app. Use "126" to get into your factory settings and play with those, or "adbon" to enable debugging. You can also download a Development Options app to reach those settings, as they are hidden. The various methods of recoveries, including the one provided by the seller (Hold down the power button, turn on the power to the radio, release after 5 seconds and wait 30 to reach the recovery), did not seem to work for me either. It is possible I corrupted that too, but I am not sure.
I will happily share any other opinions I have about the unit if I ever manage to get it unbricked.

FYI - there are literally 1000s of different MTCD units by about 10 different manufacturers, they all share pretty much the same hardware and the software is interchangeable

But certainly not root methods and certain firmwares. Pick the wrong one and you can brick your device beyond restoration - to the point where the recovery does not work and no firmware update worked to fix it. I had to get a new unit.

Yes, all RK3188 MTCD units are the same inside, they use the same SoM and ROMs ARE compatible as long as you get the screen res and processor type correct and even if you get the screen res wrong its no big deal, it wont brick.
However if you flash the firmware from an MTCB unit, or from an entirely different, unrelated unit , its sounds like this is what you did.
I was looking at this, but when I noticed it said PX3 I decided to skip.. Doesn't make sense to not have the PX5 chip.
Now if there was a version with a PX5 on the new os Id be interest.

Sure the PX5 will be fast, but the PX3, especially with 2Gb of RAM is perfectly good.

If you decide to order, please update with your impressions. I too tried the ATOTO M4 garbage head unit, and it has almost encouraged me to give up on them entirely. If you find this one to be worthwhile, with it being at a similar price I might give it a shot.

No need for him to post impressions - its an MTCD unit and theres a whole forum about that you can read to see what theyre like :

Installed, and I'm definitely impressed. Very zippy and sounds great.

No, not all units are MTCD, I ve heard a rumour that a company is working on MTCB/C N, even if that is untrue then you can still buy MTCB/C units.
That I know. You can still buy KitKat units..

px5 upgrade

I have an older PX3 unit (i think, it's a rockchip rk3188 + 1gb ram, made by Joying) I'd like to upgrade. I've found a PX5 board: https://www.aliexpress.com/item/32820356300.html and have been reading stories about BT/WIFI not working. I'm handy with a soldering iron, so I can potentially change out the BT/WIFI module if it doesn't, I'm assuming I'd swap it with this: https://www.aliexpress.com/i/32953209958.html if I run in to problems? Also, is there anything I'd need to do to the unit before swapping out the boards? flash anything? Is there a better board to upgrade to? I've read about PX6 boards but can't seem to find em on aliexpress. In all honesty i think the PX5 would be a sufficient upgrade, since this PX3 is just stupid slow. I don't care about 3g/4g dongles, just really want something that will run headunit reloaded for android auto.

Thanks. Is there any prep to do beforehand? or is it just drop in and go? I'll have to solder on that wifi/bt board i suppose, but I mean software wise?

Suggest updating your MCU to latest available. The supplier should ship the SOM with Android installed.

Do you know which one is the latest for my unit? According to the list of cross compatible MCU's it should be 2.56?
I have a new PX5 SOM for sale and also a bricked one if someone is confident using OTG mod to unbrick it. I post to UK only

Hi there as well
Please allow me to give you some advice.
1. The last post in this thread dates back to almost a year ago, so there is little chance of you getting the replies you are hoping for.
2. That gets me to the second point.
You could start a new thread in the Q&A section, with exactly that question you have posted today. Might get you some attention and ideally an answer to your question
Good luck!

Bluetoothmusic of course.
Ability to install Cams .
I dont know what elese to look at it would be realy nice if you could guide the way
I too am looking for a suggestion similar to the op.
Me's 3, looking for a head unit for a 2009 ford fiesta looking at the ownice k6 or k3 high but I'm just a bit unsure of sinking around £300 on somthing without some advice first, any would be appreciated

Not a specific model for your car, but this is an example, it's MTCD/E head unit, but could be expensive. https://youtu.be/8MEh0VV5wKA
thank you for the link. It looks very promising.
But it has not a simslot or am i looking wrong ?

Anyway to tell if MTCB before buying?

After reading mixed reviews about these things, I want to be sure they can run a custom rom, before buying. Is there anyway to tell?
I have been looking at the 8 core 64gb memory, 4gb memory from Seicane for a Chrylser 300. This one on Alibaba.
https://www.aliexpress.com/item/400...earchweb0_0,searchweb201602_,searchweb201603_
Anyone know if this can run custom rom? or a way to find out?
You want an MTCD/E/P, MTCB units are long retired. Ask seller to tell you what the "MCU" is listed as -anything starting 'MTCD or MTCE or MTCP' is such a unit.

They're all flawed, [GS] MCU Type (Factory) may still be sold by reseller Xtrons and [HA] MCU/Factory Type sold by Dasaita/HotAudio appear to be the better of the bad.
Thanks, they dont make one for my car. Thanks though.
I seen on 300 forums, there was a unit that keeps being suggested Thread goes back to late 17, till about now and all have had good results and units still work. So hopefully they have the right MCU.
