Hi Guys,
I found a non-branded HU in aliexpress with RK3188 CPU and 2 GB RAM, an updated Amplifier IC 7851 and running android 7.1.1. This is the link- https://www.aliexpress.com/item/And...32812654291.html?spm=a2g0s.8937460.0.0.RS7tIA
I am planning to get this one, I was closely following the XDA threads on Androind HU for some time. I got a plethora of info, but I still need to clear up some doubts, hopefully you guys can help me to get my doubts cleared. Please let me know if my understanding below are right:
(1) If one is not so worried about the technical support then branded non-branded HU doesn't matter right? As far as I understood, the internals are same for most of the HU. For e.g. there will be many brands coming out with the same spec as above, 2 GB RAM, RK3188 (PX3) CPU and the firmware can be cross flashed? Or atleast we can flash the malaysk rom irrespective of the Brand/Vendor, if the internals are the same?
(2) If there is something that is going to differ that would be the MCU (and yes screen resolution). Am I right? However, we can flash Malaysk rom irrespective of the MCU?
PS: I am rooting and flashing ROMs since the Samsung Galaxy S2 days, but Android HUs are a little different so I thought- "When in doubt, ask"!
Thanks in advance, guys! Please let me know anything else I should be taking into consideration before buying the above mentioned HU.
Cheers,
Rahul U S
Guys, your response is much appreciated. I just want to be sure, so asking.

The unit you linked to is pretty much the same as the one being discussed here,
https://forum.xda-developers.com/an...t/dasaita-android-7-1-1-headunit-px3-t3588871
You would probably get more support going forward if you went with the PX5 octa-core version.

what support?
PX3 has 2 custom ROMs (malaysk & hal9k), plenty of mods, xposed support, etc...
PX5 has 1 custom ROM (only malaysk's, but with half of the features available on PX3 version)
Intel Sofia has no custom ROM
go figure...
@s.rahus: go for it. 2GB ram is a winner and upgraded TDA7851 is the cherry on top.
not sure if malaysk's 5.1 rom can be flashed on this 7.1.1 unit and yes, has nothing to do with MCU, that needs to be vendor specific.
Thanks much, guys!
Well, that seller is not responding at all, I would probably go with the below one. Anyway, the brand really doesn't matter. So I am trying to find a seller who responds well and something that is reasonably priced.

Pick another one, this one doesn't have upgraded amp chip, it's still a 7388.
No need for 7.1.1, find a good one with 6 or even 5.1

Hey, thanks for spending time and helping me out man, really appreciated. However, I could find just that seller with 7851 and he/she is not responding at all. If you find one with 7851, please let me know. I need the similar to OE looks and would love to have the android 7.1.1.

Found one with IC 7850. From what I read 7850 and 7851 are same. Check this out and please let me know what you think- https://www.aliexpress.com/item/4-C...32691433062.html?spm=a2g0s.8937460.0.0.73gTna

Hey bud, I am going with this one. It seems to have a better Radio IC chip as well, which claims to give a better radio reception than the TDA 77xx.

There are no 'better' tuner or amp ICs in these, the better is so insignificant its not worth worrying about. If you want the best audio amplification, use external amps. Regarding the tuner, you can install an RF amp at the antenna, but that doesnt overcome the shyte selectivity of these units. Best have a decent antenna and accept the hit-or-miss quality of the tuner.
I suggest buying a HotAudio, witson, joying or xtrons as they atleast have some support, even if second rate compared to major brands.

Thanks! Valid point. I have heard that the support from the above brands too are nothing to write home about, however yeah some support is better than no support. Unfortunately, I cannot find the one I need with these brands. I am taking a chance and trying my luck. Let's see.

MTCD is MTCD, they're all based on MTCD reference design with some minor differences. For context, I have a JY (originally px3 1GB) with latest HCT PX5 2GB and HA 2.56 MCU.

@Topfar, as both RK3188/PX3 MTCD and RK3368/PX5 MTCD units are being made (including developing N for the RK3188/PX3 BEFORE the RK3368/PX5 gets it) then theres no reason to suggest that "support" is going to be better for the octacore ones, but basically the only support your ll get is from XDA, whatever MTC unit you buy.

Yes, I had an MTCB unit with the 7786 and then one with the 6686 and the 6686 is deffo better reception wise, wit a boosted antenna I get lots of stations.

That one has pics of MTCB/C SWC screen, not the MTCD one, guessing thats an error, unless theres N for MTCB/C coming, probabaly not, unfortunately.
Anyway, currently there are a few N ROMs for RK3188/PX3 but theyve been labelled as experimental, seeing as units with N are now actually on sale, a full N ROM for RK3188/PX3 cant be far away . . .

Thanks for all your inputs, appreciated! I have decided to go with this one, with amp IC 7850 (same as IC 7851) and NXP radio IC. By the way, what do you mean by SWC screen (the physical key layout)?

The screen that shows the functions you can assign to the SWC is from an MTCB/B unit, see pic.

My guess is that they just edit and reuse the existing photos (of course superimposing the user interface). Have a look at the physical key layout as well, I think that too is not updated?
Will ask the seller anyway.

Yeah and its probably MTCD cos it has the launcher without the weather and with speed boost/amp//brightness etc.
