Head Units with non-crappy displays

Hello. I'm looking for a head unit for my 2005 Mustang. Most of the full android head units I've been seeing use a quad-core 1.6ghz cpu and have a 1024x600 display.
Can anyone recommend a unit that is better than that? I'd prefer it runs Lollipop or newer, since I plan on installing AutoMate on it, and it'd be nice to have a unified flat UI when using other apps such as Plex.
What do you think you need for 7inch display?

At least proper 1280x720. Anything material design looks a heck of a lot nicer with a higher PPI.
dont know the specs are up to your desires, but the 8 inch screen on my Joying looks pretty great:

Audio quality comparison between TDA7560 and TDA7851L

Although we've been told that units including audio amplifier with IC TDA7851L are supposed to be better than those with TDA7560, I've compared both official specs and surprisingly those of TDA7560 are slightly better... so I would appreciate some expert to clarify it...
TDA7560 => 4 x 30W at 10% THD (4 ohms), Max output 4 x 51 W (4 ohms)
TDA7851L => 4 x 28W at 10% THD (4 ohms), Max output w x 48 W (4 ohms)
Both include MOSFET audio power stage, according to specs sheet, but you can also read:
- The TDA7560 is a breakthrough BCD (Bipolar / CMOS / DMOS) technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio.
- The TDA7851L is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt25 package designed for high power car radio.
Does it means that the main advantage for TDA7851 is only to be a 100% MOSFET amp??
Which are real differences in sound between both amps in practice?? Anyone has compared both seriously??
I would sincerely appreciate your advice since I was about to purchase a PUMPKIN CN10-10301B-02A (Specific model for Mercedes A W69 and B W245)
PUMPKIN unit includes TDA7560 and seems to have better customer satisfaction and reviews than other similar alternatives that I've also considered from OWNICE and XTRONS which include the "supposedly" better amp TDA7851L...
PUMPKIN unit is one of the few Octacore units with Android 7.1 and 2 GB RAM + 32 GB ROM that I've been able to find (OWNICE and XTRONS are Android 6 units) and, additionally, it can be ordered through AMAZON prime from my city (Barcelona) with no risk, and that's something I can't do to order OWNICE or XTRONS equivalent units (Available trough Aliexpress or their respective websites).
I would sincerely appreciate your opinions regarding the audio differences and other relevant ones you may consider among these brands (Pumkin, Ownice and Xtrons).
I had previously discarded ERISIN option which seems to be more problematic and with lower quality although they provide more options than other brands...
JOYING seems another interesting option but PUMPKIN, OWNICE and XTRONS seemed better..
Thanks in advance
Hi,
As previously discussed, no discernable differences, you would be unlikely to hear any difference between these specific audio ICs and any of the MTCD manufacturers.
If you're looking at a vehicle specific unit suggest posting for user experience and searching these forums.

Best head unit to buy for a Jetta mk6

Hello, I'm looking to buy a good stereo for my 2014 VW Jetta, which is the latest in the market that has the form to fit perfectly in the console of the car, the idea is to later play with the rom and mods, I saw stereos of 8 cores and 4 ram px5, in terms of MTCB or MTCD, which should I choose?

Im looking Joying units, there are new ones with 8.1 system, Intel chip, do you recommend them? So I see the roms there are only for 8.0 with PX5 chip.
The Joying I think are the best, plus the 9-inch buttonless that looks fabulous, other brands that look are the Pumpkin and the Atoto, are the most named in the forum.

Will 4gb Px5 be enough, or is a Px6 worth the cost and lost features?

I found a Wondefoo PX5 (mtcd) unit for my Volkswagen that has the OEM look (important to me) so I don't get robbed, 720p screen, DVD, and most importantly the DSP, $270. Dasaita has the DSP with Px6 but costs about $430and is definitely aftermarket looking, and 1000x600 screen, and no disk drive.
Is it worth sacraficing features and the extra money and to get the Dasaita PX6 performance and supposed quality? Everything I'm reading points to Dasaita as the go to
You don't say which car you have but I would suggest the K3 high from Ownice just because it's a MTC PX5 with an IPS screen and there's lots of support and customization for it here. There's a pro version and it appears to be PX6 with 64GB but I wouldn't bother with it. I have the PX5 K3 pro and I don't regret buying it but I don't think it was worth the extra money. If there's a feature you would like from the pro version you can ask for it when you place your order. And ask to ship with the HU not mounted to the faceplate that will save you headaches their packaging is not the best.
I think the Dasaita has a CSN MCU. I haven't been following development on it so I'm not sure what customization is available.

Are there any units with a higher resolution than 1024 x 600 yet?

I'm looking at getting a new Android HU, but despite the newer ones having a faster CPU (I assume the PX6 is faster?) and 4GB RAM, the resolution is still a relatively chunky 1024 x 600.
Yes...1280x720
Dasaita new px6 is on this resolution

There are several units, including Joying, that offer rotatable 1024x768 screens, or 1280x720 screens. But many resellers have them now.

Which Dasaita units have 1280 x 720? I just bought a new Max6 a little over a month ago and it's 1024 x 600. I had a quick look on their store and I can't find any Dasaita units with the higher resolution. Not saying you're wrong, just that I haven't seen them, so if you have a link that would be great, thanks
