Overwhelmed. Need advice on what head unit

Hey guys. I have fairly simple requirements for an Android head unit.
Ability to load Android apps such as a launcher, Sirius app, poweramp and Google maps
CD player for the rare times
Able to tether Wi-Fi from my phone
Backup camera capable
Audio out for an amp
Auxiliary in
Sd card or usb inputs
I'm completely new to Android head units. Is there anything out there that suits my needs?

That pretty much describes all of them.
Well, except for the "CD" part. What is a CD?
(I kid)
Wouldn't it be easier to just rip your CDs and call it good?

I decided on the Avin double din unit

Which one sir? Can we have link?

Why would he buying an headunit with a outdated OS (jelly bean) and hardware (dual core and 1gb memory) for lots of money.
I have a Ownice C200, far more stable and runs more apps than for jelly bean.
If you want the latest headunit, Ownice just came out with the C500, this one runs on Mashmallow and got 4G LTE build in.

Do you talk about the avin avant 2?
Do you have a link of that headunit?

It's a stock looking unit and I'm big on things looking oem. I'm not into flashy car audio. This unit runs everything I need it to run. I've been rocking a nexus 7 tablet as my car audio and everything I use it for this head unit is capable of. I'd leave the nexus in there but I am just tired of its unreliability in high temperature, and it's out of place look.
It's for an 04 Mercedes c class. Tommy at Avin has had exceptional pre sales support replying to all my annoying questions. Got it for $399, I can live with that.

Sorry to say but this unit got crap specs. I had before similar with same spec. Maaaan it was dam annoying slow....yhhh

It will be fine. It's a car radio. Music and navigation don't require cutting edge specs.

I was frustrating with those simply tasks ?

just got a Dasaita Hot Audio V600 for a Jeep Wrangler

So i have posted several times on this board about my various Joying units, and I have a thread about my Seicane:
https://forum.xda-developers.com/an...cane-10-1-inch-android-6-0-head-unit-t3656383
However it lacked the Dormancy that Joying had and the sound wasn't great on it. So I decided to pick up a @hotaudio unit, in particular this one:
Dasaita 10.2" Android 6.0 Car GPS Player for Jeep Wrangler
I got it in the mail on Tuesday, I made an unboxing video here:
https://youtu.be/z1v2t8cSNvc
I also have it installed, that video isn't up yet. But so far so good, it seems to take most of the best features of the Joying and Seicane and mesh them together. It is also a PX5 MTCD, so it has a lot of MTCD like features that my original Joying had, so it is like a bit of nostalgia for me. However thanks to the Octacore and 2GB of RAM, it doesn't have the slowness of my original 1GB of RAM Joying unit.

How is the fit and finish of this unit when installed? I have the Joying 6.2 2GB Sofia unit and love it. Sounds WAYYYY better than that stock crap I had. Interested in this one though. Does it work with all apps, most importantly waze? One more thing where did you order it from? Ebay?

it fits better than the Seicane model I had previously. The Seicane seemed to look spot on color-wise, but the Hot Audio is a smidgen darker than the other plastic. However the Hot Audio is also harder than the Seicane, so it installs easier. Still sucks to install, but not as bad as the Seicane.
So i definitely like it better than the Seicane, and it looks much better than the Joying. I have over a year experience with Joying, so I'm waiting to see how the Hot Audio turns out.
So far, I'm loving it, everything works like a champ, Waze included. The sound quality is top notch, maybe even better than Joying

Install video is up

Thanks for the video.
My unit comes in Tuesday.
My Car is a 2008 civic SI.
The Hu is not compatible with the stock amplifier. I'll need to use a metra 70-1722 as the middle man and figure out how to integrate the stock amp.

Cool, post some pics. After seeing mine, my buddy wants one for his Camry.
I am pretty happy with mine, just one issue I need to figure out.
When using Auto Sleep, the USB will randomly not mount properly when it wakes from sleep.

My unit just came in today.
It came with a obd2 adapter. I didn't realize that it was included. It also came with a small disc, but disc was cracked in half.
Did you end up using the disc?
Also I don't have a manual lol. I rememebr you getting a manual when u opened yours right?

I know you guys haven't really had a long enough time to test the features of this unit.. but i'm in the market as a first time android head unit owner and was considering the joying (JY-UM135N2, 2 gb, sofia), but also would consider others.. is the Daisaita worth looking at?
Not sure what the price of the unit is since when I click the "buy now" link.. nothing opens. Hah.
Thanks!

You have to buy from eBay or Aliexpress.
I have both the Joying and the Dasaita.
If Dasaita can fix this one bug, then it is one to go for.
Joying has always been a good thing for me

Here is the hidden MicroSD card

Here is a video about wiring a PAC harness to a Joying.
The same principles would apply to Seicane or Dasaita. And if the default harness doesn't work with the Alpine and/or Infiniti, it will definitely work with a PAC.

Does this thing support HD Radio, by the way? I was looking into getting the universal version (Nissan I think is the universal one), but I don't see any mention of it being supported.

I am not a great reference here, I almost never get phone calls. Pretty much all of my calls are just to test to make sure it works.
However they seemed fine

Here is a video about installing and using MtcdTools on my Dasaita Hot Audio V600

What's state of the art now? MTCE units? And what's next?

Boy, did I fall down the rabbit hole! I'm prepping my 2006 GMC Yukon XL to tow a travel trailer. I wanted a backup camera, so I started looking at Sony/Kenwood Android Auto units, then stumbled across a message Dasaito head units, so I Googled that and holy CRAP Toto we aren't in Kansas any more!
Okay, so MTCB/MTCC are the older boards, and the suppliers are cranking out MTCD boards now. Got it...
I'm seeing references to MTCE in version strings, but I can't find any discussion about them. What's the deal with these? Are they better? Are they image-compatible with MTCD?
Is there anything better than the current 32GB/4GB octa-core platforms? I see references to Intel-based platforms - are they better yet?
And are there any other families of Android-based head units besides the MTC* platforms?
I'm just a tech-nerd dad with two kids who wants to go camping, but suddenly finds himself in a strange and wonderful land... Thanks!

Buy a real head unit from a real hifi car producer, like jvc kenwood sony alpine etc...
Cinese unit will never be hifi headunit. Go for an android auto one, like JVC Kw-M870BT or similar. You get good audio quality, real warranty, good performance everywhere.

This is what I'm wrestling with. The original plan was to purchase a Sony XAV-AX200 from Crutchfield. It supports Android Auto and has a physical volume knob (essential for road trips with kids). If I purchase from Crutchfield, I get the bezel surround for my truck, the PAC RP5-GM11 interface unit to mate up to the GM factory harnesses (including the Bose digital amplifer), the backup camera plugs right in, and so on. For a small fee, Crutchfield even pre-solders all the harnesses so you literally just plug the thing in.
Which leads me to a side question - do I use the same PAC unit to connect to these Android head units and mate to the steering wheel controls? I wonder if the Bose digital factory amp connects the same way... hrmm.

I should add that I have two additional motivations for using an Android head unit, both related to towing our 28' travel trailer:
I planned to purchase a standalone trailer TPMS system, but it would be great to have the head unit monitor the trailer's tires.
I use an Android app to level our trailer (put a phone on the floor of the trailer, and it sends the angular level to a second Android device), but I could run the receiving app directly on the head unit.

FYI, Those Joying units are not MTCD/E. You will not have all the 3rd party support that the MTC units have.

The mtcd/e units honestly are...a mess... MCU files and such. If you find the joying xxxP2 models....those are FYT SoM px5 units...gobwoth those...also means TWRP support and Xposed...and custom roms coming as well. The only downside is you can't install malaysk rom...but that seems to be bloated anyway. Take a look at the work done with the Intel joying...the P2 model is virtually identical to the intel save for the Px5 cpu...so lots of customoziation available

Is TWRP all ready out for PX5? Never saw it. I've been reading up on all you guys work on the Intel side, made me jump ship and buy Intel. Or is all this still in the works for PX5? Will be nice to have as a backup, and once support matures a bit more.

Well crap, I didn't realize that.
Okay, so what do I really lose by that? I can still run a third-party launcher (FCC Car Launcher, etc.), right? I'm new to all this, so it's not a rhetorical question.

Once I get my hands on a P2 unit, yes, the bootloader is easier than the Intel to work with.

Yes, you can still run your own launchers. These Chinese units have a few bug here and there. For example the Joying PX5 sleep mode will kill background services that other apps depend on, giving you unwanted app crashes. You have to find work arounds for things like that. Short on time to go in depth tonight, but feel free to ask any other questions. Though the other devs here are better suited than me.

Link to the MCU version for this Joying unit:
https://www.youtube.com/watch?v=frxm0uNSTtE&feature=youtu.be&t=1256
So guys, you've already lost me. So if I go with this JY-UO135N4PX5, basically I only get whatever updates Joying provides, and no other options - is that correct?

I'm an engineer, so I regularly experience "analysis paralysis" while trying to make a decision. I get caught up on the details, which is especially difficult in areas like this where there are lots of details, but sparse and scattered over a wide area!
I want a 4GB RAM, 32GB ROM - pretty much because the numbers are higher, which makes me happy. I want a physical volume knob. I originally looked at the Eonon GA2170. The Joying unit caught my eye because it's got a SRC button, which would be handy for quickly switching between sources.
So given that I want a 4GB/32GB unit and a volume knob, what do you guys recommend that I look for?
Back in the day, I had one of the original Rio Car ("empeg") head units installed in my 1995 E36 M3. Man, that was a killer setup. I had my whole collection with me. I had a 60GB unit, which had to use two 30GB drives because drives were so small at the time.

I would skip the n4 px5, it's a different OEM that isn't easily modified. the P2 models are the best, although currently limited to 2gb/32gb

Are the P2 units a board platform, similar to MTCD/E? Is Joying the only supplier for P2 units, or are there others? You mention that the P2 platform is currently the best - best in what way?
Here's a Joying P2 unit with the front panel I like (but limited to 2GB as you note):
https://www.joyingauto.com/joying-h...em-touch-screen-head-unit-with-bluetooth.html
I suppose I could wait until 4GB units start becoming the norm. Great information here, guys. Thanks a bunch. I'll make sure I give back to the community by documenting my install (and my on-the-road towing experiences!) once I get to that point.

The OEM manufacturer is FYT (fyttek) they have a SoM module platform. The Intel Sofia by joying uses their 5009/6021 modules...they make a variety of modules for different resellers. Their latest SoM is the 6026 which is similar to the 6021, but with a px5 instead of the Intel. They are big in China, though a few resellers do use their platform to sell globally. They are not MTCD/E, they use their own MCU. I've had MTC units, as well as FYT based units, I like the FYT stuff better for the moment. Easier to work with.

I prefer my $299 Pumpkin 8.0 unit to my $1100 Alpine AA unit.

Same here, though I'm sure the audio quality on the Alpine is superior, functionality is night and day between them.

I wouldn't say the audio is hugely better. I have two setups I have done for my Jeep and F150 in the past 3 months.
Jeep: Alpine i207-WRA, JL HD905/4 Amplifier, JBL GTO609C Premium 6.5-Inch Component Speaker System - 2 sets, Rockford Fosgate Prime R1L-2X12 2x12" subwoofer box
F150: Pumpkin 8.0, Rockford Fosgate P1683 6x8" 260 Watt 3 Way Car Coaxial Speakers Audio - 2 sets, Rockford Fosgate P400-4 400 Watt 4-Channel Amplifier, JL 12" PowerWedge, JL Audio tweeters
The Jeep setup was over $3200, the F150 about half that (my goal was under $1000, but then added the PowerWedge subwoofer) - (prices include installation)
Using XM Radio in both the results are I have more lower end bass in the F150 due to the sub setup (and a Loudness setting that appears missing from the Alpine unit) and both have the same crisp sound. For streaming I feel the results are also the same at normal volumes.
Where the difference is, if you want to really crank it up the Jeep will go way and above the F150 with the dual 12" subs and better amp. But the reality for me these days is not cranking it, its just enjoying it without making my hearing any worse for wear than it already is after years of doing these kinds of systems.
I would gladly spend half what I spent on the Jeep.

I've spent too much time browsing AliExpress auctions, and I really like the button layout (with SRC button) of the Joying units. However, the only 4GB Joying unit with that button layout is the N4 (JY-UO135N4PX5) unit. The P2 version of this Joying unit comes in 2GB only.
Do you think the 4GB/32GB unit in the following AliExpress auction is a hardware clone of the Joying N4 unit?

Look at the D771A XTRONS unit. I got one, seems substantial, works well. Octacore, Android 7.1. Just installed it. I got mine off eBay when they had one of their 20% off everything sales. Happy so far. Waze works fine.

Yeah, but XTRONS seems to be one of the better known brands. It has the latest version of Android I could find in a 1 DIN unit, and had the features I wanted, especially the understated looks. No flashing lights, logos, etc. The screen mechanism is solid, smooth, with no free play. The touchscreen is responsive. So far, so good. Just keep your eye out for eBay sales.

It has to be a flip out, or it will hit my hand when shifting.

I've had a couple quad core 2gb flip out units and they all have some quirk or other. I have a Hizpo one right now and its pretty slow to start up as well as GPS. It does work though and has good sound. I was going to try that xtrons one next.
I wouldn't buy my Hizpo one again even though I paid ~185 USD shipped which is about as cheap as you can get and still get 2gb ram and 32gb rom. Can get a 16gb rom a little less but I say go for that xtrons.

Hi, can someone help me, i need backup mcu for my cyclon mp7101A, who can help?
Android 8,alwinner t3p1

Which Unit??

hello all, new here although i have ready many posts.
I have posted in another forum about head units, i have a Ford Focus 08 model so have joined the ford owners club forum for advice but i think some of my issues would be best answered in a place like this.
I have recieved some good feedback but i think i may have exhausted them with particular units.
I seem to have found some answers to my original post but have now dwindled my choice down to 3 so i need more help if at all possible...
so my post today was about how i have come to the choice of these 3..
XTRONS TE103AP
or
EONON GA2168
or
EONON GA2168k
The XTRONS is the top spec i can find on a 10" screen which could be overkill for my focus but it looks great in some vids i have seen, its also the only 10" that has 4gb RAM and 32gb ROM with octacore and Android 8.0 which was reccomended above so it has pretty much got me. the screen is detachable although slightly more longwinded to take off than some pumpkin and eonon models of similar size that i found. Also being black friday/cyber monday weekend i could get it with a fair whack off the price (£240ish on their site). My only worry is it doesnt look like it comes with the CANBUS adapter, i also am not too familiar with what that even is, is it just for steering wheel controls (which i dont have) or is it for the stalk aswell?
As for the EONON GA2168, that screen is better detachable and is also octacore however it is only Android 7.1 (is that a major difference?) its also only 2gb RAM and not 4 (again not too sure about this, would a car stereo really benefit from more than 2gb? This also doesnt seem to come with the CANBUS adapter but does come with a free rear cam or dash cam and is £247
And finally the EONON GA2168K which is very simlar obviously but is only 16gb ROM and again 2gb RAM but this time with Android 8.1 but only quadcore processor without CANBUS and also comes with free cam of my choice and is cheaper at £217
Both XTRONS and EONON offer similar spec stereos that will fit right into my hole that are only 7" however but do for some reason come with CANBUS decoder/box (is that the same thing?)
So im swaying toward the XTRONS, better spec and all that but will i need to but this CANBUS thing? Any help would be greatly appreciated, sorry this was a bit longwinded but i have spent many hours now researching/spreadsheeting/doing my missus head in with all this now and want to purchase while these deals and offers are on. Hopefully some of you may have experience here.
Thanks in advance for any input :good:
understandably i cant post links to the actual units or my original thread on the owners club but hopefully some of you will know which units i am refering to. Thanks

I have the ga2168k from Eonon...
Had it only a short time now but so far I love it.
Now, I'm using it as a daily driver in a Ford f550 superduty.... not entering it into a show...going to car club gatherings or anything of the sort. I wanted it because I needed GPS, hands free calling and that 10.1 BIG display just fits a Ford F550 well as it is a lot of truck.
Perhaps the more memory one may be better for you if you are watching things on it... or doing some crazy things with it... for a simpleton like myself, it's perfect.

Which did you go for in the end?
Im pretty much in the same position as you, torn between which 10.1 to go with... Pushing slightly more towards the Eonon GA2168K

I just installed a GA2168K yesterday in my 2006 GTO.
One thing I noticed in the included harness adapter is they have constant battery power and accessory power swapped.
Installed it with their R0008 dash cam that came with it. No DVR app. Finally found the main config menu (hidden by password 8888) and enabled DVR.
It does not detect the camera. it was working fine with my GA2170. Went to their website and was looking to see if they had a different camera available, and that is the only one. However, on the R0008 camera product page it gives a list of HU's it isn't compatible with, and the GA2168K is one of those. Sent support an email, hopefully will have an answer Monday on that. The other frustration is that half the settings they show in the user manual and online, aren't showing up in the actual menu's. Hoping they can send me a newer Firmware/OS that enables those... And finally, there is no seperate control for subwoofer like there was in the GA2170 Looks like I need to buy the remote amp level control and run a new cable to the trunk
Another issue... It is advertised as having 18 FM presets and 12 AM. It only allows me to store 6 of each...

Dears,
anybody tried Eonon GA2178 - 10" Android 9 Head Unit?
I'm actually on Eonon GA2168K - 10" Android 8 Head Unit, it's a good device with minor problems.
Anytime developers fix a problem they introduce an other problem and there's no community support for MTK chipsets.
Because of this I'm evaluating the new Eonon GA2178, that is quite similar but based on Rockchip chipset.
Tks!
