DIY 2DIN project

After reading some reviews, I decided I could piece together a head unit that would give me a solid hardware base.
Hardware list:
Odroid XU4
Lilliput 669gl
Bybyte 2DIN case
Sure Electronics 4X100 amplifier
Various Dongles for BT, GPS, Radio
Mini-box Dc-Dc USB PSU
There are three things I need to resolve:
1) Audio. The screen will be fed HDMI. Am I better served to use the hdmi for an audio source, or a USB - DAC?
2) FM radio. I downloaded SDR touch. The software is interesting, but no-where near vehicle operator friendly. I'm having trouble finding an automotive style alternative.
3) The USB Dc-Dc PSU has "Automotive" mode. That leaves me needing away to trigger shutdown from the XU4. I've only researched this lightly, but I was hoping for a suggestion on how to go about this.
Any input is appreciated. I hope to have the screen and case in the next few weeks.

Well, you beat me to it. I have had intentions of creating a DIY thread for a while. I was waiting to make a little progress before posting, but we can use this as a collaboration/discussion area, and hopefully it will develop into some software solutions.
I too have been meandering down this road for a while. After some pretty active work on the Newsmy NU/NR units, I finally reached a breaking point. My Unit is suffering pretty constant reboot/lockups and I'm no longer interested in compromising on my goals.
I've ordered some similar components and am hoping to start bench-testing some stuff soon. My list:
Inforce6450 SBC (Qualcomm Snapdragon 805)
Raspberry Pi 3 (To be replaced by the Inforce when it arrives)
Eleduino 10.1 1080p LCD/Capacitive.
Cheap NANO-SDR
for a case I'll scavenge one of the several Chinese headunits I have around here.
Power-supply - hadn't ordered one yet - I like your suggestion - will investigate.
So some thoughts on your questions:
1) For your/our purposes, I would look to a USB-DAC. Especially if you can offload the audio processing. I'm a little worried about the CPU/horsepower of some of these boards (esp my RPI 3 - which is I why I ordered the Inforce)
2) We will write our own radio front end. Shouldn't be difficult. While SDR touch is not open source, there are a lot of open source examples that should be helpful. Could even use the Newsmy radio source as a starting point (although it's not terribly pretty either)
3) Not sure about the communication abilities of that PSU, but I had planned on using the GPIO's of the SBC to perform some basic signaling (like tripping a relay for USB power, sensing ACC vs 12V, etc.)
Looking forward to seeing other's approach.

Awesome! Be warned that I'm a complete and total novice. I like to repurpose things more so than create my own solutions. I hadn't even thought about the GPIO to signal shutdown. I will start researching this.
I'm going to be pushing the limit on what I can fit in a case I think. I was looking for a DAC without an enclosure but got side tracked. I was looking at the twisted pear products briefly.
Here is the PSU:

Project got tabled until this spring. I had a bad experience with mobile computing solutions and haven't had time to get back on the horse.
Something smart goes here

Have also been planning a build for a while to go into my HDJ79R landcruiser.
H/W;
CNC machined aluminium face plate
UDOO QUAD - i.MX 6 Cortex-A9 Quad core 1GHz
ChalkElec 7" open frame universal HDMI LCD with capacitive multi-touch
BT Dongle
Columbus V-800 usb GPS
64gb SSD
uSDC20D shutdown controller
TDA7850 4*50W Amplifier (only need 2 channels but seems 2CH don't exist)
Switches + Rotary encoders programmed to act as USB HID Keyboard via ATmega32U4
Software side is definately where I think the difficulty will lie - getting a decent interface for interaction
I want to run android 6 or 7
# android as bluetooth client - HFP client and A2DP sink support via recompile with profile_supported_hfpclient and profile_supported_a2dp_sink set to true in packages/apps/Bluetooth/res/values/config.xml)
# re-launching music at startup and playing the last track
# Fast Startup!
# Dim Screen / Dark Mode on Illumination signal triggered (Headlights on)

I had mine up and running on the bench and my 2nd XU4 has suffered a failure.
I jumped on a 4 channel 100w from parts express and a Behringer USB DAC. I also bought and modified a Ford AM FM head unit to start packaging everything.

I've been wanting to do something like this as well. However I've thought about using a sony radio, with app remote functionality. Gives decent sound quality, radio etc all controlled through an android front end.

Can you link what you are talking about?
Sent from my XT1575 using Tapatalk

That'll control the head unit, so single din could be mounted behind the tablet install. There are several compatible head units, with DAB radio etc

Anyone happen to have a link to a place to buy the stereo chassis that all the Chinese builders are using? I would really like to have one of the ones that looks like a Ford.

Which unit for VW?

I have a B6 VW Passat and am based in the UK. I am looking for an Android head unit and the more I look, the less I am sure which to get!
I want a unit to these criteria:
Must look as OEM as possible for VW
Must have physical vol control / buttons (not just touch screen)
As much as possible, it should "just work" (I would prefer minimal need for messing about)
Needs to have radio, bluetooth audio streaming and call support only - anything else is a cool bonus (I do not need a DVD drive)
Of those I've seen, I much prefer the ones like this that look standard (this is an Ownice C500 Octa core)

Any help appreciated.

I have a Joying (old RK3188) but if I would have to buy now, i would either take a Joying with the DigitalAmp (golden Backplate) or the Kenwood 516DABS.
With the Joying i had to fiddle a bit, but with the ROM from Malayk all its okay now.
Maybe it would be a good idea to wait for new Joying PX5 HeadUnits.... but nowbody knows when they will be released - just rumors.
Update:
check also the HeadUnit from VW China: its called RCD330+ and can be found on ebay and aliexpress sometimes.

Whatever you do: Do not buy from Ownice. There units are crap and they offer absolutely no after sale service.
I would recommend you to buy MTCD unit and install Malaysk Firmware on it. In my eyes that is the best combination available right now (unless you want to buy much more expensive units from Kenwood and the likes).

Stupid novice question, but how do I identify an "MTCD unit"?
Thanks!

For simple convenience, are any of the ones on Amazon UK worth buying? Like the Pumpkin units...

This Xtrons PCD76MTVA looks nice, is it a terrible buy?
Although it's probably par-for-the-course on here, I'd probably rather not install custom firmware etc if I can avoid it.

It can be hard to tell which are MTCD units. Ask the seller to confirm it. The Xtron that you linked looks like an older model with low screen resolution and only a quad core processor. You should look for a PX5 octa core processor and a higher resolution.
Regards
Kurt Lund
NB: I have MTCD units for VW from Xtron and Erisin and they both work well.

Thanks I will ask. Also looking at Joying, as they seem well thought of on here.
I have seen plenty of newer octacore ones, but they don't tend to look as good IMO. I definitely don't want one that's all touch screen.
I don't actually know how much performance matters for me - it needs to be responsive and start up quickly (i.e. just work nicely) but I'm not going to be installing lots of apps or doing advanced stuff with it - it will mostly just be used for Bluetooth audio and android auto screen mirroring.
I'm not as keen on it (due to screen size and position of rotary controls) but this is a digital amplifier Joying one as suggested by Grungi which I might just go for if it's going to work well. It has a quad core Intel SoFIA 3GR - no idea if that's good or not!

I have this one: http://xtrons.com/pb86unvp-8-hd-dig...yer-custom-fit-for-volkswagen-seat-skoda.html and it does what you want to use it for. I think you will regret buying a 7 inch model if you want to use GPS on it.
Kurt

The beast one should be pumpkin, since it at least has parrot Bluetooth. Anyway, the best option is always a pioneer or maybe the Kenwood solution for vw, but it's only available in Europe

Jeep Wrangler JK Aftermarket Head Unit Comparisons

I put together spec and pricing comparison tables of the most popular "Restyle" and "Universal/Double-DIN" Android and competitive stereo models for 2007 to 2018 Jeep Wrangler JKs. Tables include the latest Android models from Dasaita, Seicane, AIMTOM, XTRONS, Joying, Insane Audio as well as comparisons to popular competitive non-Android units. Hopefully this info is helpful to anyone researching Wrangler upgrade options

This was a great idea, but it's out of date. Would love to see an upgraded version now that head units are coming out with the PX6 chip. If you do, please make sure to include GTA in there!

I picked up Dasaita's PX6 in the list though I probably need to scrub the market again. What's GTA? (guess it's time to start shopping again )

Awesome. Glad to hear that. I'm a little pumped for GTA. I think they are a Canadian company, and they gave me straight answers about the Chinese electronics inside. They have a different option that I like for setup. Check out the stereo styles dropdown!

They look like they're doing what Insane Audio is doing by sourcing OEM electronics then putting a custom pre-load on it, dropping it in a pretty box and adding support. For many it's probably a bit more reassuring than sourcing direct from China.

You're probably right. But they answer quickly and their english (so far) hasn't been broken. I feel like I would get better support from these guys than I do Dasaita right now. Plus, I like the alternative style they offer. I have not seen that anywhere else. They said they are working on the new PX6 model. Should be out around the near of the year.

I'm not knockin 'em at all because they're alleviating some of the concerns that many users have, domestic sourcing, support and what's likely a more stable OS configuration as they stabilize on a solid build with much less frequent updates (where you're likely to pickup bugs). My biggest issue with Insane Audio is that they're SUPER slow to update to current OSes (at last check they were still on Android 6.0, even for their PX5 platform) and they charge an arm and a leg for what amounts to only minimal value-add. GTA seems to be much more reasonably priced given what I know about the wholesale costs of the base hardware.

Nah, it's cool. I don't know them, but I get a little bit of a warm fuzzy from what little I've seen. I would look into Insane for sure, but 1) the price is just too much, and 2) the screen is too small now that I'm spoiled with a 10.2". I love that theirs is waterproof. But I spoke to them a couple of months ago, and they said they have no plans to do a new version for the JK!

I just took a look at the GTA head unit, and it looks really nice. I did notice that their FAQ here https://www.gtacarkits.com/faq-android/ states that:
Can you update the software on GTA Car Kits Android Stereos?
There is no software updates planned, unless there is a software bug that needs to be fixed. The software has been tested for a long time to be without any bugs, hence there is no software update planned for the future. Apps from the PlayStore can be updated.

That does worry me from the standpoint that their video shows a custom firmware on there that appears to clean up a lot of the Chinese firmware config apps (like steering controls for example) are different. I emailed them for clarification, and will let you know what I heard back.
I also asked them about ADB passwords, whether or not the EQ works in all modes (apps, FM, and Android Auto), etc.
There's a PX6 on AliExpress https://www.aliexpress.com/item/330...chweb0_0,searchweb201602_1,searchweb201603_52 that appears to have the same 3-piece restyle trim as GTA, which looks interesting.

JUNSUN Android system?

Hey anyone have one of the Android systems of JUNSUN?
I buying Android car system and aside of Joyning
someone recommended me about JUNSUN.
Joying processor is INTEL
JUNSUN is MTK(families on China...)
Both 2GB ram+32GB.
Junsun is cheaper from Joying in 62$
Joying price includes 4G module.
Would be great to know more about Junsun.
How are they compare to Joyning....
Thanks

Just as bad/another reseller.....perhaps post the manufacturer of the unit.

So I have the 3 options in this image.
Must say that I read good reviews about Joying.
But from the other hand I still want to know:
From the 3 options which gives the "best for bucks"?
Another thing that should be considered: updates.
If a manufacturer does not publish rom updates I think it is big no-no.
Or you (all of you...) think that all of them are just as bad as another. SO better just pick the cheapest in list.
Thank you!

Hello. I have one question about my junsun a960. The problem is that after accidentally hard reset of my device the navigation app doesn't appear in the menu. All of the other apps apear except navigation. Do you have any solution that will help? Should I root it ?

How did you managed to hard reset it? Mine is stuck on android pin, and i did not received any pin in the box

4G connection problems
Good morning to all; I have a Junsun V1 2g 32g screen with 4G with Android 9 installed in my Honda Accord VII 2.4 gasoline, everything worked correctly until the 4G without knowing why? stop working, change sim card (2 times) and still not working. Can anybody help me ? please.

A warning to all other members for a danger called Junsun:
Never buy a Junsun, never!!!
It's sad, but I bought my wife a radio from Junsun, I bought on aliexpress, I chose a Spanish warehouse. The radio worked for 4 days, then broke down. Junsun lied to me for two weeks and wasted my time, to promise send me an FW. Junsun nothing sent to me.
Then he wrote me to send the radio for repair. But not to Spain (I bought in Spain), but to China. What's more, I was not allowed to send over DHL, EMS, or any carriers. I could only send by mail. This was unacceptable to me because the mail will send it via EMS.
All this takes more than 2 months. I disagreed and I wanted to return the money. Junsun did not want send to me my money.
Now I only have a broken radio that worked for 4 days, and Chinese Junsun just laughs at me.
Of course, I bought a new radio, I won't wait 2 months.
When I complained to aliexpress, they protected junsun that this was okay.
Never buy Junsun, never!!!

Привет всем. Нужна помощь Нужна прошивка для Junsun V1 2 32 ГБ В коробке написано T392. Или прямо в нужную тему

Phoenix Automotive PX6 Units - Specs and Where to Find more info?

Phoenix recently launched a PX6 unit for my truck. It's basically the only aftermarket system out there right now that works (somewhat) seamlessly with it. Needless to say, a bunch of us bought them and there's a pretty decent following on FB for them. Unfortunately, Phoenix's support is pretty much useless and almost entirely non-existent. There are quite a few little annoying bugs that really need to be worked out and some features that really could be added. We're not holding our breath that we'll ever get a response from Phoenix.
I spent several hours searching and reading today and have a little better understanding of exactly what hardware we're dealing with and just ended up more confused.
Can anyone tell me what type of unit this is (i.e.: MTCB, MTCD, other?) so I can at least narrow down my research on figuring out what can and can't be done with this thing?
This is what we have after Phoenix's most recent updates:

The MCU type relates to the manufacturer so the MTC series is made by Microntek and you can tell by the filename in the MCU version. I have no idea who make the MCU for your HU. The SoM appears to be from ZXW but again good luck finding any info on that.

There is ZXW voice recognition software on them, so you're probably on to something there.
I'm kind of surprised that there's not more info out there on these. I was under the impression that Phoenix has been selling quite a few of them. They're really awesome little units, but they'd be a whole lot better if I could tweak a few things!

I looked at one of those when I researched my HU and at the time it seemed Phoenix was pretty responsive with support and updates. Maybe they lost their dev. I wouldn't expect them to be a big outfit probably just a couple guys in all. I picked a PX5 MTC unit for the support, customization options and the IPS screen.
Here's a couple threads you might want to keep tabs on.

Their support is mediocre at best. They've release a few updates and taken care of major problems, but there are lots of little bugs that they don't seem very interested in addressing. And there's zero documentation on how these things are setup and what some of the settings do. We get bits and pieces here and there, but there's also a huge language barrier that seems to make it harder to explain what some of the issues are.
It's my understanding that all of their stuff is made by a single company in China and they're just reselling. It's probably only a matter of time before other resellers will have the same unit and maybe that will open up some more support channels.

They probably get their units off Alibaba. I remember comparing specs with everything I could find on Aliexpress and the one I was looking at appeared to be very similar to the one made by ZWNAV. They don't have the best reputation either, another reason I went with what I got.

I think it's probably the other way around. Once the chinese manufacturer starts making units for one reseller, they'll sell them to everyone else too.
I do know that Phoenix has some involvement in the design/R&D on these as they used at least a couple peoples' trucks to probe and sniff the factory wiring for the integrated HVAC controls and the steering wheel controls, and of course, the wiring harnesses. I'm sure they just ship that info off to China for them to design the final product.
So far Phoenix is the only known vendor selling the radio for my truck. But I'm sure it'll eventually pop with others.

Any more info on these? I'm looking at the 12.1 vertical units for my Nissan Rogue. In the demo video, I noticed the passenger-side knob is labeled "teek" instead of "seek". Hopefully the final shipping units have been corrected. Anyway, just looking for more real world users of these units...
