Really? Interesting, I've installed several stereo in my 50+ adult years on this planet. Of course, you're correct, they were made in the USA & included detailed instructions in English and didn't require 3 professional auto technicians to give up on it and 10 days to finally get it setup and functional. Oh, and I didn't have to invest $850 USA either. Totally self explainitory!

I could have bought an Android Kenwood from Crutchfield and had them install it for less!
[MTCD Android Head Units General] AeonSaber:
Why all the hate? no one told you to do any of that. Color matching just like every other radio install. I understand not being able to get the SWC by yourself but any professional should of been able to do it. took me 45 minutes to figure it out and i am by no means a professional.
[MTCD Android Head Units General] wanb1i:
I'm not really laying it on you, but trying to make a point & I guess I wasn't clear. If you have a Prius Plug-in, don't try to self install a Joying stereo Hu. No one can seem to decipher the wiring. Even Crutchfield had me buying $150 worth of cables and adapters I didn't need! Best Buy auto installers caused $399 of damage to my car and after the dealer repaired that, they wouldn't touch the SWC. They were nice enough to give me the pin out of the 28 pin connector.

For me, it was the worst product experience of my 66 years! All because the manufacturer couldnt provide instructions for the steering wheel controls.
[MTCD Android Head Units General] AeonSaber:
Does sound awful. I have a feeling installing any radio in a newer Prius or Chevy where they try to keep people from doing it will be really hard.
[MTCD Android Head Units General] leonkernan:
Is it different to all the other Prius models?

My Prius C has the 28 pin connector with the SWC, reverse and Aux input on it and it took no time to figure out which wires I needed. The SWC are just standard resistive controls.

Joying even have an appropriate adapter on their website these days.

The other connectors are the standard Toyota ones they've been using for years.

Having said that, I wouldn't trust a store installer to get anything right.
[MTCD Android Head Units General] wanb1i:
The real problem was getting the schematic. Because it's a plug-in. I couldn't find it anywhere on the net. Even Crutchfield didn't have it. The schematic sent by Axxess was totally wrong, the plug & play cable adapter for the backup camera Crutchfield provided wouldn't match up. I ended up adding a 2nd camera because of that. The whole installation experience was FUBAR!

The HU connects to my phone via BT, but it won't connect to my OBDII BT device. It sees it, but won't connect.

It also wouldn't connect to my Verizon 4g USB dongle, so I have too wifi tether to my phone.

It didn't see the 128gb SD card formatted exfat, reformatted it Fat32 and plugged it into a USB and it works fine. I'll try moving it to the SD slot today, but I'm not sure it will work there.

Now for the GOOD NEWS:

I didn't like the UI, so I tried to install Nova & Google Now, but they wouldn't allow me to add any widgets! I ended up using the CM Launcher as it installed widgets. I also was able to use ProjectM Pro (paid app) as a live wallpaper that dances with the music.

PowerAmp for my music app and it has a much better equalizer. The music sounds great!

Google Calendar and it's widget (no calendar installed by default).

Beautiful Widgets for the clock/weather widget and Speedometer Widget for the speedometer.

APW for the Contact Widget

Kodi & YouTube for video.

I then enabled the OK Google voice interface for voice interaction. I haven't fully tested it yet, but preliminary results are good.

I'll make and post a video here later today.

Overall, I'm now content with the final product. It's the process of getting here that was a PIA.

If anyone knows how to root this HU, please let me know.

To anyone with capacitive button issues or bluetooth issues (with OBDII, radar detectors, etc) or ANY OTHER ISSUES READ THIS:

For Joying 7", 8", 9", and 10.1" head units (with Android 5.1) and either 1GB and 2GB (I'm assuming only the Intel Sophia boards are compatible with this).

Joying sent me the following:

Here is the firmware update file: https://mega.nz/#!9lwWiaZb!fTqhu1UFRZK_Y-_WOPGczVrBhDxxpCXG1aABufgSkCM

Here is the video on how to update the system (no need to put it in recovery mode): https://youtu.be/XFw7EQiQgjI

Here is the video on how to connect OBDII (worked for me with an OBDLink MX): https://youtu.be/KcFcwkU5jzo

This update fixed almost every single issue I was having. Bluetooth works flawlessly now with my iPhone 6 (sounds much better than before, music streaming sounds perfect), my OBDLink MX (works perfectly with DashCommand), and my Beltronics v10 SmartCord.

The video is a little ambiguous, but here's what I did for my single-din 8" 5.1 (1GB RAM) unit today:

1. Format your microSD card

2. Unzip the update file

3. Copy all files inside the extracted zip to the root of the SD card

4. On your head unit, open the GPS info screen in "CarMediaSettings"

5. Put your SD card into the GPS SD-card slot

6. Wait for "Update Found" to pop up

7. Wait about 7-10 FULL minutes for the unit to go through the Android and MCU update process

8. Remove the SD card when prompted and wait. The screen will probably display "ANDROID" for about 3-5 minutes. THIS IS NORMAL.

9. You will be prompted to calibrate the touchscreen. Be as accurate as you can!!

10a. You will also have to set up the capacitive touch keys again.

10b. Set up the unit the same as before. Try 0000 or 1234 for the bluetooth pin to ensure everything will connect fine.
[MTCD Android Head Units General] atarantino:
So this update worked on your unit? Going to try flashing it on my new 2gb ram unit to hopefully get my OBDLink LX to work as well.
[MTCD Android Head Units General] bphillips09:
Worked perfectly. Joying says it's for 2GB units as well (mine is 1GB). As long as you have Android 5.1 and an Intel Sophia board.

This update actually worked better than my last 4.4 unit. Bluetooth connection to my OBDLink is immediate and there's no lag.
[MTCD Android Head Units General] atarantino:
Good to know. I have a 5.1 Intel board unit. Do you have the LX or MX? Wifi or Bluetooth?
[MTCD Android Head Units General] CadillacMike:
someone with 2GB RAM and an Intel guinea pig this
[MTCD Android Head Units General] atarantino:
Just tried to get the update to register on my system and no update is found. Looks like mine came with the most up to date firmware which sucks because I cant get it to connect to my OBDLink LX or any of my other bluetooth odb readers
[MTCD Android Head Units General] tsuokun:
http://xdaforums.com/android-auto/m...l-cpu-mtcd-mtc-units-intel-cpu-t3494083/page9 The same update was discussed here and some people were successful. If I understood correctly, they were 2gb units.
[MTCD Android Head Units General] Tervinder:
Just updated with the link from bphillips09 on the 2gig Intel unit, Bootlooped on the first bootup had me worried, but I reset the unit and it booted up fine the second time. JY-UL135N2

so far so good.. MCU Version date still says October 31st? Is this correct?
[MTCD Android Head Units General] bphillips09:
Did you open the GPS info screen in "CarMediaSettings" then insert the SD card? My OBDLink MX (Bluetooth) works fine now after the update.

---------- Post added at 02:02 AM ---------- Previous post was at 02:02 AM ----------

Joying says the update is for 1GB and 2GB Intel units with 5.1, you should be alright.
[MTCD Android Head Units General] atarantino:
I did insert it in the GPS slot. I actually tried with both slots, but neither one saw the card, period.....Is there a specific way the card should be formatted before the files are transferred to the root of the sdcard? Are the files supposed to be in 1 update folder from when you unrar or unzip the original archive? Or all folders expanded?
[MTCD Android Head Units General] treech:
This looks quite tempting, but i wonder if the fixed so that the built-in mic is less rubbish now so that you can use it to actually call ppl and/or speak to google.

Or does connecting an external mic fix this?

A review of this would be wonderfull :)

https://www.carjoying.com/new-andro...new-android-5-1-1-lollipop-bluetooth-4-0.html

But i think i'de have an issue with this unit, i currently have a KLYDE unit where i had to modify the harness a bit so i could use the un-amplified sound outputs since my car has an amplifier that i use.

That in itself is a different story, so i'll skip it for now ;)

EDIT: or perhaps the (sound) outputs on the back ARE un-amplified and it's just those that go in the cables of the harness that are amplified by the amp in the android unit, that would make sense :)

Also, this sorts of miss information always ***** me off, on this page is says that's it's android 4.4.4 and CPU RK3188 :\

https://carjoying.en.alibaba.com/pr...igation_Wifi_Bluetooth_car_Radio_2GB_CPU.html

But listed as an 5.1.1 CPU intel on carjoy's page.... so who knows really.

https://www.carjoying.com/new-android-car-radio/quad-core-2-din-android-car-audio.html

Confusing and very annoing.
[MTCD Android Head Units General] bphillips09:
What worked for me:

1. Format the card as FAT32

2. Extract the .rar to a folder

2. Put all the update files/folders FROM the extracted folder INTO the root of the SD card

Folder Structure:
- SD CARD
- mcu
- eom
- bootanimations.zip
- ETC

3. Close all applications in Android

4. Open "CarMediaSettings" to the GPS info screen (the one that shows satellites)

5. THEN insert the SD card into the GPS SD slot and you should see "External storage devices are being mounted" in the status bar

6. Wait a few seconds and a popup should come up saying "Update Detected"
[MTCD Android Head Units General] wanb1i:
Yup, worked on my 8" single din 2gb unit too!

---------- Post added at 01:01 PM ---------- Previous post was at 01:01 PM ----------

Worked for me! Boot looped once, reset and it came up fine the 2nd time.
[MTCD Android Head Units General] irytek102:
To the unit owners:

Now, since bluetooth is fixed, have you tried to use BT keyboard with the unit? Is it working?
[MTCD Android Head Units General] doitright:
They are already DUPLICATED. They exist both ON and OFF the screen.

---------- Post added at 07:10 PM ---------- Previous post was at 06:52 PM ----------

On ALL aftermarket head units, including overpriced big names from american big box stores.... the RCA plugs are pre-amp outputs, the harness wires are amplified for direct to speaker. The reason is because all aftermarket AMPLIFIERS have RCA plug inputs, so all you need is a standard stereo RCA wire with the red and white plugs to hook it up.

---------- Post added at 07:32 PM ---------- Previous post was at 07:10 PM ----------

Wow, those scores are pretty pathetic.

Hopefully they are just lower than ARM scores due to the benchmarks not having anything common to align to.

I honestly would have expected a supposedly "current" x86 to be in the same ballpark as a two year old ARMv7.

Just for fun, I ran that benchmark on my Nexus 6 and came up with a score of 80559 (3.68x) overall .

3D: 25838 (15.65x)

UX: 23952 (2.79x)

CPU: 22550 (2.45x)

RAM: 8219 (3.31x)

The 3D and UX are understandable, since we are comparing a Mali 450 against an Adreno 420, so not even in the same ballpark. UX is, of course, linked with 3D, CPU, and overall display resolution -- the only reason why the UX isn't closer to the 3D is because the screen on the head unit is low resolution. One would think, however, that that CPU should be a bit higher. Maybe its suffering excessively as a consequence of CHEAP RAM?

http://www.techpinas.com/2015/10/intel-atom-x3-sofia-c3230rk-vs-intel.html

Wow. Can't even think as fast as a crappy Z3735F.

I wonder if we could overclock these things? The performance difference between the c3230rk and z3735f seem to be proportionally equal to the change in clock rate. They could be clocked exceptionally low more for power considerations (battery life, heat) than for stability. Being plugged into a car, the online power source can be thought of as unlimited, so more voltage and more fans and..... Of course note that the z3735f will always be faster due to better memory bus.

Of course, the memory bus on these things also sucks donkey balls. 533 MHz 32bit single channel. Pretty sad. The z3735f has a 64bit dual channel bus at 667 MHz.

[MTCD Android Head Units General] enabl3D:
Do the new 2 GB units support 4G/LTE SIM Cards or is a USB dongle still required?

Thanks
[MTCD Android Head Units General] doitright:
Not the Joying. Hotaudio seems to sell units that resemble Joying UL128N2, but have a sim slot in place of the SD slot. Though to be honest, why would you want a mobile radio in your head unit? You carry a cellphone, don't you? Tether it and save paying for an extra and unnecessary card.
[MTCD Android Head Units General] Dusty Rhodes:
I need a little help... I currently have the Joying 10.1' 1GB head unit. The only thing I want it to do is run Waze while streaming music using Google Play. The 1GB head unit is a stuttering freezing mess when running those two apps.

Can the new 2GB units do that without turning into a steaming pile? Could someone do a thorough test? Thanks!
[MTCD Android Head Units General] doitright:
There are a total of THREE possible units that you may have. Maybe four, if they made a 10 inch MTCB.

1) MTCD Rockchip 1GB

2) Intel 1GB

3) Intel 2GB

4) If exists, MTCB Rockchip 1 GB

The Rockchip one(s) is(are) a STEAMING PILE, as you so succinctly put it.

I switched from MTCD Rockchip/1GB to Intel/2GB, and the difference is absolutely NIGHT AND DAY. The Intel ones are FAST and very usable. You can safely disregard all "benchmark" based comparisons between the ROCKCHIP and Intel CPUs, they are different architectures, so the numbers produced in the benchmarks are NOT ON THE SAME SCALE.

The Intel/1GB would be a significant upgrade for you, but if you're going to be upgrading, you might as well go with the 2GB. The price difference is definitely worth it, because you CAN'T make the change later without completely replacing the unit again.
[MTCD Android Head Units General] CadillacMike:
the Intel 2GB of RAM would have no issues running Waze and Google Play Music at the same time
[MTCD Android Head Units General] marchnz:
Have you considered upgrading RAM to 2GB in your current MTCx?
[MTCD Android Head Units General] Dusty Rhodes:
I have no idea how to upgrade the RAM in my current system. I'd give it a try if it's not too difficult. I currently have the Joying US-JY-UL134.
[MTCD Android Head Units General] doitright:
What he is talking about is;

1) impractical, since it requires desoldering and replacement of two BGA IC's. This is very nearly impossible for a VERY SKILLED ELECTRONICS HOBBYIST.

2) only slightly effective. While adding more RAM is certainly not a BAD thing, it doesn't address the biggest problem of those units; that they have one of the world's CRAPPIEST CPUs.

So if you tried to go this route, most likely you would end up with a paper weight that you couldn't even sell, and even if you were successful, it still would be LESS than satisfactory.

IMO: Not worth it.
[MTCD Android Head Units General] CadillacMike:
Just get a new 2GB of RAM unit from Joying. Looks like you have yours in a Jeep Wrangler, should take less than 30 minutes to swap it out
[MTCD Android Head Units General] Dusty Rhodes:
Yeah... I'm not soldering anything. I'll grab a new head unit tonight and toss it in after the holidays when it arrives.

I won't even bother selling the one I have now. It's such a subpar device, I couldn't pawn it off in good conscience.
[MTCD Android Head Units General] marchnz:
Thanks - not looking for an opinion from a member who hasnt actually upgraded their unit; noting that this opinion is at complete odds with the experience of those that have done it.

Yes there is risk and is small when performed by professionals. Arent you the guy who gave the inaccurate and uninformed legal advice? Please dont, opinions and speculation is just that.
[MTCD Android Head Units General] doitright:
I never give incorrect information. Time for you to take a hike.
[MTCD Android Head Units General] marchnz:
Fortunately , what you claim is easily tested. Please dont resort to ad hominems, this will result in a report.
[MTCD Android Head Units General] CadillacMike:
I dont want to join in any arguments. However I have personally had a Joying MTCD Android 5.1, and I replaced it with a Joying Intel unit, and the performance is night and day difference.
[MTCD Android Head Units General] marchnz:
Thanks - MTCx users who have upgraded to 2gb are reporting a much improved unit, a comparison between the two when upgraded would be useful.

The 2gb intel makes sense when buying new with features such as 2gb out of the box and proper bluetooth/v4, correct parametric equalizer implementation. Does your unit delay shutdown (i.e. when starting the car does the unit shutdown and then power on again or does it stay on?
[MTCD Android Head Units General] vinhZ:
Mine goes into a sleep state. From the specs from joying, it draws less than 10mili amps. Its wakes up instantly when I put my key to acc. Overnight I still have to wait for my mobile hotspot and gps to get a fix though if its overnight.

Can anyone who has one of the glass units tell me how the logo is attached? Is it on top of the glass or behind? Could it be removed?
[MTCD Android Head Units General] CadillacMike:
my 2GB unit works similar to an OEM unit. When I turn the key off, the screen and audio stays on until the key is removed or the door is opened.

When I start the vehicle the unit comes on almost immediately

[MTCD Android Head Units General] Xaadi316:
After a months use i would say joying 2gb intel is as good as i hoped...... :D it does every thing automaically (alot of stuff that i read here people trying to figure out e.g when switching from power amp to mx player the soundd playback changes and vice versa on its own :D )

Gps , blue tooth , speed all is awesome

i run google maps and mx player at the same time without any lag. i even ran clash of clans just to test its power and to my surprise it ran smooth (which a lot of old mobiles are not able to do so) of course driving and clashing would not go well :P

over all am pretty happy with this unit. hot spot and restart is spontaneous i dont notice any delays although i do manual restarts every now n then to refresh the system as will all android deivces

Do your bluetooth buttons map to different keys? Mine are showing up as the same keys as the up and down arrows. I have a 2011 wrx.
[MTCD Android Head Units General] AeonSaber:
I have a 2010. So no bluetooth buttons.

to be able to remap the blutooth button you will need to use the 2nd wire input for steering wheel controls. If you need help I may be able to find the information that i used last time.
[MTCD Android Head Units General] bass_rock:
I connected that wire but they are mapping to the same key as the down and up arrow. Unless I did it wrong.

I want to say you did it wrong. but there is no way for me to confirm it since i don't have the bluetooth buttons.
