go to factory settings and enter *#hct#root#

run adb on pc/mac and try connect to hu. devices (pc and hu) should be in this same wifi network

try on pc

adb devices

still waiting for fix for xposed... i think with the release of the new joying unit with the same intel chip we should see some progress soon with this issue...the new joying rom looks like it will be an improvement from what we are using now....We just need someone to get a copy of the jy rom firmware and make it available to download...
[MTCD  Android Head Units Q&A] ikerg:
So currently there's no xposed. Hope the more people get the new units more chances to get xposed working.

Anyway...the most important thing for xposed was the Bluetooth fix...that as I read on these units it is fixed...the Bluetooth module is not tied anymore to the MCU....and any other device rather than phones (and all brands of odb2) could be paired ...is that correct?

Is the ownice C500 based on MTCD?

Is it with those new Intel cpu?
[MTCD  Android Head Units Q&A] Cid6.7:
The trick to Aliexpress is to wait until the "sale" ends I think the sellers have so many days to have the ad up and then once its up they mark down the price.

They do this over & over until the units sell, the one I have in my wish list has gone down $35 since it was 1st posted & it says they have 10 units available if they dont sell out in 2 days they'll mark down the price. :)

We don't have a version of xposed that works for these, right? I would really want to have AppSettings, so I can control DPI on an app by app basis.

Running at 240dpi is decidedly not awesome, and the radio/media/bluetooth apps not scale well.

[MTCD  Android Head Units Q&A] doitright:
Do, PLEASE, keep in mind, that you are talking across a very steep LANGUAGE BARRIER.

When you ask them if the unit can be upgraded to "android 6.0", they aren't answering the technical question of whether or not Android 6 *could* run on the unit. They aren't even answering whether there are or are not plans to CREATE an Android 6.0 upgrade for it. They are ONLY answering that there is NOT CURRENTLY ANY UPDATE FILE AVAILABLE FOR IT.

I *absolutely promise* that these units ARE capable of running Android 7.1 or newer.

And given that these are now INTEL cpus, a lot of the undocumented rockchip crap gets to fall away, which means that **WE** might be able to generate such an update without the manufacturers providing anything.

---------- Post added at 07:54 PM ---------- Previous post was at 07:16 PM ----------

This is pretty hilarious...

More about the LANGUAGE BARRIER.....

The Intel units DO INDEED have an SDCARD slot.

I'll tell you where this silly idea of no-sdcard slot came from;

Meet the JY-UL128 product page;

https://www.carjoying.com/head-unit...s-navigation-multimedia-panel-support-mi.html

It says at the very end of the "quick overview" section, "No SD card".

Let me repeat that again so it sinks in: "No SD card".

Lets consider those words very carefully, and try to understand what that means from a LANGUAGE point of view.

What it does NOT say: "No SD card SLOT".

It literally says "No SD card".

It does not ship with a CARD IN THE SLOT.

The slot, as it ships, is EMPTY.

But it is there. The slot, that is.

Look here, this is the product page for the JY-UL128N <-- N for "iNtel". Note: the one that everybody wants is the "N2" for Intel/2GB.

https://www.carjoying.com/joying-20...r-dab-obd2-nfc-bluetooth-mirror-link-653.html

If you scroll all the way down to the specifications section, it is pretty clear that "Support micro SD/SDHC (1-32GB)" and "Maps: Built in head unit or Memory card".

So yes, it does indeed have an SD card slot.

Oh, and the slot is labeled as "GPS". That really does suggest that that is where your maps go.
[MTCD  Android Head Units Q&A] ikerg:
I never said that intel units will not have the sdcaed....i did say that the model that HotAudio is going to sell me has no sdcard slot.

Is the universal model with no knob (all touch buttons)

I did have that unit for rk3188 but it died and i asked if they could have the same model but with intel / 2GB ram .... and they told me that the original sdcard slot that was present in THAT model in rk3188 was replaced by 3G sim slot for the Sofia 3gr model.

Perhaps the guy in HotAudio is wrong and there is no sdcard instead of sdcard slot.

But you were NOT in my conversation with this guy.

I asked explicitly about that ... and about how other models have sdcard slot...

I only can state the conclusion of the conversation....and as you were not there ... is the only conclusion for people close to the product.

Hi mates. I recently ordered this unit on aliexpress on AnyGo

https://m.aliexpress.com/item/32707119098.html?aff_click_id=5cf690dfa8ba4234afe84ab77f684573-1477599627746-03123-NbAAaiqz3&aff_platform=y

I had received on 26.10.2016, since then this unit gave me pain in the ass. First, all apps crashed within 2-3 minutes interval, then the item gone in lolipop logo loop. After waiting 5 minutes with engine off the device started. After again just app crashes, i contacted the seller Rain Wang and he gaved an update that partialy resolved the problem, now it crashes but randomly, it can run 1 hour without problems or just 10 minutes. Bluetooth also drops on connection with elm obd2 adapter. I didnt tested the external microphone.

Question: Does your units do the same? Or only mine, also i think i have the intel version with 2GB of RAM. I will post a picture of the version.

Can this be fixed with any custom rom? Or it's a physical problem? I must open a dispute with this problems or is a common bug of these chinese crapsh*t. Now i see the seller doesnt even respond.

[MTCD  Android Head Units Q&A] skange01:
Can you comment on your experiences with the radio reception and bluetooth streaming music quality? These two items are my biggest pet peeves with my current joying unit (1GB 7" model). Also - even though I currently don't use it much...feedback on the bluetooth mic (internal and external) would be nice. Probably would use it more with my current unit if it worked well. Trying to determine if I should upgrade. Thanks a bunch!
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
You may also want to try to copy update to gps card.boot to recovery by pressing the reset then press and hold the back button till lights flash then let go wait a sec to two then press back again now your in recovery ..wipe from there both partition and cache and apply update from sd... remember to backup apps before you wipe you want with apk extractor before you wipe ..torque, nav apps,dvr app, these are not part of original rom but can easily be restored ....
[MTCD  Android Head Units Q&A] rhetor22:
Music quality is hard to say as I just installed this into a used vehicle I purchased. The speakers are factory and one of them is blown. New speakers coming in a few days so will certainly keep you posted. I used to be more of an audiophile but think I've lost the touch :)

It's only been a few days but have not had anyone complain about the microphone. I use the corded external mic mounted up near the map lights in a 2001 Nissan Frontier. The bluetooth is... stupid. I'm guessing they didn't want to pay for a real BT module or something. There is no BT menu in the Android settings, you have to use the screwy app to do it. It connected to my phone without issue, but my OBD2 bluetooth module will not connect. I'm wondering if its better to just get a USB BT dongle. Not sure if that's an option though.

Lots of glare on the screen... but otherwise for the price it is great. It's actually very snappy, I was expecting it to be slow and unresponsive but that is not the case. Very little load times, turns on almost instantly when you start the car... reverse cam comes up right away, etc.
[MTCD  Android Head Units Q&A] vincel892:
Thanks for the review. Kinda worried that it can't connect to your phone and obd2 as well. Was really looking forward to using that feature.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
post the pics
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
you can connect to obd2 just fine you need to change the pin number to what the obd2 uses before you try to connect .....
[MTCD  Android Head Units Q&A] rhetor22:
Just to be clear- it does connect to my phone via BT. It's just the OBD2 that has the issue.
[MTCD  Android Head Units Q&A] sterod:
Okay this is very worrisome because the original poster made it seem like this Bluetooth issues were resolved. Can you try pairing a Bluetooth mouse for Bluetooth keyboard to the device and report back? If neither of these work then that means that there has been no improvement with the Bluetooth module on these new Intel head units and that would be extremely disappointing.
[MTCD  Android Head Units Q&A] rhetor22:
Tried that, didn't work. You can set the pairing name and code for the unit itself. I tried setting that to the same 1234 PIN as the OBD2 connector... did not work. Also, when you scan for the device and click add, it prompts for a PIN. So I think they are different settings.

I just tried a generic mini USB keyboard with touch pad and it would not connect. It did not prompt for the PIN. It is odd though, my 2014 Moto X connects immediately without a hitch.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
you have to change pin with onscreen keyboard and press done then it will work ....
[MTCD  Android Head Units Q&A] sterod:
USB keyboard won't be a true test as those did work with other older mtcd units it has to be a Bluetooth mouse or a Bluetooth keyboard or basically anything Bluetooth other than a phone or an OBD2 adapter. If they haven't fix this I'm done with these head units and I will go back to the newsmy carpad which worked perfectly even though it runs an older version of Android I don't care anymore
[MTCD  Android Head Units Q&A] rhetor22:
I'm sorry, it was a BT keyboard and not USB. That was a typo. I'm trying a firmware update shortly to see if that resolves any of the BT issues.
[MTCD  Android Head Units Q&A] sterod:
What we need to determine once and for all this if the new Bluetooth adapter on these Intel head units is still tied to the MCU or if it is visible to Android. The fact that you didn't see it Bluetooth menu in Android is the point of concern now.
[MTCD  Android Head Units Q&A] vincel892:
So your device can connect to both phone and obd2 no problem ?
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
i have have my unit connected to phone(note 3),bt obd2 (needed to change pin), bt headphones( needed to change pin),bt audio transmitter, and pc (to tranfer files) all at the same time running torque with no problems ....received calls while running torque..all good ..all working ..all i had to do to get some devices to connect was change the pin on unit before i tried to connect...
