Ok it's work! It was my USB dead. I use another and I install the malaysk rom. WOW it looking very good!! But after reboot, I must activate some xpo protocol or something like that for enabling radio, software.. That normal?

Now I have only to update the MCU. The radio work perfectly like this, should I upgrade the MCU to the new 2.0.1a?

And I lose my igo primo software after while/clear reset to factory, how I get back my igo primo GPS now?

Thank you very much for helping me..

Hello, i send an email yesterday to HotAudio quick yuan (manufacturer of HOTAUDIO) for requesting the IGO gps software that i lose whit the whipe/clear all cache from the recovery menu.

He answer me today but he send me a Update rom + a MCU.

I dont know what version is because nothing is expland..

Did he NOT understand my request??
[MTCD Android Head Units General] sweetdreamz338:
Put these 2 files in the USB and update your unit from About, it will bring back all the default apps.

1 time update from ABOUT will update both ROM and MCU? But like that, i will lose the MALAYSK rom right??

I did get my device with 1.92a !

Had a few problems with the unit (unrelated in my opinion), but Erisin send me the 1.40 and I put that on.

I have not found any differences

The problems on 1.92:

I kept getting a voice message "GPS signal lost" whenever I had anything else than the Igo on the screen

And I complained about the default music app (I know now for sure this was unrrelated ;)

The problems now on 1.40:

CAN-BUS not working perfect (I can still answer the phone and hang up, the device just say "Audio" on the car display not what song is playing)

The device hangs once every week (app.)

I would appreciate if someone could explain what the differences introduced in the different MCU versions are !

Now using device as follows:

Erisin ES4507B 7" Android 5.1

MCU version: MTCD_KGL_V1.40_4 (Mar 30 2016 14:49:27), Android version: 5.1.1

Hello everybody,

I recently purchased this headunit SYGAV Android 5.1.1 Lollipop Car Stereo Video Player for Nissan Sentra Sylphy 2012-2013 Quad Core 1024x600 In-dash 10.2 Inch GPS Nav Sat with Wifi Bluetooth Radio.

The brand is SYGAV and is a vendor from China. My choice was influenced by the car I currently own and the price.

Head Unit information is:

MCU: MTCD_HH_V1.93_1

October 15, 2016 12:27:55

It's an RK3188.

I'm new to Android head units so I am trying to figure out what I can do so I'm browsing the forums. I have a couple of questions which I am hoping someone can answer.

1. I have not seen in the MCU thread firmware with _HH. Is anyone familiar with this MCU?

2. I was able to boot into recovery mode but I cannot use the volume up/down or the soft power to scroll and make a selection. My unit has touch buttons. How do I scroll and make a selection?

3. If anyone is interested I am willing to share the MCU file. How do I grab it from the head unit?

Regards.

I have an igo.apk file on my map SD card. Is that the only file you need to install the software?
[MTCD Android Head Units General] Mseirco:
I don't know what going on, before the Whipe/clear all my igo was there. Now when I try to open GPS sd card or sd card, he say, card unmount...

But my head unit don't have any sd slot. Only 3 USB.
[MTCD Android Head Units General] d00m3rbg:
Hello there, everybody

Months ago I bought a HU for my car - Renault Megane II 2005. I wanted a HU for my specific car model, so I didn't get much choice.

The HU I bought is with RK3188, 1GB RAM and MCU: MTCD_HLA_V1.73a_1.

The reason I write here is because I can't find any information relating to this MCU. The problem is it started to stuck very often, by stucking I mean, for no reason the Audio and the Touch stop(the display does not shut down and the physical buttons work but that's it and it must be restarted in order to work). It also slow sometimes( I guess, because of the Google Play Services and low RAM). It also came with a CanBus decoder, which works perfectly with my steering wheel controls, but It doesn't show vehicle info(A/C and etc.) like it said it should.

I am not familiar with flashing ROMs and updating firmware(for which I contacted the manifacturer, but got no feedback), although when I find some time I can learn a thing or two.

So my question is: Is there anything I can do to fix those things? The lack of VehicleInfo is something I can live with, but these strange "crashes" are what bug me out! Thanks in advance and sorry if I write in the wrong thread and for my incompetentence also. :)
[MTCD Android Head Units General] Spassdroid:
Hi

You probably do have an SD card slot but it is hidden. Mine is just underneath the screen and I did not know it was there until the vendor told me that's where to find it. Run your fingers around the unit and maybe you will find it.
[MTCD Android Head Units General] Mseirco:
Yeah, is what I think too. But there is no room beyond the radio and I don't want dismount radio from cockpit again. I will surely buy a offline GPS from the playstore. I saw sygic premium edition for 20 dollar. Did you know if sygic are the best offline GPS to buy on playstore?
[MTCD Android Head Units General] Spassdroid:
I use MapFactor Navigation with my Samsung Note 10.1 and I plan to install it on my head unit. It's offline and works well especially when I travel and rent a car.

The free version uses openstreetmaps and the paid version uses tomtom maps. I use openstreetmaps. Map updates are quite often.

It's available from the playstore.

Re: ZYC

I also have a ZYC, v1.95_1 Oct 30, 2016. I also haven't found any information about this, but I don't really have any need to update it. The A/C controls don't display on my HU, but I'm not really bothered about that. Your post is the first mention I've found of this MCU.
[MTCD Android Head Units General] LMarr:
Hehe , your post is the first post where I see a fellow ZYC-owner :)

I also have no real need for update, but it would be nice to know more about this MCU...

For instance: I probably have some updates as I have 2.05, and you have 1.95... But what's the difference ? :)
[MTCD Android Head Units General] Spassdroid:
Tnx from for the HA MCU update. My unit came with HH and when I updated using the vendor supplied MCU it is now HA v2.01a_1.

I'm assuming that means I can now update my MCU to HA v2.16 if I wanted to.

Inside your GPS SDCard you will have your IGO apk to reinstall... What is curious is that your GPS Card drive appears as unmounted. You will have to mount it back again.

try this app to mount it back

Once mounted, then navigate inside and look for IGO apk and install it back

New MCU for HA 2.22 ---> https://www.file-upload.cc/5j3jl1jkkidr
[MTCD Android Head Units General] ikerg:
when you pruchased your unit, it was not included any sd-card or USB?

normally all units have one sd-card slot (or two) on the front and on the back only USB ports

if one, this is called the GPS Card

if two, one is for GPS Card and other for SD-Card

So if you dont have any sd-card slot, it is normal the message of GPS card unmounted.

The sd that usually the seller includes on the unit, contains the maps and the IGO App, as other OEM apps

When you used the Wipe/Clear function while updating, it deletes all stuff that is not contained into the ROM (user Apps and user data)

THe Igo that hotAudio includes is a pirated user app that they installed.
[MTCD Android Head Units General] Mseirco:
But it strange, if my head unit do not have any physical sd slot, why Android manager and apk installer show me GPS sd card and sd card?
[MTCD Android Head Units General] moneyvirus:
Do you have on the front of your unit a 'button' which says GPS or GPS card? Sometimes its a fake button you can lift it most of the time its on the right side by a left steered car

MX is Zhuhai Witson Industries

http://www.witson.com/en/products.html

I have one of their units for a Peugeot 407 and it has heaps of issues.

I have MTCD_MX_1.81_1

I have asked my supplier to send me a firmware update but I am not finding them very responsive.

If I had some step by step instruction on how to root my device and pull out the firmware I'd give it a go.
[MTCD Android Head Units General] jimimatthews:
I tried to update my MTCD_HA unit to the latest MCU, but it didn't work. I downloaded the newest MCU for HA listed, put it on a USB, then pressed update in Settings. It finds it, and it reboots after I select it. Then in the bottom left corner of the screen there is text, as if it is loading and installing the MCU. I'm fairly sure that before it quickly flashes away the last two lines were something along the lines of:

Installation Complete
Rebooting...

But when it boots back up nothing has been wiped and I go back into Version Info and it shows that nothing has changed. My version info is as follows:

[B]MCU version[/B]
MTCD_HA_V1.63c_1

rk3188-userdebug 24062016.09:46:06

My device is rooted. There are a few issues that I would like to fix, and was hoping that this update would fix it. I have the "Shutting Down" message when I turn my car back on, with the shutdown delay, in my MTCRadio app the radio station's text only shows the first 6 or 7 characters and doesn't scroll (I've installed MTCFlatRadio in hopes that it would fix the problem, but it didn't), and in my MTCBlueTooth app the imported contacts appear with no whitespace - it shows up as "FirstnameLastname" instead of "Firstname Lastname". Other than that, the unit can be pretty slow.

Any thoughts? I feel like the Joying MCU update has the bug fixes that I want, but I don't think I can install it. I'm thinking about installing the Malaysk ROM. Do you know if that runs smoothly?

I have the Bluetooth connection problems with android 6.0.1. impossible to sail.
[MTCD Android Head Units General] markze:
They did not say specifically which issues they would address but said they are busy working on it and my issues would be fixed with the next release.

My main issues are mostly CanBus related, no reverse beepers, no steering controls, original vehicle settings menu does not respond to changes, my odometer changed from KM to miles and can't be changed back etc.

My bluetooth works fine already though.

My only complaint with the phone app is that when receiving a call it only displays the phone number and not the name of the person calling from the contacts list.

My unit is Android 5.1.1.
[MTCD Android Head Units General] dongali:
[MENTION=6137840]jimimatthews[/MENTION]

The latest MCU we have for HA is 1.63c which is what you have so it seems the update was successfully installed. Also note that only updating the MCU should not wipe any data from your head unit. We ask to do an update & wipe as a safety precaution rather than a necessity- you probably didn't wipe after updating the MCU through recovery.

Door Opening

Not sure if this is the correct place to post but cannot start a new thread due to post count. I have an Xtrons PF7590BA in my BMW for quite some time now, running Malaysk's rom it's currently working great apart from one issue i've always had. When the doors are opened and it shows the prompt on screen, the doors are the wrong way around. I have gone into factory settings and changed the door swap option but it only applies to the front doors, so the rear doors are the opposite. I know this is an issue with the MCU, maybe incorrect canbus profile or something. I've been contacting Xtrons since the beginning of the year about this and they straight up refuse to do anything, they tell me they are waiting for a response from the developer, then send me a 'new' firmware that has apparently fixed the issue (even though the firmware date was last month). I knew this wouldn't fix the issue and it hasn't. I'm now asking if they have received a response from their developer, and they tell me my unit has a hardware problem and i need to return to the reseller. I'm really losing my patience with this company all i get is the same response, change factory setting, unit is faulty blah blah blah.. I'm assuming Xtrons just get provided this firmware, same as all the other manufacturers. I know it's a very slim chance but does anyone know who the developer of the MCU is, or how i could even go about getting this changed. I'm not sending back another unit for a non-hardware fault. I've already had to return one because they insisted it was a faulty unit. From what i remember the canbus is set to BMW_Union or something like that. Thanks

My Erisin ES3015V is MTCD_LM_V1.63_1 from Jun 12 2016, so it's right to think that LM stands for ERISIN

Thanks! I've installed Malaysk's latest ROM and that fixed the Bluetooth app problem, but I'm still having the radio text problem. Can I still install the MCU update and still keep Malaysk's ROM? Is the radio text fixed in 1.81?
[MTCD Android Head Units General] Tracker95:
i don't really use the radio so i am not really sure about it but yeah i am currently using malaysk's ROM and it's fine :)

but i am confused about something, you see my version is 1.81 and the date says August 19 while the version in the main post is "HA_8-31-2016_dmcu.img (version 1.63c ?)"

so it's newer than mine so i would suggest trying it first it might be a newer version.

nonetheless here is the version 1.81

MTCD_HA_V1.81_1

[MTCD Android Head Units General] jimimatthews:
Thanks a tonne for the upload! Yeah, I tried the version in the main post, but I'm pretty sure either it didn't install, or I already have it. My MCU version is 1.63c_1 but it's dated back to June, whereas this post's one is dated August 31st.
