[MTCD  Android Head Units Q&A] sodiumspain:
hi, my unit erisin es3015v came with an app called VEHICLE displaying info via canbus, like temp, fuel remaining, engine rpm, total km, etc ...

after upgrading to 1.90 version this app is gone. i think this app come preinstalled in VW units.

can someone extract the apk and share with us :)

searching i found a similar app from a joying unit , not same layout, but the info displayed is the same.

cannot post external images, but in jy-vl131 photos page it can be seen.

problem solved, you must setting correctly canbus in factory settings. Once you enter your canbus type, automatically appear the VEHICLE icon in your app list.

Anybody noticed that when using bluetooth for calls, all controls are disabled?

If I initialize a new call, then I cannot switch to navigation. Basically I cannot have a phone call and use navigation at the same time.

Though, if I am in navigation and somebody calls me, it will show only the bottom banner with call controls, so navigation this is still usable.

How I solved the problem with display colors. Erisin ES3015V

I had the same problem whit the fade colors, and the day view, and to solve this I had to buy another display (35€ more or less) you need to contact your seller or support and ask them a replacement and adding some photo with the problems on your display. I didn't want to send it to warranty in China because I was spending more!!! So I prefered to buy it and resolve the problem!

When I've replace the display I noticed that the one that was instaled was matte and was a (TFT or older type) and the replacement was glossy and darker(LCD). it comes without touchscreen so I transfer it from the older one and i solved the problem... That wasn't mine to solve, but this is a product from China what can you aspect..1 is good and 10 with problems,, you just need to be lucky!

if anyone need other information just let me now.
[MTCD  Android Head Units Q&A] typos1:
I m more of an expert in MTCB/C units than MTCD, but if the wrong resolution is displayed then I would think that you have just flashed an update of the incorrect resolution and all you would need to do to correct it is flash an update of the correct resolution, not replace your screen.
[MTCD  Android Head Units Q&A] Guerreiro_BR:
I solved by attaching the files dupdate.img dmcu.img and dmcu.ext (quoting in the file dmcu.ext screen = 4)

[MTCD  Android Head Units Q&A] screwey:
I'm pretty sure this can be achieved with just the dcmu.img and dmcu.ext files. There should be no need to reflash the dupdate.img every time.

How can i do the update from post 2 ? Kingo root is instalez, am update files to sd card. When i do to update firmware in string sayd: no update file found
[MTCD  Android Head Units Q&A] Marius B:
I write to you pm. Put file update in gps card slot.
[MTCD  Android Head Units Q&A] typos1:
This means that either the update has not downloaded properly or that the sd card needs to be re-formatted in FAT32, but sometimes the updates work better by going into recovery and updating via usb, so first try this (put the sd card in a usb reader if you have one or put the update on a usb stick), if this does not work download the update again, if that doesnt work either then try formatting the sdcard or usb in FAT32.
[MTCD  Android Head Units Q&A] cibu:
My radio is selled by A-Sure. The update seems to fit for me!? Will I lose any functionality if I flash this update?
[MTCD  Android Head Units Q&A] typos1:
No, your unit is an "LM" hence the "LM" after "MTCD".

All MTCD RK3188/PX3 1Gb RAM Lollipop units, can use any MTCD Lollipop ROM, so yes it will work on yours.
[MTCD  Android Head Units Q&A] cibu:
Thanks! All I have to do is to put the four files on my SD-Card and start the update? Or do I have to configure something?
[MTCD  Android Head Units Q&A] typos1:
Four files ? No, you put dupdate image on the sd card and it should auto detect, do not put the dmcu on it because tis an older one, the latest MCU for your unit is here :

https://xdaforums.com/showpost.php?p=73532627&postcount=811

The latest version of this ROM is the first download in post number 2 of this thread, but its just a factory ROM, theres nothing different to any other factory MTCD RK3188/PX3 L ROM, so I wouldnt bother. I would recommend [MENTION=5092263]Hal9k_[/MENTION]'s custom MTCD ROM here :

https://xdaforums.com/android-auto/...opment/rom-hal9k-mod-mtcd-head-units-t3623982

I would also read up a bit more about how to do updates because you dont seem to know, you dont wanna brick your unit !
[MTCD  Android Head Units Q&A] cibu:
Thanks for the tipps. I will have a look at the custom ROM. I have done flashing my tablet and smartphone but not my radio. But reading more is always good.

Otherwise, I would already use Hal9k most likely.
[MTCD  Android Head Units Q&A] typos1:
Are you using a FAT32 formatted sdcard/drive ?
[MTCD  Android Head Units Q&A] Tuumapea:
Yes, I am. I updated the MCU with the SD-card, installing the custom ROM does not work for some reason. Wipe'ing does nothing either...

Edit:

Got this fixed - you just need to change the file name from dupdate.img to update.img.

[MTCD  Android Head Units Q&A] hadeone:
It seems that way. Some resellers might work on software development and provide updates/tweaks but I doubt they are using the units in the actual cars they are marketed for.

---------- Post added at 04:40 PM ---------- Previous post was at 04:36 PM ----------

Keep in mind that the wiki you're looking at was written for the older MTCB units so do not attempt to flash any of the ROMS or updates. The apps might work but I havent tried any myself.

Marius B posted the factory settings passwords, root instructions and an update for his 3062 unit. That should be enough to get you started.
[MTCD  Android Head Units Q&A] conspiredminds:
Thanks for the reply!

The antenna issue; the adapter that i found on ebay (and saw on youtube as a possible fix) seems to draw power from the harness. The wire was red though, i'm wondering if this is a similar/same solution.

I have the 3188 unit so that update wont work for me. I'm also curious to know what has been patched on later versions of the firmware.

---------- Post added at 05:43 PM ---------- Previous post was at 05:41 PM ----------

Thanks for the heads up.

I believe that i'm on the 3188 unit though so the 3062 update might compatible.
[MTCD  Android Head Units Q&A] hadeone:
Contact your vendor/reseller and ask them about updates. They are the only ones providing any. At this point there is no outside development on these MTCD units. Don't flash anything you're unsure of because you'll brick you unit before you even get to use it. Don't rush to update anything if you haven't discovered a need to.

Sounds like the reception solution you found is the same one I saw. es3062 is the model number for the BMW E46 unit. You're referring to the RK3188 chip I think?
[MTCD  Android Head Units Q&A] Luxferro:
My unit also has worse reception than my stock radio. But I don't find it too bad. I wanted an android system so I can use google music/pandora, ect. So that is what I'll use most of the time anyway.

Does anyone know if there is a way to add a lock screen, preferably one that is smartlock enabled (so it unlocks when connected to my phone bluetooth)? If I have to leave my car with someone for service/repair, I don't want them messing with my google account.
[MTCD  Android Head Units Q&A] hadeone:
I remember seeing a security menu under Settings but not sure it will use the phone as the key. See if you can set your phone as a trusted device for Smart Lock, although I'm not sure if this unit supports smart lock. I've used it before on my Galaxy S5 with a smart watch as Trusted and it keeps the phone unlocked as long as the other device is connected via bluetooth.

I'll have to take a look this weekend, when I put my car somewhat back together. It's been on ramps all week, and partially apart, waiting for parts to come.
[MTCD  Android Head Units Q&A] doctorman:
I know Joying tries the head units on different cars , obviously it is impossible to check all the cars and different models. You can see in Joying's youtube channel they do actual installs in Nissan, Toyota and Volkswagen

in many cars they get the wiring diagram of the car and they go based on that...

---------- Post added at 04:44 PM ---------- Previous post was at 04:38 PM ----------

Radio reception:

1) If your car has 2 antennas you will use only one and that means less reception : solution add a great quality shark antenna on the roof

2) check your factory settings shows hte correct country settings for radio

Radio set for europe will not get any reception in USA

for USA customer always chose "AMERICA 2"

3) the ANT-208 antenna booster from carJoying will help with the FM to my experience but did not notice a difference with AM, so I recommend it for 10$ it is worth it.

Hope this helps.
[MTCD  Android Head Units Q&A] Luxferro:
The kit Xtrons sells is custom for my exact car. It comes with everything you need: http://xtrons.com/pf75attar-7-inch-...-mirroring-function-obd2-for-audi-tt-mk2.html

So it would be nice if they tested it on the car. They clearly never tested the steering wheel app, as I went back and forth then them via support emails, and even their forums. The didn't stop suggesting "canned" responses until I showed them a video of the issue, then offered to refund... say they can't test on every car. They even told me to have it installed by professional.. I'm engineering tech with almost 20 years experience.

My car already has one, comes stock. The harness from the jack on the back of the unit splits from one connector into 2 different wires, so I assume it also has 2 antenna's built into the fin? You can see the harness in the images of the link I posted above.

Thanks for the suggestion about America 2... I've been in the menu before, and I think it's on America 1. I'll change it and check it out soon as I get a chance

If the above doesn't work, I may look into getting one of those.

Overall, thanks for the suggestions :good:
[MTCD  Android Head Units Q&A] conspiredminds:
One antenna here. I feel that it's just a connection issue. When i touch the metal end of the OEM cable (where it connects to the adapter) the signal works fine. When i let it go the signal drops. This leads me to believe that it's the adapter-- maybe it's not grounding properly?

Will try America 2.

Might end up trying the ANT-208 antenna booster if that doesn't work.

[MTCD  Android Head Units Q&A] The LT:
[/COLOR]

I doubt it's a KD, I have the exact same unit and it's a MTCD_GS one. The E46 ones are all probably going to be GSes due to their front panel
[MTCD  Android Head Units Q&A] Pattond:
It's said KD on the screen, that is why I thought it was one... I guess the question is, are there any real difference between manufacturers, and are the Roms interchangeable if the are MTCD's with RK3188 build?
[MTCD  Android Head Units Q&A] The LT:
TBH, it just looks photoshopped in.

AFAIK, the Android ROMs are interchangeable but MCU firmware isn't.
[MTCD  Android Head Units Q&A] Pattond:
Marius's is an e46 unit also, and it's an LM
[MTCD  Android Head Units Q&A] The LT:
Take a closer look at his photos, the silkscreening on his buttons is a little different than those that you posted. :) Those units look VERY similar but they are in fact, different units. The unit that I have is a GS and looks EXACTLY like the NaviFly unit that you posted, silkscreening and all. BTW, it works almost flawlessly and it seems MCU is working as it should. I don't even feel the need to update the MCU at the moment. Bluetooth, Radio and other HW function nicely.

[MTCD  Android Head Units Q&A] hadeone:
I paid the extra $40 to Erisin (same LM unit as Marius), thinking they are more established but it was a waste of money. Their support is useless. Although, I think this Erisin 3062 version is based on the latest revision of the hardware. The one you are looking at may be older hardware with new software.

Looking at the ad you are considering more closely, they dont show the back of the unit. From looking at the harnesses that unit is similar to an older style with the external can bus box. I suspect they figured out how to get 5.1.1 on the older units and are selling them off. This seems to be the case for this other unit I found : http://www.ebay.ie/itm/Quad-Kern-An...792513?hash=item35ff8e73c1:g:HUEAAOSwYmZXGEMt

Not sure if any of that makes a difference to you. The one on AliExpress comes with the camera also which I bought separately for $12 so you save there. Let us know how it goes.
[MTCD  Android Head Units Q&A] The LT:
The unit I recently got was an MTCD unit, not an MTCB one, so I am not sure what you mean. It indeed has a separate canbus box but otherwise it sure doesn't have the hardware problems which were apparent with the older MTCB units.
[MTCD  Android Head Units Q&A] hadeone:
I understand they are MTCD units. I'm referring to the old style rear layout and use of an external CanBus box, which resemble the older design. I don't have any experience with any other unit except the one I have, just making an observation.
[MTCD  Android Head Units Q&A] The LT:
Probably some MTCD MCU revisions use the old rear layout. Same here, just trying to figure out the differences. :)
[MTCD  Android Head Units Q&A] hadeone:
That may be beneficial since I had fitment issues due to the new style, large 40pin socket placed directly on the back of the unit.
[MTCD  Android Head Units Q&A] TT_Vert:
Marius (or anyone w/ 5.1), can you do me a favor and go into settings | accounts | and see if you have the option to add a "corporate" email account or just POP3/IMAP? The joying I have does not have the corporate option or I am missing it.

I can only assume it was to reduce ROM size, but even that is a stretch. I posted on the Joying forum asking for this to be put back in the ROM. I wouldn't worry, we will eventually get a Malaysk ROM. They just need more donations to get the Dev a head unit.
