[MTCB Android Head Units Q&A] typos1:
I dont think you understand me - theres no reason why it wont flash other than its not downloaded correctly or its for a quadcore processor (if it was for the wrong screen type it would still flash). The option to clear cache is not in the version you have, thats why it doesnt appear, besides, you would normally flash the then wipe data once or twice - after flashing you ll have a newer recovery and the wipe option will appear. At the moment your problem is that it wont actually flash, hence me suggesting you try and re download and/or check youve got the right version for your processor.

Hello,

I am a new member on this forum and this is my first post. I have been reading all the valuable information on this page and it has indeed benefit me a lot.

I am looking to modify the MTCCanbus.apk for the door layout display function. By default the door status display is shown on the screen for 3 seconds when any door (including boot) is either opened or closed.

I would like the door layout display to remain ON until all doors are closed. The display should vanish in 3 seconds when all doors are closed. But it should remain on the screen forever if there is any open door.

I have done some investigation and see that it would involve modifying the doorserver class in MTCCanbus.apk.

Apologies if I have missed any posts on this topic. Any help here would be really appreciated.
[MTCB Android Head Units Q&A] cat2115:

Does someone have a solution for the brightness problem.

I'm still searching for a solution, but it seems only Malaysk or Dark Alex can fix this issue.

would it not be nice for everyone if the brightness / contrast of the display gets much better?

you still would see everything on the display during the day when the sun is shining ;)

MTCCanbus.apk

Hello,

I am looking to modify the code inside MTCCanbus.apk to change the behavior of how the door open / close graphics are shown on the screen.

After making the code changes and repackaging the same, the unit does not recognize the new apk file. Door open/close graphics are no longer seen on the unit. Copying original apk back restores the functionality.

I am copying the apk in /system/priv-app folder.

Can the experienced members here help me repackage the apk so that the updated functionality from my side can work? Please help.

[MENTION=456516]typos1[/MENTION] and all,

Would you recommend this Secicane vs Joying? I'm not sure if it's MTCB/MTCC/MTCD but based on description it's RK3188 1.6 GHz Cortex A9 Quad-core. I would like install Malaysk's ROM

Or I should just go with 8in Joying since lot members having Joying. Thank

2 Mod Ideas

Hello,

I have 2 ideas to mod the standard APKs in the head unit.

1) MTCCanbus.apk

This displays the door open/close graphic for 3 seconds and then removes the same from screen. Thus even if a door is left open, there is no way to find that out from the head unit screen. We can modify the canbus APK to change the functionality. The door open graphic should remain on the screen always if a door is open. The graphic should disappear after 3 seconds ONLY when all doors are closed.

2) MTCBackView.apk

On reverse camera screen, this app super imposes reverse trajectory. This reverse trajectory moves in real time along with steering wheel movement. However, the movement of trajectory is not accurate at all. The reverse trajectory maxes out on both left and right with just 45deg angle movement of the steering wheel. Can we modify the reverse trajectory display calculation logic to make it more accurate? I think the calculation in the APK code has to be modified to max out at 360 or 720 deg rotation of steering wheel on each side.

I think both the ideas can be coded as Xposed modules. I am trying for past 3 days to do the same, but am not able to get my Xposed sample modules setup correctly on my PC. I request experts here to help create these modules for XPosed. I am sure this would help many members here to enjoy even more from this beautiful head unit.
[MTCB Android Head Units Q&A] agentdr8:
My reverse view was always static on my MTCB. I wonder if this is because of your specific vehicle's canbus integration? Either way, if steering position is part of a calculation method, then it can definitely be modified via Xposed.

Hit me up via PM if you have specific questions or issues surrounding Xposed and I can try and help out.
[MTCB Android Head Units Q&A] typos1:
Seicane and Joyous are just sellers, they are not manufacturers or developers.

The "Seicane" unit in your link is a KGL unit, KGL (Kai Ge Le) are one of the largest manufacturers, so are Joyous (the units Joying mostly sell) and Klyde (KLD).

Personally I would recommend a Klyde unit, but it does not really matter because, I am sure you must have read that they are all pretty much the same inside, only minor differences - ROMs are interchangeable between units from all manufacturers, its only the MCU part of the software that is different.
[MTCB Android Head Units Q&A] cat2115:
Thanks. It just scare me it might not work with Malaysk's rom for RK3188. But based on your statement, it should. Now, need to pick b/t 10in or 8in screen lolz. Which one would look good, Is KLD only made by Pumkin? If so, they not are for '13 Highlander for 8in screen.
[MTCB Android Head Units Q&A] typos1:
Pumpkin do not make ANYTHING !! - they are not a manufacturer either, they are just a seller of Klyde (KLD) units. Plenty of other people sell Klyde units, including Klyde themselves on Alibaba and Aliexpress.

I think it would be a good idea for you to read the wiki.

I cant advise what looks best, thats for your own personal judgement.

I have a MTCB Jy headunit. It takes forever to connect to Wi-Fi. Wi-Fi seems to connect when it wants to. It seems to have been that way through every update I have done. I am able to link up my Bluetooth odb2. Torque won't see it and says that Bluetooth is asleep. I am currently at MCU 2.73 after an update from 2.16, and KitKat 4.4.4. What do I need to do to make everything work correctly?
[MTCB Android Head Units Q&A] typos1:
I would search the old thread or MTCB forums for the BT issue cos thats entirely separate.

For wifi, changing the MCU can help, all I can suggest is try them all. I d also recommend the Lollipop update., although that wont necessarily help the wifi problem.
[MTCB Android Head Units Q&A] Maverick923:
Thanks for the info. I wanted to update to Lollipop, but I don't see any version for my unit. I believe mine is Dual Core MTCB JY and the ones I saw are for Quadcore.
[MTCB Android Head Units Q&A] typos1:
L isnt available for dual core, you could buy a quadcore SoM though.

Another question: should I get HU (KGL) 5.1.1 or 4.4.4? And I'm just afraid 5.1.1 HU came with MTCD because I heard it's not good compare to MTCC/MTCB. The sellers hardly meantion what MCU besides just saying RK3188. How can I tell without having the unit in hand?

Would like to get KDL but their is none for 2013 Highlander 10" screen.
[MTCB Android Head Units Q&A] Maverick923:
Thanks for the info, I did not know you could do that. They seem kind of pricey. I am just wondering how much better will the unit be with L. I am not sure if it is worth the upgrade.
[MTCB Android Head Units Q&A] typos1:
Get 4.4.4 - they are cheaper and they are exactly the same hardware as MTCC 5.1.1, so get 4.4.4 and upgrade to 5.1.1 using the upgrade from the fileserver in my signature.

It will be faster and more up to date, plus you will get more (16Gb v 8Gb) space on the ROM.

Thank you for you input. Based on your experience, knowledge, and opinion, which one is good with stable ROM from Malaysk.

Selection #1

http://www.seicane.com/seicane-s121...-16g-flash-mirror-link-obd2-backup-camera-dvr

- Intelligent pure android 5.1.1 operation system.

- RK3188 1.6 GHz Cortex A9 Quad-core processor with great performance

- with 600Mhz Mali-400 MP4 GPU, It supports dual-screen display for the highest resolution of 2048*1536.

- Hard Disk: 16 GB INand Flash

- RAM: 2GB Samsung DDR3

- Screen: 10.1 inch HD 1024*600

Note: I do not know if this is MTCC/MTCCB/ MTCD

If this is good, could I flash Malaysk ROM 4.4.4 since his 5.1.1 isn't stable as of yet (I assume)???

Or selection #2

https://www.aliexpress.com/item/10-...o-For-Toyota-Highlander-2011/32338657742.html

- 10.1 Inch, HD 1024*600

- support 32GB External

Note: I do not know if this is MTCC/MTCCB/ MTCD

Thanks
[MTCB Android Head Units Q&A] typos1:
They are both KGL units, the are EXACTLY the same !! The only difference is that one has had the software updated to 5.1.1.

As I have said ALL MTCB and MTCC units from ALL manufacturers use the same internal components they are ALL RK3188 so they all use the same Malaysk ROM, so do the KLD ones, and the JY ones they ALL use the exact same SoM !!

Buy the 4.4.4 because you can upgrade to 5.1.1 yourself and it is cheaper, plus as you want to avoid MTCD, you will be certain it isnt MTCD as they never had 4.4.4.

Hi,

after testing 4 USB dongles without success i ordered the one the manufacturer of my hu sells on amazon... WFirst time that my MTCC-KLD6-V2.95 running with Booroondook's lates 5.1 recognizes the dongle as 3G !!! So after a little while i can see the 3G symbol in top of my screen. Everything looks like connected to the internet, the dongle blinks green. I followed the wiki and installed "Mobile Network Settings" app which also lets me configure the dongle.

Curious: EVEN if the 3G symbol is there, i am NOT online... What's wrong? Something with the routing? Browser says "offline", every other app also... Does anyone has an idea?

"4.4" will confirm that its MTCB as MTCC is 5.1 only, but MTCC 5.1 units are physically EXACTLY the same as the MTCB ones.

The only reason I can see is if they are much cheaper as you can upgrade to 5.1.1 yourself,similary you can downgrade from 4.4.4 to 5.1.1 yourself also.

Why are you so set on having 4.4.4 ?

The unit in the link you posted is NOT MTCB or MTCD or MTCD !!
[MTCB Android Head Units Q&A] cat2115:
[MENTION=456516]typos1[/MENTION]: Maybe because of MTCD. I thought MTCD isn't good or very buggy?? Unless I get it all wrong.. I'm so lost.

Sellers who sell 5.1.1 said their unit is MTCD.
[MTCB Android Head Units Q&A] typos1:

Hey guys, could anyone recommend the lowest cost yet still good quality universal 7" unit on Aliexpress?

I had a 2GB RK3188 1024x600 4.4 MTCB unit from HotAudio and it seemed to handle most things pretty well. The newer units seem more streamlined with less connectors in the back. Have they cut more corners in the newer hardware? Are the MTCD MCUs really better? The audio quality and radio reception on my MTCB wasn't so great. MTCB I understand still has the most mature ROMs? Are MTCD ROMs unstable?

I'm curious what the current recommended unit is at the lowest price on Ali. Grateful for any advice!
[MTCB Android Head Units Q&A] typos1:
A 2GB RAM MTCB one ? None exist AFAIK and I ve been following this thread for 3 years. Can you post a pic of your settings/about screen ?
[MTCB Android Head Units Q&A] rcll:
Yes I can get a screenshot of settings and post tomorrow. It was a $30 upgrade from 1GB to 2GB by Hotaudio's factory store on Ebay.

There is an Aliexpress coupon promotion ending today so I was wondering if someone could link a good 7" universal unit?

I see the lowest price 7“ pure android HUs going for around $150 with free shipping these days compared to $300 I paid before, but they look smaller than my old MTCB Hotaudio model 2100 with fewer connectors on the back and I wonder about the hardware quality on these new designs. In streamlining are they cutting even more corners on the hardware?

Is MTCD the current recommendation for price/performance(hardware quality, stability) if you were you to buy a unit today?
[MTCB Android Head Units Q&A] typos1:
I cant comment about the MCTD units really, I did read they were less stable when they first came out, but I m sure that would be fixed now.

As for MTCB, Klyde has updated the MCU software to MTCC, instead of making MTCD units, and there is Lollipop now for MTCB and MTCC. I dont have problems with sound, its not the best but I dont consider it particularly bad, plus the sound seems to have improved after some of the later MCU updates (now on 2.85 for MTCB KLD and 2.97 for MTCC KLD). And theres also 7floor's sound mod for MTCB/C which, with 2 wires hands audio control to Android, normally the MCU controls it.

I would read the MTCD forum to get an idea of what people are saying about them now if youre interested in one.

Have you got any photos of the actual SoM itself aswell ?

Now it looks like i cant install any custom rom, since i dont have a MTCx device.
