[MTCB Android Head Units Q&A] typos1:
I said NO SUCH THING ! Read my post again ! I said if you put the incorrect MCU on it will not brick it, it will just mess things up, you can reflash the correct one and everything will be all right. This is not saying you can flash any MCU, its saying if you do it is easy enough to correct it.

Joyous and Klyde say it does not work and you seem to have consistently failed to make it work, so I concluded that it does not work with dual core units, apparently, as you say, Priusfan has got it to work with his dualcore though.

I dont think $80 for a processor that has twice the number of cores is too much, its cheap - factory prices !

Root it you wont regret it. Also I ve used several Android devices for years with USB debugging permanently on, never had a problem.

There are loads of ROMs on the fileserver linked to on the first page. You can use ANY dualcore firmware you like on your unit, JY, KGL, KLD, Malaysk's custom ROM, as the first page says.

There is also stuff about custom recoveries as well. Most people use Titanium though as a custom recovery means you cant update so easily.

There is no difference between quadcore and dualcore MCUs, they are the same for both !!!!

I really hope you guys can help. I have upgraded my RK3066 to the 4.4.4 with the MTC of 2.52 i think it was, and now poweramp just auto plays. I have a feeling it's built into the upgrade i did to allow the autoplay on bootup. I dont want to go back to older software but this is driving me nuts that everytime i boot up the headunit poweramp starts to play. Any help? It's the KGL unit and I downloaded the April 2015 update posted on here.

---------- Post added at 11:39 AM ---------- Previous post was at 11:32 AM ----------

This is the exact problem im having though. Even if i am not running poweramp and i shut down my car, when i turn my car on later it opens up poweramp and starts playing music. Even if i have the radio app open it plays both. But how can you turn off auto open to poweramp upon boot up so im not having the music starting every time?!!! Hopefully you can help because this is driving me nuts.

is it worth upgrading from RK3066 to RK3188?

I have a year-old RK3066 KGL model, is it worth upgrading to the later RK3188 model with the 1024 screen as opposed to the 800 ?

I noticed on my current unit when I run the dashcam and stream music, the music breaks up some of the time, thinking the CPU is a bit taxed...

I see the unixbench scores are much higher in general for the RK3188 hardware as opposed to the RK3066 hardware...

Android Version: 4.4.4_14042015

Kernal version 3.0.36+ Root@ubunto #1140

Just to be clear,

I can install any Malaysk or Coudu ROM without having to install a custom recovery by placing the rom on the GPS sd card and starting the unit? If I want to go back, is there an image of the ROM I have?

I am not doing it for root, I only want to use a better equalizer. The stock one is, as we all know, garbage.

I am not plannign on updating the MCU, but when the time comes, I can use any KDL MCU, correct? I dont have to look for a KDL2 MCU update?

Joying JY Quad Core 800x640

Hello all. Excellent thread and ROMs as always.

I purchased a JY unit, sold as Joying on eBay. Unit works well, can't complain. I like having physical buttons, so I picked this unit - only wish I could have gotten one without the disc drive. This is Item 331538935201 on eBay if anyone is interested. I loaded one of the MLD ROMs, only issue is the notification center and weather widget in there are kinda funky.

Two quick questions... What's the best way to improve wifi connectivity? I was thinking of cracking open the unit and redoing the antenna cable to have a SMA connector on the back so I can use a better external antenna... But is there any way I can use a USB wifi adapter? I do wireless and networking stuff for a living, so I've learned how important it is to have your radio directly plugged into your antenna rather than using a long extender cable.

Second question:

Where do we stand with remapping the physical keys? I have a TV button that literally does nothing, my volume knob pushes to mute (but I also have a mute button... redundant), and would like to make at least the MEDIA key go to Spotify.

Thanks for any help, or if anyone wants to know about any details from my unit, let me know.

If anyone needs hosting for ROMs, images, etc... I have plenty of servers and bandwidth available. I'd like to give back as much as I can to you guys for working hard on making all of this.

Steering Wheel Controls - KGL Model for Volkswagen

There seems to be no way for me to change the steering wheel key assignments. When I try to change it from the Android settings, I do reset but then, no matter what I press on my steering wheel, noting happens on the setup screen. There are 3 pre-defined sets for Volkswagen in the "Factory Settings" menu. They work for the most part but need some fine tuning. For example, some of them reverse the "next / previous" buttons on the steering wheel.

I have searched through this thread but found no clear answers to this problem. A configuration file for the SWC keys was mentioned in one post, but I was not successful finding it. Any idea what to do with that?

I have a S07 model for Volkswagen, 8-in screen version 1024x600, with no turn knobs. MTCB-KGL4-V2.08, Android 4.4.4. Original as delivered.

I have also tried many things to customize them, but for my part i haven't found anything to do so on the settings panel to change that.

I have been struggling with my Joying RK3188 unit for 3 days now, I think I have a defective digitizer, I hope not but well, my problem is the following. I can't seem to register any action properly on the touch screen. In fact, there is only an area at the bottom (i circled it in green on the picture) that is responsive (and not very well i should mention).

Please give me opinions, it's brand new, i have it since less than 2 weeks and i feel helpless because Car Joying is not answering anymore...

You dont need custom recovery, place on GPS card as first page says. There are loads of images going back over a year on the fileserver if you want to go back.

What do you mean about the equaliser ? - The equaliser is MCU controlled you could only have a different one by using Viper4Andoid, poweramp or similar, you dont need root for poweramp, you do for Viper.

It is best to always run the latest MCU, unless it causes a problem, in which case downgrade, problems are very rare though. You can only use a different version of the MCU you have, so if its KLD2, then you can only use KLD2 updates without problems (at least for now).

As numerous posts in the thread say, fitting a better wifi antenna helps reception. If you were feeling adventurous you could fit a different wifi card. You could try a usb wifi dongle if there is such a thing, unless you meant 3G, in which case theres loads of info in the thread. Remapping hard buttons, not possible so far, theyre MCU controlled.

Search the thread to find out how he did it.

XMTC can do auto dimming based on sunrise and sunset times calculated for the time of year and your location based on GPS info using the algorithm found here via the sunrisesunsetlib-java library by mike reedell.

If your SWCs are handled through a canbus adapter, I don't believe you can use the remapping feature in Settings.

Re: my Android Auto app.

No, there is no user interface at this time. The app just starts and hopefully goes into video mode for Android Auto.

So the only screenshots I could show would just be standard Android Auto shots you can see all over the Internet.

There will be a configuration UI in future, and possibly some controls that wrap the AA video, or can float over it.

So what is it exactly ? Some sort of screen mirroring app that mirrors your phone ?
[MTCB Android Head Units Q&A] gazdaaa:
You are saying that if unit has canbus box (one that comes with the HU) that is used to convert canbus button presses to swc (analog) that HU uses, you cant remap the buttons in the settings?

If so, why is that? How HU knows that it isn't standard swc?
[MTCB Android Head Units Q&A] leon_id:
you can take the screen off without breaking the warranty seal :) and check cables connecting screen to the mother board. there're a lot of images of internals for these devices and they all are more o less the same.
[MTCB Android Head Units Q&A] agentdr8:
From what I remember when I looked through the canbus apks, canbus signals are handled by the decoder, then sent to the MCU via serial, where the MCU decides to either pass it through to Android, or handle it directly. For SWC, the MCU probably handles it directly, and then just broadcasts the intents for those specific button presses.

Eventually I hope to build in button remapping into XMTC, and based on the initial thoughts floating around in my head, it should work with canbus swc as well. No ETA as to when I'll be able to focus on it though.
[MTCB Android Head Units Q&A] OneCheekyDevil:
A few weeks ago, i bought a new unit for my car as the last one had issues the seller didn't want to deal with under warranty and forced me to pay for a refund (:mad:) - anyway....

Take a look at the photos i've attached.

It seems we have a new maker and new firmware to add to the OP (Un-less someone could alert me if it's a re-branded JY/KGL/KLD/etc).

I want to flash a rooted rom (as there currently isn't a way to root 4.4.4 roms). Just need a way (other than TWRP - but need root for that) to back-up the current rom incase things go sour. If anybody could point out to a post that can assist me, i'd be really grateful :)
[MTCB Android Head Units Q&A] typos1:
Hmm, interesting, I like that front, its similar to the Newsmy NU3001U.

Another new make ! Wonder if we ll see a few more, or whether theyll be like YZ, MX and Roadmaster and we ll hardly see any ?

Cant back up your ROM without root, cant root without flashing a new ROM, so theres your answer. Things are highly unlikely to "go sour" just flashing a ROM and even if they did, all the software on the Android side of things is interchangeable and the same as all the other units apart from different launchers, so you d be able to recover by flashing another ROM. Its more if you like your launcher and want to keep it after root, or something that youd need a copy.

Anything different about the ROM it came with ? Does it have a different launcher, or is it like one of the others ?

You could ask your seller for an update or a copy of the ROM.

It should be in the VTS solution I uploaded to the ftp server listed on the OP. Of course those are all the MTC apps from 4.2.2, and a lot has changed since. I'll see if I have a copy of the canbus source from 4.4.4.
[MTCB Android Head Units Q&A] OneCheekyDevil:
Only reason i want to back it up is in the event that i have to return it for warranty - want to be able to make it look like i haven't been tinkering with it ;)

I've been flashing different roms with my last 2 decks and dont have any issues doing it.

As for this unit - it's just your standard 1024x600 KLD look-a-like. Nothing special about it. I only got it cause of the screen resolution primarily, it's lack of DVD (seriously, who still uses it?), and it's clean flat front (no buttons to go wrong like my last unit).

Two issues i've exprerienced with it so far:

1 - Wifi. It can see networks with strong signals. Just cant connect to them.

2 - It's only done it a few times, but the touch digitizer had a few hick-ups when i installed it. Got stuck with a hidden press on the Vol+. Quite annoying when you're driving at speed and you're forced to pull over quickly to avoid having your speakers blown. Switching off the unit and powering it back on after a minute solves issue.

One other time it did it, the hidden finger was stuck somewhere else on the screen, and i wasn't able to press anywhere else on the screen - other than the top bar funny enough. Dropping the notification bar was the only thing that worked.

Hasn't done #2 for a few days now, so lets hope it's sorted itself out :)

As I just posted on the Newsmy thread:

"Android Auto" (AA) is Googles "Big Thing" for car electronics and is Google's version of Apple's CarPlay.

There is AA info here: http://www.android.com/auto/ and for devs: https://developer.android.com/auto/index.html

On XDA, under the parent forum of this new section: http://xdaforums.com/andr...d-auto-general and offsite: http://forums.androidcentral.com/android-auto/

Android Auto has 2 main hardware components: A headunit in the car, and a phone (or tablet) running the AA companion app. You get in the car, plug your phone in by USB, the phone charges, and you get the AA screen on the HU. See links above for pics and videos.

AA is a "special environment" that goes well beyond screen mirroring. It's designed to be non-distracting, but this requires apps to have special AA support, which limits the apps that work, especially at present.

There was a LOT of excitement about AA, but that dissipated quickly when people realized they have to spend at least $500-700 for a compatible headunit, like the Pioneer 4100-NEX.

My headunit app can effectively turn a $200 tablet into a headunit, albeit with limited functions at present. So it's a much cheaper way to use, or just to test Android Auto.

[MTCB Android Head Units Q&A] typos1:
Yes, yes I know what Android Auto is, didnt realise it was in 2 sections though, just thought it was for headunits.

And there was no explanation as to what your Android Auto app was, I thought it was some sort of app for Android Auto as opposed to an app to use AA on our headunits/phones.

I ve not been able to see the point of it (other than making Google more money) if we ve got Android on our headunits already, unless it offers some particularly special features, from what you say it may do, although having to have special compatible apps seems a bit stupid.

It is only these headunits that require root by reflashing on KK, AFAIK. What headunit is it ? An Ownice or a Newsmy ?

No, unless its rooted, but you dont really need to back up - we have copies of most of the original images on the fileserver. Its highly unlikely your headunit will be bricked.

No he isnt !! His app is an Android Auto app, so its relevant in any Android headunit thread :)
