Dont know, you will have to look up the spec.

Maybe its the same as the MTCB/C and MTC/D RK3188/PX3 SoMs ? You could start by looking at the 2Gb RAM group buy threads and seeing if the RAM on the RK3368/PX5 is the same type.
[MTCD Android Head Units General] ikerg:
Is based on a soldered ram chips. Check the people on the forum who upgraded their rk3188 to 2gb...not very easy to do.

This is great that Hot Audio is publishing the updates; makes it much easier to buy an expensive unit directly from China if there is good support from the vender.

But I have a *2014* Jeep Wrangler (the 2011-2014 Wranglers have tweeter speakers that stand up where the 2015-2017 are flat.) Is there a Dasaita Px5/2GB Ram/32GB ROM/10.2" screen with the 2014 Wrangler dashboard pieces? Where can I buy it?

The HA2158-V600 is listed in some places as compatible (hot-audio.com) but not in others (Aliexpress.)

Thanks!
[MTCD Android Head Units General] ikerg:
Contact directly to seller in dasaita store at aliexpress.

You say that maim differences are on Tweeters but they are not part of he dashboard is correct?

I can assume that...if the dashboard is the same they should be compatible....but confirm it with seller.

[MTCD Android Head Units General] tlyonstlyons:
The tweeters are part of the dash; from 2014 to 2015 they changed from small pods that stand up to larger, flat speakers. The larger speakers have a larger cut out in the dash piece that Dasaita provides with unit.

I have asked at hot-audio also but not heard back. Thanks!
[MTCD Android Head Units General] typos1:
It is easy if you can BGA solder and it is easy to take the SoM to someone who can BGA solder if you cannot.

Most of the bigger manufacturers who make these units have good support, not just HA.

I tried that and an additional applications from play store like Bluetooth pair and Bluetooth toolkit, but nothing changed.

is there another way to solve this problem.
[MTCD Android Head Units General] ikerg:
Forget any play store app...as our units manage the Bluetooth in a different way (the MCU controls the bluetootb)

My unit says it's an MTCE MCU. What's the difference between that and MTCD?
[MTCD Android Head Units General] Bose321:
It's a newer version of MTCD. None knows what exactly is new/different.
[MTCD Android Head Units General] ikerg:
It is assumed a new major software update...that not necessarily should be related with hardware change.

AFAIK developers are moving to android 8 and perhaps this update is more related to compatibility

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Android Head Units General] typos1:
Its not to do with 8 - MTCB units had their MCU changed to MTCC after a few years and both MTCB MCUs and MTCC MCUs work with KK and L.

Its just that after a few years the devs do a major update of the MCU.

If anything it may suggest that there will soon be newer units with new hardware called "MTCF".

I'm sure this question has been answered before but I can't find a direct answer. I have a 2014 Corolla and I have a button on my steering wheel called "Mode" how do I change the applications that I can switch between when I press it? Also, anyone have issues with static and humming from the stock bluetooth music app?
[MTCD Android Head Units General] ikerg:
The mode is predefined on the Rom...but with mtcdtools you can define your own mode app list

You can install ANY MTCD/E RK3368/PX5 ROM.

For the MCU you need to install one that matches the letters after "MTCD" or "MTCE", ie "KGL" "GS", "KLD", "XRC" etc.

[MTCD Android Head Units General] mrbuz:
Hello people!

The master volume of the device seems to be android independent... This is probably the reason why gps-based volume-to-speed adjusting apps don't work (like GPS Volume, Speed Volume, Smart Volume Control etc).

Does anyone know a way to tie speed to output volume using gps speed info on this device???
[MTCD Android Head Units General] ikerg:
Yes...all we know that the volume is controlled by the MCU not by Android.

MCU intercepts the intent of volume change and it changes the volume depending on source

You can adjust volume for different sources into the factory settings.

In the following post there are some mods to change volume based on GPS speed that are functional on our units as they have been programmed specifically for our units based on the available services

Thanks for the link!

But the MTCDAutoVolume (https://xdaforums.com/and...olume-t3630636) app seems to be absolete volume leveling (according to comments) and then it's not the thing that we want, as any volume adjustments must be relative to the manually set volume level!

I very much hope that someone will make an app for that to work. It would be a "MUST HAVE" app for our devices!

Theres so much information and options in these forums.

I am using graser's app

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Android Head Units General] mrbuz:
Do I have to install the whole Graser's pack or there is a standalone volume leveling app? If yes - please give a link to download it!

PS MTCD Auto Volume didn't work on my device for some reason (Dasaita V600 8-2-32). There weren't any more settings to toggle rather than the volume curves. I couldn't find any more settings to activate it. It was changing volume when I was moving the app's sliders in settings, but no changes during driving (during speed change). I believe GPS is always on as the position mark shows on the top bar and i have installed the antenna on the roof in a "shark fin" so I always have about 20 satellites in green connectivity level) .

PS-2 Could having an outdated MCU be the reason for MTCU's failure? I will check it and update if needed as I have installed the Malaysk ROM today that encourages me to keep the device updated. So far seems to be quite good. I will donate of course if it keeps working well. Though I find that some apps are unneeded and will delete them. I strongly prefer the minimalistic approach - to have only things that are practically used, not theoretically may become handy in specific circumstances once a year... This way my previous car-droid has been successfully working for like 7 years till a few months ago, when I had sold my previous car (it's still working for the new owner though - a device on Android 2.1). The trick was to refrain from expecting extras from it...

In my view, you only need a few basic things in the car: radio, music player, digital TV, navigation, browser, internet access, dvr, parking cameras and BT phone connectivity for hands free talking. That's about it. But it's quite difficult to be modest with so many tempting options out there.

A snapshot on my current device, looks like the MCU is 2.59.

What is the MTCE v2.65 https://www.sendspace.com/pro/dl/ufie8k - is this an MCU upgrade for my device???
[MTCD Android Head Units General] ikerg:
Graser's app only.

For volume there is no need for xposed framework

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Android Head Units General] mrbuz:
Thanks! Today I've got xposed anyway within the installed Malaysk ROM, though I have no idea what's good about having those tweaks yet. I hope they don't load my device too much. Tweaks often have a drawback in my experience....

I was surprised to see how easy it is to reinstall new firmware nowadays - extremely easy with one click on an "ok" prompt. Used to be a big deal in the past.

I wonder how could the respectful Malaysk developer not have included a gps based volume-to-speed control in his wonderfully tuned ROM build??? (that was another surprise to me - even obsolete OEM electronics on good cars have had volume leveling for years now)

I will install Graser's app tomorrow and update whether it works properly!

I checked the video:

1) Use the Bluetooth app (attempt 2) and not the Bluetooth under Settings menu (Attempt1). the one You used on attempt3 is the A2DP Blutooth (streaming) so that app is not needed here

2) on Bluetooth app ensure you have correctly entered the necessary code for pairing your OBDLINK device (Go to the last button on the left and configure the PIN number correctly

[MTCD Android Head Units General] typos1:
If youre talking about N ROMs, then yes - you can install any 2Gb RK3188/PX3 ROM if you have a 2Gb N device, different ROMs for the same processor have always been interchangeable on MTC devices because all manufacturers use the same SoMs.

This is an RK3369/PX5 thread though, so clearly I thought you were talking about those devices.
[MTCD Android Head Units General] zerozoneice:
thx, i tried one version but the launcher is crap, don't like it.

i'll try the latest one (20171007) and see if it's another launcher. If not i'll go back to my PX3 one from July with the JY-looking launcher.
[MTCD Android Head Units General] SkyBeam2048:
Actually the problem has been identified and a work-around is available. See here.

The reason for MAPs hang seem to be that when you have maps open and you switch off ignition the device goes t standby and kills all apps (except whitelisted ones) to avoid increased power consumption. Unfortunately the device is doing this in a very harsh manner and therefore it does not leave the apps sufficient time to shut down properly. Google maps misbehaves then if files are not properly cleaned up from the cache folder on shutdown. A work-around for this is to clean the maps cache manually. In the link above there is an app which does this. But due to security limitations an app can only clean the cache of another app if it got root access. Therefore this only works on rooted devices.

For me it also works to exit the maps application properly before shutting off the unit. But if shut down uncleanly once you might have to clean the cache again. I didn't try whether cleaning the cache in settings -> apps would work too to resolve the problem temporary too.

There are several permanent solutions for this:

HU shutdown should cleanly terminate apps. Perhaps with a timeout with forced-kill after 2 minutes or so.

HU shutdown should exclude maps from forced termination. However this might expose the unit to more power consumption in "standby".

HU could clean maps cache on each forced app shutdown. But this could have performance impacts on apps with large caches.

At the end the only clean solution is to improve the ROM to cleanly exit apps rather than killing them. Also this would not have a big drawback regarding power consumption. It does not really matter if the HU will be terminating apps in the background for a couple of seconds. The screen could be switched off immediately and audio outputs disabled. This would not drain the battery at all.

So for me this is clearly a ROM bug. It's in particular unrelated to the MCU in any way.

Btw. is there any manufacturer/seller releasing the source for their units? This would ease fixing of such bugs a lot and would lead to a complete new bunch of ROMs with improved quality and actually having bugs fixed rather than just workarounds implemented (patched DAB+ app, maps cleaner, mtcd tools... all couold be done cleanly in a repository compiling them to a really great ROM). I think legally manufacturers would actually have to release the code due to GPL base. Don't they? At least for the ROM (Android modifications), perhaps not including custom Apps like the CAN applications and the like, but they could be included as binaries or re-written.

There are so many great developers here who even would be willing to provide their experience for free to the manufacturers helping them to improve the code and develop unique features. Instead we are waiting for HCT to eventually release new binaries with more bugs we have to work-around then without having the possibility to fix the root cause of the issues. This is frustrating.

Just change the launcher if you dont like it, easy.

Hey guys,

I have a strange issue with the Bluetooth.

I have paired my phone with the unit without any problems but every time when the phone connects to the unit, I get the "in call" screen!?! The one that shows the elapsed call time and the End Call button... If I press the end call button, the screen goes away and everything is business as usual until the next time I get in the car and the phones connects to my unit again. Then the same thing happens. The supposed call that I'm having every time is with myself... the number shown on the screen and the Caller ID are mine...

I think this began happening after I updated my unit MCU to 2.65. It happens on stock ROM and Malaysk's ROM. Now I'm on MCU 2.71 and the stock ROM and still have the same issue...

Anybody having that problem?
