Subwoofer control after upgrading MCU. - MTCB Android Head Units Q&A

Hello,
My headunit had MCU GS 2.78 what was giving me a bug,somethimes when starting the unit fm radio started at load noise and I had to restart.
After updating the MCU the bug was gone but I noticed that I had no control of the subwoofer,looks like it is controled by other bass controls but sliding sub control does nothing.
Downgrading back to MCU GS 2.78 give me back sub control.
I tried diverent MCU and now i,m on MCU GS 3.07.
Anybody knows why the sub control is not working above 2.78???
Or do I need special MCU because of build in DSP?

Hello Diablo-2u,
GS 2.84.1 will fix your issues and retain the sub woofer controls. I had the same issues with my unit in the beginning.
Cheers

Hello, I cannot control my subwoofer level in the equalizer app. I have a mtce lm v3.43 unit with integrated dedicated DSP (ADAU1401).
I already upgraded to hal9k V4 with the new DSP EQ app but even there I don't have the possibility to control or even mute my subwoofer channel.
Any experiences on that?
Thanks guys

I have Isudar H53 it also has built in DSP. Only the filter can be adjusted on the sub out. The SubgainL and SubgainR not works, the output signal smaller than the 4chs. The output voltage and volume value is strange.
volume 0 > sub output 0V
volume 1 > sub output 300mV
increased the volume to 17 the sub output is till 300mV
Volume over 18 the sub out voltage begin to increase.

Audio Issue with Dasaita 10.2" Android 6.0 unit - Mitsubishi Lancer Evolution

Hello, I recently installed the above Android unit into my 2014 Mitsubishi EVO with Rockford system. It came with the can bus decoder MT-SS-03 for 2014 Outlander. I set everything up in the factory settings menu but I'm having a major audio problem that sadly is ruining an otherwise awesome experience.
If I listen to any music at high volume all system audio cuts out completely for 5-10 seconds at a time. I've found this problem is directly related to the volume. The louder it is, the quicker the audio will cut out. I've double and triple checked all wiring and pins, updated to the latest MCU 2.59, Android system (8-3-2017), etc.
I'm out of ideas on what to try next but hoping someone here can shine some light on the situation. Thanks in advance and looking forward to putting an end to this issue!

HELLLP - Dasaita said I can’t use an aftermarket amp??

Hi everyone - a little desperate here. I have a Dasaita 10.2" Android 8.0, Octa Core 4GB+32GB in my Jeep Wrangler. Amazing unit overall but the amplifier app doesn’t seem to give me any EQ, Balance/Fade or Subwoofer control. If I move the sliders around nothing happens to the sound. I reached out to Dasaita and the response was that I cannot use an aftermarket amp with this unit - doesn’t that seem absurd? I would think the RCA outputs could output to any amp. Really hoping someone has has experience with this... thanks!!

I installed mine and am running into the same issue. Does anyone have a solution? No RCA outputs that I can see. I am thinking about returning it.

My RCA outputs work fine though as previously pointed out the Fader and EQ controls seem to have no effect. You can use a music player like PowerAmp which has its own EQ controls to get around it... I've reached out to Dasaita to see what's going on...
I have a similar unit from dasaita, nissan murano.
I am using RCA to my amp, and the built in equalizer and loudness work fine.
The only issue is I am hearing a small static noise when no music is playing.
Change canbus settings
I just installed the v840 7in version in my jk last week on 8/5/18. First thing I did was check how itsounds. Went to the EQ and did not work no setting made any sound change and the fader did not work. My heart fell out and I was ready to send it back.
I went ahead and updated the system files to the most recent but did not change anything with the eq or fader. I then recalled discussion on Jeep forum to change the canbus settings. When I went in the settings it was Jeep 46 I changed it to Jeep 78 and voila EQ works and also the fader although the fade is reversed which I already knew was an issue. Only difference is I don't have an amplifier so I cannot verify that issue although others have amps working fine with full eq functionality.
RESOLVED: Dasaita fader/EQ control w/ external amps
More from jeep forum
For those reporting issues with built in EQ and fader controls on Dasaita PX5 Octacore units not working with aftermarket amplification I figured out the settings....

Open up system settings and navigate to "CAR" and then "Factory Settings"

Enter the Password '126' to get you into the Factory menu. Navigate to the "CanBus" tab:

Change the selection under Amplifier from "With amplifier" to "Without amplifier", click [APPLY] followed by [EXIT] and let the system reboot.
RESOLVED: Dasaita fader/EQ control w/ external amps
Use the jeep 46 setting to access the amp option

Thanks for the info, It works for me, but the bigger problem is, the factory alpine amp don't seems to work, no bass at all.
I have checked every jk forum i can find but no solution. ppl mentioned Pac canbus a lot. but I prefer the unit work it self out.

I dont have a jeep, but there is a similar issue with the tundras, if they were using the stock amp they needed to have a CANbus decoder to utilize the factory amp some units have them already installed some don't.

Thanks, guess I will have to cut off the garbage they provided and rewire the harness.
I got this Disaita for a 2014 Jeep Wrangler JKU with the factory alpine sub/amp. The sound works great. It's true you can't control the fade/balance of it because the jeep's computer is controlling it. I know the OP has an aftermarket one, but that could be what Disaita thinks you are talking about. The included canbus, wiring harness, etc all worked out of the box.

2012 FJ Cruiser install here. Same issue. I changed the factory canbus settings, but don’t understand the options. I am getting rear sub output but no fade control at all. I don’t know enough to retire it all, nor do I have the time or patience.

Disabled Canbus app to avoid issue? Potential problems?

Hi
I've purchased a PX5 MTCD based Dasaita 10.2" unit for my Peugeot 208 2016 to get Android auto.
Quite pleased with the design and features overall but had a show stopper when I realised that even if I set the unit to mph in the control settings app the car would flip back over to kph on my speedometer when it started up. This was even though the setting stayed as mph in the control settings app. Indeed I'd have to flip back to khp then back again to mph to rectify.
I tried first of all upgrading to the latest version of my DCU software (2.99MTCE) and updated and tried different ROM's to no avail.
Anyway. I've found a sort of workaround I think which is to disable the canbus app in Android settings. This has stopped the speedo from updating and the steering wheel controls still work. Have I broken anything else though? Does anyone know what force stopping this app does?
Thanks
Dasaita provided me with the fix today. If you PM me, I will send you the file and instructions. Note that you do the update at your own risk.
Fix= new firmware? Android or MCU?
Fix is an update for the canbus. It's not an android firmware nor MCU update.
Hi @jamesbruton, how/where do I turn off the Canbus app?

Steering wheel control issue

Hello
I am having problem with controlling the steering wheel control to next/pervious the song.
The radio and the music of the rom is working fine but when using other apps like Spotify, YouTube playlist... Etc is not working I have to do it on screen. Is there anything I can do in settings?
Btw Iam using 4.4.4 malaysk rom rk3066.
Hello! Were you able to fix the problem? I have a similar issue with my car, when I go to Spotify and start playing a song, I can go to the prev/next track but as soon as I leave the app, I can no longer go to the prev/next track. I can do it from the notification but not from the steering wheel or the controls on the face of the headunit. Also, whenever I try to skip a song from any of the buttons, I also lose control of the volume. So, I'd love to know how you fixed it if you have fixed it.

Being an mtcb, since posted in mtcb forum, suggest time to buy a newer unit to update your old mtcb unit, such as a FYT based unit uis7862

I see. Upon further testing my problem seems to be android related. I can't skip songs if I don't have the app open on screen. Had this with one of my previous phones too and it fixed itself one day. We shall see.
