Did you follow the link, is it a similar connector? Three wires to me sounds like sw1, sw2, and ground. Which is equal

to a resistor type and what your HU can handle.

Surprised searching through the forum that Overalys app is not being used by more folks. It really works well for a HU situtation. I have some torque widgets and a music player widget set to float when I open my GPS app (Waze). So I get all information in the navigation screen.

[MENTION=3744488]devilsoft[/MENTION] - love your PCV Builder app. But after installing it, my Overalys are no longer loading up on startup. Also mtc-keys Xposed module has become very hit or miss. Don't wanna bother you with request to add it if not a lot of folks are using it. Is there a manual way to add an app startup to PCV builder?

[MENTION=3744488]devilsoft[/MENTION] - Also, if I do need to unistall the PCV builder app...do I need to do anythiing extra (like delete files created by the app)...or it just a matter of simply unistalling. THANKS.
[MTCB Android Head Units Q&A] :
According to Terminal Screenshot. The Mount Point for External SD is not binded. Please provide your Setting inside PCV App. I recommend to remove all which is related to tomtom, all folders you can find. Then restart with the procedure which is listed. If the directory on internal SD is exisiting already, it wont work. I have to try several times to understand the procedures but i am completely new to android :).

So: Remove -realy- all tomtom related files. Internal and External. I used SD Maid, to find useless data (this function is free).

edit install-recovery.sh via PCV app, as mentioned in manual you got provided.

You will win this "battle" :)

root 4.4.4 device using *#hct#root# - Not Working

Hello all,

Ive have a unit with 4.4.4 (stock FW) and ive tried to do the *#hct#root# trick to get root.

so i did the following:

1) go to settings->Factory Settings-> enter *#hct#root# -> got "ADBROOT ON"

2) reboot device

3) open settings->searching for #SUPERUSER under "Facotry Settings" but nothing appear.

4) tried to use command ADBON as previously stated, but no luck.

5) installed "SuperSU" / "SuperUser" but with no luck, after running it it says binaries cant be installed.

6) installed "root explorer" to check if i can enter /system directory (is it enough? how can i know when its rooted?)

ive search the thread back and forth but it just repeated as i did.

can someone please let me know if i doing something wrong?

appreciate any help :fingers-crossed:

The Builder App is not interferring with any other app really.

Before using builder app, you had a custom install-recovery.sh? What apps did you choosed to run on startup? There are known apps (like torque) which generates problems in HU.

Just simply uninstall the app. No need to delete other files.

P.S.

I can add the Overlays to the app, but which one you need? There are two versions: Overlays Pro and Overlays - Float Everywhere.

Thanks. I chose Torque and Poweramp at startup. I did not have any custom install-recovery.sh before using your app. The app is doing its function fine - both start up fine. But as you say, Torque could be causing the problem.

I am using the Overlays - Float Everywhere (i.e the free version) from the Play Store. Would be awesome if it can be added to your app.

Hello all some help would be appreciated. I'm having 3 issues with my kgl 2.72 and malaysk latest rom.

1. The unit connects to my one+2 hotspot though there is no actual data connection.

2. Cannot sync contacts although Bluetooth works fine.

3. And most irritating. When I install any malaysk rom lately I cannot get a GPS fix. Let me explain. When I installed it I checked and the fix was there however after a few days (reboots) I'm loosing GPS fix and can't use any navigation software.

Any help on the above would be appreciated.

I have some questions.

1. I mean that i read it here, but I'm not sure. At the moment I have very often the bug, that the volume button not works. Mute works, but louder and quieter not. I don't know when it doesn't work, but after a while no function.

2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?

3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction. After a minuten the radio shows the bootlogo and have a loop. So i have start the radio new with reset or power off from the car.

All this errors are since a few days. I tried to do any settings but the problem is always here. Does anyone no about that? I think it's an app, but I don't know which one. The last chance (if I get no solutions) is to install another rom?

I have JY 2.73 with the Malaysk Rom from September (1024).

I have this too. I determined that this is related to apps which don´t use MCU Sound output. Problem appears when Navigation system want to "talk" and you change the volume in this moment, or a background app want to tell something too. In that case, the volume buttons immediately gone away until the unit reboots. I had this problem much stronger with power amp. Power amp has its own equalizer and ignores gps and eq settings from the device (like mixing). I reduced the apps and i got the problem not longer. You may use no MCU controlled apps like media player, radio, etc, so this behavior can´t appear. Maybe a MCU.img update would help if available.

2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?

Same here, shortly deactivate the wifi and reactivate it. Disable "Optimize Wifi" in wifi Settings. It seems that the power saving function wants to save too much power. Module turns to 10% power consumption and so the signal goes lost. (Firmware error)

3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction.

[MTCB Android Head Units Q&A] stresu:
Hi all,

I guess this is my first reply in these forums, though I follow topics I'm interested in.

I was wondering if anyone could help me with an advice on what could be the problem with my unit.

I have a Klyde unit for Mazda 3 2008. It is the 4x Core and HD screen one. The problem seems to be with the Canbus decoder I got. Thing is the buttons on the steering wheel work well, also, I can adjust the car's clock using the interface provided with the unit (Control Settings I think is the name of the app) but I cannot access the Trip Computer no matter what.

Previously I had Eonon D5151 (WinCE one) and it worked to access the Trip Computer using the steering wheel buttons, but with this one...no chance.

What I tried without success:

- changed the Canbus selection in the Factory Settings (not all of them, just the ones containing MAZDA in their title)

- click all the buttons on the same interface used to access the car's internal clock

[YOUTUBE]watch?v=9eS3YPfGJ6g[/YOUTUBE]

- tried to remap the SWC buttons but this action doesn't seem to work either (not sure why I did this, though, cause it would make no difference, haha)

[YOUTUBE]watch?v=TRWkI1EZ6LA[/YOUTUBE]

The Canbus decoder I got is

MAZDA-RZ-01, HW: V3.4

Since I can access Clock functions on my vehicle I was thinking the Canbus decoder is the correct one. Or ... is it? Should I ask for a different Canbus decoder? (anyone with Mazda 3 BK has a model of decoder that works and can tell me the SN?)

Few more secondary questions:

- my Up/Down arrow keys on the steering wheel change the songs in the opposite direction (Up changes to next while Down changes to previous). Since I can't reconfigure my keys from the HU, is there any other way of doing this? (except getting used to it, of course :D)

- there is a Beep sound when clicking the screen etc, which I would like to have. But the "stock" one is very very very loud and this version of Android doesn't seem to have Volume adjustment for it. Is there any way to solve it?

Thanks!

Thanks for answer. Soooo:

1. I had isntalled PowerAmp but I removed it. But how can I not use MCU Apps... I need the radio... navigaton app is Waze.. and Music yes is the music player from the radio... Should i use PowerAmp?

2. I know. Optimize Wifi is disabled. But it doens't work. It always works, but since a few days I have all the problems.

3. Hmm :/

And yes.. I have one more problem: If I turn off the key from the car I set that the radio shut down after 30 minutes. Normally the radio are "black" and the board comuter shut down after a few seconds. Since a few days (i said all the problem comes on one moment) the ligth into the DVD-tray is on and the board computer are not shut down... I think it's another problem.. the MCU I think is the error with volume and the other problems I don't have 1 week ago... it comes if i do anything in the settings. But I have to tried to find the problems - but nothing. I have installed 2.73. Should I try previous version? :/
[MTCB Android Head Units Q&A] Tha_Stig:
To your up/down arrow keys issue. Go into the factory settings (password: 126) and on the other tab there is an option to switch the arrows on steering wheels. make sure this is clicked/unclicked for your car, these settings are for both LHD and RHD cars so some finetuning is needed. Also, remember that the check box for each option is on the left side, click the actual words to be safe.

Thank thanks a lot for your support and patience.... It's working very well!
[MTCB Android Head Units Q&A] tmiller101:
Electronically, they should be the same point. On my Harness the thicker ground goes to the HU and the smaller wire feeds ground to the CANbus decoder. The same with the hot side. The larger line provides power to the unit and the smaller to the CANbus decoder.

Might even try just grounding the HU chasis. Run a cable from the vehicle chasis to the HU chasis.

If you are hearing a slight static on the speakers you have a voltage potential problem somewhere. And an additional good strong ground never hurts.
[MTCB Android Head Units Q&A] superbass311:
Would the easiest way to test this is just run a wire from the 2 grounds to the ground on my battery and test. That way I don't have to drill another ground if it is still happening?

Sent from my Ascend Mate 2
[MTCB Android Head Units Q&A] :
You are welcome :)
[MTCB Android Head Units Q&A] tmiller101:
Short answer: Yes.

Long Answer: You shouldn't have to drill any holes. You don't need to make a run back to the battery. Matter of fact the shorter the run the better. Find any screw in your car that touches the metal chassis (i.e. ground) and run a wire from it to any screw on the outside HU or to the black cables. (Electrically they should, should be all the same).

I had a hell of a time finding a ground scew in the cabin of my VW Jetta. Everything is plastic, fiberglass, and other types of nonconducting material. If you have a volt meter place one lead on a hot wire and take the other lead and start touching screws until you see 12v. If you read anything over 12 volts you probably have a good grounding point. If its under 12v find another screw.

You can also check the ground by setting the volt meter to Ohms and check the reading from the negative terminal of the battery and your grounding point. Anything under 10 Ohms is good, above 10 and you are in a grey area. Above 100 Ohms, bad ground.

Hey guys,

so I tried now to remap my hardware keys of the unit.

I want to change my radio button to Spotify. So I've got car service and the correct pkg name for Spotify (com. spotify.music) and know which button it is in my case (app_43). Car Service is also enabled in Xposed.

I created the "mtc-keys" folder in all mentioned paths (mnt/internal_sd mnt/internal_storage mnt/external_sd) and created a "mtc-keys.ini" file in there. But the button is still mapped with its original function.

Any ideas what I could try next?

Can you remap the other buttons? It took some trial and error for mine to work. I moved the ini file to every SD location before I found the correct location. Also the case and wording of the ini commands make a huge difference. And always reboot the system between changes.

Update: On the way home I quickly remapped the radio button to iHeart Radio and it worked. So the radio button can remapped.

Have you checked the lines going to the Amp. Make sure the amp is still working. Is the Amp not turning on because its not getting the correct turn on signal or is it bad? Maybe bad fuse.
[MTCB Android Head Units Q&A] martijnb23:
it is possible that it may be due to the radio, because it has always worked.

otherwise I'll go check the wires and fuse
