I also do not have this connector. Klyde does not include additional connectors, only partially. If the device is not installed in the car, you can at least try ringing the contacts with a measuring device. If you know how to use. Studying the photo, I determined that before the release of USB OTG, there really is a USB 2.0 HUB chip, and besides, I managed to get the original Klyde documentation, where this connector is indicated as OTG.

Can you tell the prossese pleas... i have same probelem
[Android Head-Units] Dr0idFanatic:
Same problem here. One solution I came up with is installing Nova launcher and hiding the top bar with tasker. It has its own app drawer and the icons show up there. Also the top bar swipes down.

In tasker you have to add:

PROFILES -> Nova Launcher, App/Services -> Immersive mode

TASKS -> Immersive Mode -> Hide both

If anyone knows another way please let us know...

I received today a new board with Android 9.0 + DSP. I enclose a photo.

Here I am attaching an old Android 8.1 board, without DSP.

I have already changed the boards, as I test, I will write what's new. About DSP it is clear, it is. It is important for me that the device’s sleep mode is also there! Not entirely clear with ZLink. In this program, a window for selecting the activation of modes has appeared. For example, wired CarPlay and wireless CarPlay, the same with Android Auto. Also, their various combinations. Before that, I didn’t have this in ZLink. I will contact the seller and clarify this issue. I will find something else to write here.
[Android Head-Units] sun.valeo:
I share my first impressions after replacing the motherboard with DSP. I'll start with the pros.

1) Sleep mode works.

2) DSP sound greatly improved.

On this, the advantages compared to the board without DSP ended.

Now about the cons that I discovered in a couple of days of use.

1) When you exit sleep mode, Wi-Fi is turned off. I explain, the device starts and Wi-Fi is disabled, it does not start from the curtain. You need to go to the advanced settings menu, then the Wi-Fi settings and enable the slider. What does this not always happen. As a rule, after a long sleep of the device. It was even once Wi-Fi was turned off after the device was fully loaded.

2) After exiting sleep, the device also exits slowly, you need to wait a few seconds, 3-4 seconds a dark screen, then the launcher starts and another 2-3 seconds, for example, a music player starts. Moreover, those programs that worked together with the player on 1/2 of the screen do not start. They hang in the background, but you need to display them yourself. It turns out that the device starts, as if in stages. Unfortunately, there is no effect that you would turn on the car’s ignition and everything would instantly work from the very place you turned off the car’s ignition.

3) I would like to notice the minuses of the DSP. Despite the fact that the DSP significantly improved the sound of its adjustment, it is very miserable and it will not be possible to properly configure the system with these DSPs. Those who are involved in car audio and are familiar with the DSP settings will understand what I'm writing about. I also noticed that with the advent of DSP there was some delay in turning on the sound when the player started. As if everything is lazy and starts with delays. Turn on the player, it starts as before quickly, but starts to play sound after 2-3 seconds.

In general, if you compare the old version of the motherboard without DSP and the new one with DSP, the latter is very slow and kind of lazy. Programs run with some kind of not natural thoughtfulness, which was absent in the old board. In Android 8.1, the launch of programs was faster and more stable.

I am attaching a screenshot showing the system firmware version and the MCU firmware version.

Information about the device KD-1280 / KD-12501.
[Android Head-Units] iNT0XiC8D:
I have been messing with this unit for about a week now and I'm not experiencing any of these issues.

I did try the hidden delay shutdown option and it drained my battery overnight so I switched that back. Otherwsie sleep after the ignition is off is working fine without battery issues.

The DSP in my unit is excellent. Far better than I expected and miles better than the Pioneer AVH-210EX it replaced. The high/low pass filters are nice for filtering out unwanted bass in my main speakers. At full volume with some test wav files there is no background noise, the volume gets very loud with little distortion in the upper range. I was planning to add an external amplifier with this unit but it's not necessary. EQ settings work well and I was able to create a very enjoyable sound stage.

The only wifi issue I have is the random mac address. I have an openwrt AP in my vehicle that the headunit connects to. It would be nice to fix this so I can use static addressing in dhcp for adb. The built in wifi chip seems to be limited in what freq and standards that are supported (ac/n/g). I had to use one of the other radios in my AP to create a simpler/slower network to connect to.

After starting the ignition the unit will take several seconds to show the boot logo, then android, then launcher. It continues where I left off and all the open tasks are still running in the background. If I was listing to Pandora or using navigation those continue a few seconds after showing the main gui screen.

Here are the shipped versions;
[Android Head-Units] iNT0XiC8D:
I stopped right before installing supersu.apk because it wasn't in the link provided. Inside the common folder is Superuser.apk instead. Is this step even needed? Running root explorer and other tools work fine and have root access. I'm able to open and edit several files in system directories and adb now has root. Thank you for your guide!

btw: You can change the boot logo without rooting using the 8861 menu. There you can pick any of the preloaded images or upload your own from usb.
[Android Head-Units] iNT0XiC8D:
Would it be possible to splice those into the obdii connector wires and skip using a BT dongle for obdii?

[Android Head-Units] Dr0idFanatic:
You can grant or deny root access to apps with the superuser app... I'm guessing the system is wide open root access without the app? Not sure, as I always installed the app. Just make sure you dont update the binary if you install it. Will bootloop.

Just one thing is not working...

If you activate the split screen, the immersive mode is deactivated and overlaps the current apps in split screen. :(

If you switch back to single view, it´s fine.

I didn´t find a solution yet, because I nearly always use the split screen to show navigation and Fcc launcher at the same time.
[Android Head-Units] wacko37:
Hey all and sorry to change the topic so drastically, but can anyone here confirm if the custom ROM's from "Hal9K" or "Malaysk" will work with our units? I'm aware that these ROM's are all specific to the "MTCB-D" MCU's but just wondering if anyone has tried them with the Klyde MCU

see here - https://xdaforums.com/showpost.php?p=82332247&postcount=1057

also here - https://xdaforums.com/showpost.php?p=74790877&postcount=363

from what I gather they are not MTCB-D MCU boards specifically (markings), but are probably identical boards all the same with different labelling etc?

Any thoughts?
[Android Head-Units] Dr0idFanatic:
The 2 links really dont show any info in regards to using a custom ROM. Also any custom ROM would have to support the resolution of the screen of the KD-1280 unit.
[Android Head-Units] sun.valeo:
I took Klyde from the seller, but I can't even say for sure whether I recommend buying a new board or not. With the replacement of the board, my radio tape recorder started having problems with the GPS. Very long cold start and unstable reception. Before that, this was not the case with the old board. :(

I was aware that it would be a long shot but hopefull none the less. I love this unit but dam does it need a decent custom ROM.

Out of curiosity has any manged to get voice dialling to work via google assist? Its not very safe trying to make calls while driving:eek: trying to manually scroll through your contact list.
[Android Head-Units] sun.valeo:
To use the Google Assistant, you need to completely remove the voice function and then activate the assistant in the Google settings of the device. Voice function blocks Google Assistant.
[Android Head-Units] wacko37:
Cheers for the speedy reply!

I'm guessing this will require root to remove the original voice function? Also can you confirm Google assist can complete the call via the Bluetooth app?
[Android Head-Units] sun.valeo:
You don't need root to remove the voice function. You can uninstall TXZ speech application in the usual way and then also delete the folder of this program from the device. The folder is located on the same drive as the Downloads folder. I would recommend that you save the TXZ speech folder for example on a flash card. You may want to return the voice function, and the key data is stored in the folder. Regarding the use of the Google Assistant in conjunction with a Bluetooth set, I can't tell you something definite. I met an application that performed this function, but it was for devices of the Microntek line, Android 8.0 I don’t know if it will work in our device. The Google Assistant itself will certainly work, since it has been replaced by a voice function in the device.

hi everyone, is there any way to get an obd2 bluetooth device working? When I search for my device, it cannot find it, nor any other device, it only finds the phone, I think it is limited by software. Thank you
[Android Head-Units] wacko37:
Cheers for all detailed info, I will get round to testing this out in the coming days, I will reply either way once tested.

It's so sad, :( as always these Chinese units have so much potential but yet are so unfinished in so many aspects.

My last unit was the 8" Newsmy Carplay unit, which lasted 5 year and is still going. The only reason it was so good truly was the strong XDA community that backed it, customs ROMs etc

XDA / android just doesn't seem to be what it used to these days
[Android Head-Units] wacko37:
Yes you can definitely add an obd2 bluetooth device, I can only go off my own experience when I added mine.

The 1st image is where you search for your device (please note if you have already connected your device it will no longer show up here and will only show up in the paired device tab 2nd image)

This app is not very intuitive and it took a couple of times to pair the device, from memory you have to tick the device and highlight it and then select the green link button. Sadly there is no clear indication that you have paired your device. But you can see in the top left corner beside the Bluetooth tab it says OBDConnected.

Hope this helps, also I can confirm Torque works also
[Android Head-Units] oski__dj:
I try to connect any device but it disconnects me ... I have also tried other bluetooth devices and I have not succeeded
[Android Head-Units] wacko37:

I would suggest contacting Klyde or who ever you bought the device from and explain your issue, as it may indeed be faulty

[Android Head-Units] rigattoni:
Not all OBD units are working together with most units.

On top:

You first need to check the PIN for the OBD unit. Should be 0000 or 1234. Depends on the OBD dongle.

The OBD needs to be the first BT device to be connected, so all other connections need to be removed from phones and head unit and reboot the devices.

If it does not connect properly, you should try another one. They are really cheap...

Connect your phone first, if the connection to the OBD is stable after reboot.
[Android Head-Units] oski__dj:
I think the problem is the bluetooth module or the top configuration of the module, what model of module do you have in the top configuration settings?

---------- Post added at 11:26 PM ---------- Previous post was at 11:20 PM ----------

Is there any way or application to know what BT module I have?

I have tried with AIDA64 but I have not succeeded
[Android Head-Units] rigattoni:
If you are able to do phone calls the setting is correct. There is nothing you can change, because otherwise you will loose the BT connection.

It´s really simple... If the unit refuses the connection to the OBD dongle, you most probably have an incompatible dongle.

My only working setting is "Suding Qualcomm 3008"
[Android Head-Units] oski__dj:
I have tried several devices and it does not work with any (only with my phone), I think that the problem is this, that in the preferences in my bluetooth address it says: null

[Android Head-Units] Dr0idFanatic:
Not sure. As far as I know it is for Android 8 not 9. You can try. It may just fail at some step or bootloop. I'd be prepared for the worst and have a USB with a recovery image on hand just in case it does. You can always restore it, but it will wipe all data if you do. Also you will might have to reinstall apps like zlink. Hope that helps.

I'm going to order a DSP upgrade board, if you're willing to wait for me to try. Will be a while though.

Android 9 DSP upgrade board.

Got my upgrade board a few days ago and installed it.

Wow. Clear and crisp sound now. I had no idea how much better it would sound with DSP. Amazing is all I can say. The 16 point equilizer that it comes with it works really well.

The system goes on standby and wakes up within 3-5 seconds now as well. No lag at all, its very responsive. Just as responsive as the old board with Android 8.

Overall I am extremely happy with it! Still have to root it and check all the functions. So far checked radio, bluetooth paired with phone, DSP settings, reverse camera, and steering wheel keys. All work as intended and no issues noticed so far. Definately an improvement over all.

Radio still does not pick up AM, but I think because my vehicle has a dual antenna and I just didn't hook something up properly. No problems picking up all the local FM stations.

Amazing and fantastic. DSP is definately worth it. Did mension the clear and crisp sound? Feels like sitting in a really good theatre and not a vehicle now...

Ill root and write more about it when I have time.

The pics below are: green board is the old Android 8. Blue board is the DSP + 9. Also the info for the new board.

When connecting a radio with a CanBus adapter, it is not possible to configure the steering wheel buttons. For the button settings to work, you need to connect the steering wheel buttons directly to the corresponding buttons of the radio. In this case, the steering wheel buttons must be resistive.
