Thanks for answering, I see that you also speak (Spanish)

I have tried as you say:

-Unlinked all devices.

-Turn off any bluetooth device around the car.

-Press Search for Devices in Dasaita and Press OBDLinkMX+ button for 1s, simultaneously.

-When I see my OBDLinkMX+ in the list I press Pairing.

It doesn't work, I try to do it from Settings / Bluetooth

It doesn't work, using the Bluetooth App.

Thanks.
[MTCD Android Head Units General] marchnz:
Has your OBDLink ever paired successfully on your unit? If it has, read on, if not search the forums to understand the limitations.

My experience is on Hal Android 8 ROM which has modifications to allow OBD BT other than the rubbish reseller elm knock offs.

Have you tried deleting all BT devices, factory resetting your MX, and making sure all other BT devices are turned off when pairing?

I have an OBDLink LX which can be problematic when re-pairing, say if I have removed it to use in another car.

It always appears in the list, but doesn't want to add. Only after deletes, resets and restarts does it re-add.
[MTCD Android Head Units General] XaviRM:
I tried deleting all BT devices.

I make sure of other BT devices are turned off when try pairing.

But I have not tried factory resetting my MX+ (I hope this solves the problem, I run out of options.)

Thanks my friend.

[MTCD Android Head Units General] marchnz:
Has it ever worked? Yes, no?
[MTCD Android Head Units General] XaviRM:
Never, No

I factory reset my MX+ and it made no difference.

It connects perfectly with any of my IOS devices, iPhones and iPads.

I don't have any other Android device to test the connection.

My MX+ has 15 days of purchase and my Dasaita 22 days.

Any other suggestions?

Any modifications at the root level to try to connect it?
[MTCD Android Head Units General] Guillermo h:
I insist, the same thing happened to me and I even thought of returning the OBDlink MX+, try again the steps that I indicate; the first time you do not try to connect to the application installed on the unit but in the app of your I phone, you must try several times if necessary and it is likely that once you manage to establish a match continue the problems where a window tells you that it is not possible to connect to the vehicle, you must continue trying.

Carplay issues looking for solutions dasaita mx6 rav4

Hello I installed the newest sygav unit in my car which i think is the same as the dasaita unit and i just anted to know if anyone else had these issues and or might have solutions i'm currently on the android 10 firmware

-There is static coming out of what seems to be my right dash tweeter

-After an update i feel like my wireless carplay connection is a little slower than before and just overall just a little more laggy than previously (animations don't seem as smooth)

- my rear speakers simply just do not work anymore after installing the headunit which doesn't make sense to me because from what i know in my XLE RAV4 the audio is just one connector for all the speakers since i don't have the JBL upgrade with an AMP

Hello people. Does anyone use the Foobar2000 app for listening to music?

I own the PX6 unit and when I listen to radio or music with the integrated

music app everything is fine. When I use Foobar to listen to music then

if I try to open the radio or stock music app, they immediatelly close as if crashed.

To solve the problem I need to open Spotify, start a random song and then I

can use again the music or radio app.

I currently use Android 10 but I had the same problem with Android 9 and also with

Hal's rom. This is only with the Foobar application.

Does anyone have the same problem? Do you have any idea what could be the problem?
[MTCD Android Head Units General] Bytec:
Yes, I have the same problem.

Looks like Foobar2000 has some problem releaseing audio resources. I have no other solution other than what you already said. I've stoped using Foobar2000 for time being. Using BlackPlayer for now.

HI all. Been following along here. Running a PX6 with HCT4_RK3399_9.0(20191218). Just looking to find out is this still the latest version for this model? Has anyone upgraded their PX6 to Android 10? If so, how? And is it worthwhile? Thanks!
[MTCD Android Head Units General] The Android Attorney:
The latest one is HCT2_RK3399_10.0_ota(20200808).zip

[MTCD Android Head Units General] digitron80:
Probably its because you were on Android 9. OTA updates of android 10 won't work when we

Hi everyone

I have a V940 PX5 HA and I upgraded with last released 2020042, but i have a big issue with Google play, It does't upgrade and log in on my profile (remail stuck in a "checking" page while every other app can use the internet connection). So i wont try downgrade to the previous version HA_px5_9.0_ota(20190731) to try to see if work better but during the installation tells me that it can't downgrade to a older version.

there is a way to do this?

thank you

I have a usbA to usbA cable, so I did the first method from this post:

You will also need an IMG file with Android 10. I got mine from https://yadi.sk/d/umCvHqCDzHccr?w=1

from folder RockChip PX6 Android 10\HCT file HTC7_RK3399_10.0_IMG(20200415).zip

Then you can apply whatever OTA update of Android 10 you want (HCT or HA or CHS)

Nope, not an MTCD/E/P and definately not a Hot Audio device..

Your MCU prefix is not one of these therefore your unit is some other weird and wonderful Chinese junk concoction and the MTCx forums are not applicable.

Haven’t really noticed that many changes, except for one thing which is nice: auto-scanning of FM radio stations is working again in the latest update. :)
[MTCD Android Head Units General] tnegun:
Is that the Auto Frequency switch for FM you're referring to? I installed it on my Max6 and noticed that the volume with an amp has increased even with everything plus 20db in factory settings the volume had to be 20 or so to be heard when driving and then couldn't be turned up very loud now its around 10. It did introduce a Pop from the speakers/amp when powering off though which wasn't there before or at least not as loud.

I ran into an issue after upgrading from android 9 to 10 on a dasaita px5 unit where the screen would be distorted/fuzzy for 5 to 10 minutes after every boot. In case anyone else runs into the same issue, it seems to have been specific to HA3_px5_10.0_ota(20200706) or the combination of that ota and the 9" display that came with my unit. Reverting to HA3_px5_10.0_ota(20200610) fixed it for me.

Hello All

I have dasaita max6 px6 with mcu 3.56 on hal9k rom android pie and BT profile is on WQ_BC6

I have installed the external mic while ago and still voice is better than internal but i have to almost shout so others can hear me well

I read through forums and saw that in px5 the mic connection was parallel and people had tp unsolder the internal mic so the external can work

While others soldered external to the internal mic wiirng while others put only an extension in tbe external which resulted in making the internal very good by itself

Now I believe that the case is different in PX6 as I think the unit is really using the external one because when my mouth is coming nearer to the external.mic then other end says he can her me better and so on

Now my main question, is there any workaround to raise the external mic gain ?

Is there another BT profile in factory settings that anyone tried and it is better ?

Is there another MCU version that is better in this aspect either older or newer ?

Sorry for long speech and thx in advance

I had similar issue once. Dasaita support suggested to do the following and it worked for me (for MCU v3.62):

Settings - car - factory settings - password：hcttest252

Click to confirm, power off, then power on​

It should be a full power off - not a standby.

another option: reprogram mcu image (dasaita suggested v3.62) with dmcu.ext containing screen:18 and then follow the steps above (all tested on px6 1280x720 only)

there is a sense to say that dasaita support is very responsive

Might have the solution for you as I had this same issue after having received an incorrect update for my Max10 unit.

Go to settings, then car settings, factory reset then insert the following code: hcttest252 and reboot your system

There are 3 codes I am aware of:

hcttest256 - lowered resolution 1024 x 720 (Max 6 version)

hcttest253 - monochrome mode (like in your situation)

hcttest252 - high res mode 1280 x 720 (Max 10 version)
