[Question] Board Computer settings are missing

Hi,
has anyone experience with retaining GID/CID controls with RK3188 replaced original car stereo? More specifically I'm interested in Opel
Zafira GID. Currently GID controls can be accessed only from SETTINGS button on radio panel. BC menu can be accessed additionally from steering wheel buttons, but not Settings menu. If head unit has no implementation for accessing board computer settings menu, as it is done with Dynavin for example, then settings control will be lost.
Has anyone bump on this problem with RK3188 specific car head units?

did you configure factory settings and enable CAN-BUS?

Problem with steering wheel controls

Hi, I have a radio car gps for a toyota rav4, but I can not get the bluetooth steering wheel controls working. The steering wheel controls for + and - the volume work. Neither appears in the configuration of the controls of the steering wheel a button for the bluetooth. Does anyone have a similar radio?

Canbus steering wheel control buttons for media next/prev

Guys i have a MTCD Malaysk 8.0 (i think HA alhough i've crossflashed a few times so forgot exactly) and i have a raise canbus for my golf, how can i make my golf steering wheel buttons work in headunit, spotify etc, they work in the stock BT app, the keycodes according to MTCD tools is 300/299 but even when settings them to media_next/media_prev it doesn't work.

mtcd tools or rk3188 app from the play store.

I'm having the same problem, I can turn the volume up and down. My unit has android auto, it's really annoying I can't skip tracks with my steering wheel controls. I'm not sure what am I supposed to do with the apps someone commented above. Were you able to fix this?

Me too. I'm a premium member of Spotify but end up using my lame stock music because of this problem.

Dasaita Head Unit steering button issue

My car is a 2017 WRX STI with Harman kardon system. I know the dasaita is not designed to work with it but I've put my own amp, wired new speakers and made it work. I was having issue with turning on my amp and backup camera when I put my car in reverse. However I was able to map all my steering wheel buttons correctly. Then after that, I was able to figure out how to turn on my amp by moving one of the wiring pins in the harness and connect directly to my remote turn on lead to the amp. Also I was able to provide power to the backup cam when I put my car in reverse and now it works. My issue now is that my directional buttons on the steering wheel doesn't work anymore. Other buttons work like the mute button. Anyone have a wiring harness diagram for the steering wheel buttons from dasaita? I had an Android head unit before and that one I had no issue with it recognizing the steering wheel button commands.

With "directional buttons" you mean up/down (prev/next) right?
So, the Android units do not have too many choices. You either use the CanBus provided by Dasaita (or several 3rd party) for your vehicle "family" (usually same CanBus shared among different car models and brands) and you live with whatever is supported (usually only Vol +/-, Mute, Prev/Next), or you connect your steering wheel buttons to the "Key-1" and "Key-2" cables on the unit and you configure/program the unit to execute an action when buttons are pressed.
For using Key-1 and Key-2 cables:
1) You need to verify that your steering wheel buttons are restive (pressing a button changes the resistance seen by the unit)
2) You need the diagram of your steering wheel as different sections are connected to different units on the car and so use different cables. As an example, on my Mazda:
- Perv/Next, Vol +/-, Mute are one resistance bridge that goes to the stereo (one cable, as the "-" is always chassis)
- Talk, Pick-up, Hang-down is another cable that goes to the Bluetooth unit (again one cable, and the bluetooth unit then connects to the Aux of the stereo)
- Up/Down/Left/Right and Enter (the other side of the steering wheel) goes to the Computer Display (have not played with this one, no idea if it is one cable or more)
In my case I left the Vol/Mute/Prev-Next alone as it was working via the CanBus, but I cut the cable going from the steering wheel to the Bluetooth Unit and connected it to Key2 in a PX5 MTC-D Dasaita unit and configured those keys to handle phone calls + Google Assistant. I guess I still have Key-1 if one day I want to completely kill the factory "computer display" that any way only shows basic statistics.
Hope this helps. I can share the Mazda Steering Wheel circuit so you can see what you should be looking for (most probably Subaru will use other color code for the cabling)

Key 1 Key 2
I bought some external buttons that I want to connect Android car stereo dasaita can you indicate the cables key 1 key 2 where to connect?

Dasaita PX6 for Mazda CX7 trip computer and clock settings

Hello all
I have searched a lot and couldn't find any relevant information anywhere.
What I wanted was to be able to use the clock and trip computer in my car
(a 2008 Mazda CX7 with Bose audio). When the stock head unit is replaced
you lose the Info and Clock keys so you cannot adjust the time or change
between the various trip computer info.
So by playing around I discovered that you still can perform these actions
by using the steering wheel controls. In specific, if you press the MODE button
for 2-3 sec you enter the settings mode. There by pressing the UP arrow
you emulate the INFO key and by pressing the DOWN arrow you emulate
the CLOCK key. With the above information you can use the clock/trip
computer as before
The above might have application on other Mazda vehicles too that
use the canbus adapter to keep the steering wheel controls. Wouldn't
hurt to try anyway!
Now if only I could find a solution for the fader/balance problem of
the rear speakers (by utilizing the canbus adapter provided) I would be happy!
I made a small video showing the above for anyone that is interested.
