My problem is that when my factory radio is removed, the Odometer screen goes with it. My car ECU keeps track of its own miles but does not have a screen to show them. If I re-install my factory radio it will display the correct mileage.

Now when I installed my HU I was left without a screen to shows my miles. So now I need an app that can count my miles through GPS, run on boot, and stay on while I'm driving.

If car has no option to show odometer, it must be stolen. Lol. Why can't u just tell us the car make and model? Hmmmm...
[MTCB Android Head Units Q&A] Franky692:
I can add these info for Subaru SWC:

Wires connected to the car's Steering Wheel Audio Controls (SWCs).

In Subarus, all SWC wires go directly between the HU and the wheel. Neither side connects to ground or a voltage in the car. Inside the wheel, the buttons connect to a network of resistors. The HU sees a different resistance for each button (and a higher value when no button is pressed).

Many HUs today can work with OEM SWCs. However, most HUs require a separate interface module (to convert from the Subaru's resistors to what the HU expects to see). See additional tips in my 20-pin HU installation guide.

Most Chinese-brand HUs (e.g., Caska, Eonon, Flyaudio, Rosen, etc.), and those without any brand can be connected directly to the SWC wires in cars with resistive SWC buttons. These HUs have the equivalent function of a steering wheel interface module built-in, and have on-screen menus to "learn" a car's SWCs. Connect as follows:

•My BROWN/BLACK to the other BLACK ground wires (on my 20-pin harness and HU's harness). If the HU's harness has a secondary black/ground to use with the SWCs, just connect that to my BROWN/BLACK (you don't need to tie those to the other grounds).

•My BROWN/RED (Subaru pin #4) to HU's SWC input #1 (often labeled "KEY1", "A/D 1", or similar).

•My BROWN/BLUE (Subaru pin #13, or pin #11 in some Legacy/Outback models) to HU's SWC input #2 (likely "KEY2", "A/D 2", or similar).

Find on-screen menus where you program the HU to assign a function to each of your car's SWC buttons.

Has somebody experienced a way to get SWC working with the HU and in case how (settings and wire connections)

Thanks

[MTCB Android Head Units Q&A] Franky692:
Thanks for your reply.

I know, as I wrote my Subary Legacy has resistor type SWC. I don't know if the setting in factory settings in CANBUS is related only to canbus cars or also to resistor Keys cars.

I tried with CANBUS set to "no" but without luck.

The two wires Key1 +5V and Key2 +5V from HU are connected to pin 4 and 13 of Subaru harness Steering Wheel Controls (SWC1+) Steering Wheel Controls (SWC2+) but are not working.

So first question is in a car with Resistor SWC the CANBUS setting in factory setting has nothing to do?

Are my wires correctly connected?

Since with my previous S150 they work ok I suppose something wrong is in the settings or wires....
[MTCB Android Head Units Q&A] ktibor69:
Doesn't the Steering wheel key setting app work?
[MTCB Android Head Units Q&A] Franky692:
The problem is that in the key setting store app, when I try to store a value for a swc key nothing happens, I guess because the AD converter can not recognize a Voltage changes when I press the SWC key.

In Subaru there is a resistor network that change resistence value pressing the swc key.

Tata, please I understand that your Ford has resistor network similar to mine.... So since in my HU there is no CANBUS MODULE the factory setting canbus type has no influence on SWC commands. Is that true? I have to set CANBUS type on "None"?
[MTCB Android Head Units Q&A] ktibor69:
It's not necessary, I set the Mondeo Canbus type in the factory setting, because my rear camera is controlled via canbus and near the SWC app works .

My idea is, that check the resistance changing on the pin 4 and 13 of Subaru with a multimeter.
[MTCB Android Head Units Q&A] Franky692:
But only to understand, if you set NONE on your canbus type setting the SWC control keys work the same? If Yes the CANBUS setting has nothing to do with SWC resistive type....

Thank you for your reply.
[MTCB Android Head Units Q&A] ktibor69:
" if you set NONE on your canbus type setting the SWC control keys work the same?" Yes., if you connect good the Key2 or Key1 cable to the SWC of your Car.

Do you connect the cable of the car's SWC directly to the Key2 or Key1 cable, like on my photos?

Tomtom and PCV problems

Hi everybody, I have a EONON 4.4.4 RK3188 head unit.

I installed the last Malaysk's Rom and I am facing some problems about Tomtom installation and PCV settings.

1- If I install my TomTom Europe through the GPS Card, that won't start and gives me some "connection problem"; instead, if I install it in SD Card it starts but then it crashes after 1 second.

2- About PCV settings: when I enter in to the app and I try to swipe on the settings (e.g. Tomtom fix), I realize that when I enter again the settings are again off. Why does it happen??

Thx

Bluetooth calling

How does your Bluetooth app work?

When I make the call ( I push the BT sign) the radio app or Poweramp will be killed. After the calling I have only silence.

How can I set the bluetooth app, that the calling only make pause the radio app or Poweramp, and after resume these app. Like the receiving calling.
[MTCB Android Head Units Q&A] Franky692:
Thank you

Ok, so my first useful info is that I can set CanBus setting in factory setting to "none".

Second. The Cable between Subaru Harness and HU Harness is provided with the HU. I see that Key 1 5v from HU goes to pin 4 of the this link and pin Kye 2 5v from HU goes to pin 13 of the previous link. I have to check the Common - connection is correctly connected, but is is that the case the SWC should work.

Hope to find the problem soon.

Thanks for your help! I installed MTCB-KGL-V2.72 and changed the keys in Factory Settings. Everything works on the bench, still not installed in my car... waiting for a CAN-Bus and harness that wasn't in the original shipment.

I have a question though.. I would like to install a MCU with the updated music and sleep settings. Does it make a difference and also is it now part of the new ROMs?
[MTCB Android Head Units Q&A] agentdr8:
If you're on a Malaysk rom, it comes with the Xposed Framework preinstalled. You would go into Xposed Installer->Framework, and enable the app_process. Then reboot. When it comes back up, return to the Xposed Installer->Modules, put a check next to XposedMTC, and then open the module preferences by selecting that entry. Under App/Modeswitch Settings, set your preferred music and video players (Poweramp, JetAudio, etc). Reboot again.

When it comes back up, open up the app drawer and find the MyMusic and MyRadio launchers. Use them instead of Radio and the default launcher for whatever music app you were using.

Files received. I'm currently out of town on business travel, so I won't be able to look into anything until next week at the earliest.

Could someone post some detailed instructions on how to extend the wifi antenna? My dad is going to be here this weekend and he's got a lot better dexterity than I have.

My car is not stolen.. I drive a 1997 Limited Edition Toyota Supra. It's rare and very hard to find and I'm 99.99% sure that I'm the only supra with a android HU.

All I need is an app that can count my miles by GPS and run boot with the android system and not turn off when driving for long periods of time. Pretty simple right?

I have no clue what so ever, I have just 5-6 apps installed and I haven't installed anything new for weeks, even months.

The unit keeps the time and date...

Any thoughts?

is there a way to determine if a certain app from the stock does this? I have the Basic KYD ROM that has root and 3Gb partition.

At the end I fixed 50% of the problem but can be enough. The SWC2 Key 2 was connected to a wrong Pin on my CAR Harness. Changing the position to the right pin now SWC 2 with Key 2 is working. SWC1 Key 1 is still not working. I switched SWC 1 with SWC 2 pins and now Key 2 connected to SWC1 is working, but SWC2 connected to Key 1 is not working, so I guess for some strange reason Key 1 of the HU is not working. Now I have the volume, seek/next track and mode connected to Key 2 OK, but the 3 Phone commands not working. Is not a big problem, for me it's enough to have the more used command working.... I can investigate a bit more about the fact that KEY 1 is not working, but is not so important at this point.
