[MTCB Android Head Units Q&A] herdy33:
Thank you for your attention..

The problem is, even though the engine is not cranking, only the ACC or ON, the engine is on or off state, when the head unit is turned off from the normal state, then turn it back on, that's where the problem arises.. so without the engine in cranking, a problem that will remain there.

Head unit seems not to reboot, as only a temporary sleep.

Does the diagram it can solve the problem?

You're saying the headunit goes to shutdown when you turn the key to ACC from LOCK/OFF?

Can anyone recommend a OBD ELM327 USB cable that works with the Klyde head units? I ordered this one on Amazon, but it doesn't work...at least in 4.4.2 or 4.4.4. I've got a Bluetooth module that works (at least in 4.2.2/4.4.4), but I'd like to use USB.

[MTCB Android Head Units Q&A] jugi:
couple questions

Hello! Tried this with 800x480 unit with 4.2.2 android, looks good but.

Works well, two qestions:

-RDS TEXT (Channel name) is too bix, overlaps slightly the upper bar.

-Mhz could be even smaller to compensate text.

-When I use my SW buttons < > it will correctly switch to the next channel, but it is impossible to jump over the FM1-FM2-FM3 regions.

-This is strange as when i hit search it will loop all FM regions and store channels as you expect.

-Correct function would be to jump start to next FM region when < is pressed.

For example, Merceds Benz has ultra simple radio, could this layout work with here also?

(still no links allowed)

Best, Jukka
[MTCB Android Head Units Q&A] pencilhead:
Hi,

You need to make sure that it has FTDI or Prolific usb to serial convertor chips.

I think these are the only brand of chips that have drivers.

I bought one that has ch341 usb to serial chip in it and it doesn't work.

torque wiki has some info on adaptors:

http://torque-bhp.com/wiki/Bluetooth_Adapters

f you are using the USB version of this adapter then be aware that you will need to make sure the adapter uses an FTDI or Prolific usb to serial converter chip and have an android device running Android 3.1 or 4.0(or above) and supports USB host mode - you will also need the Pro version of Torque for USB support (though this will be ported to the lite app eventually)

Can someone with working USB adaptors please confirm what USB serial chip is in their unit. Easiest way would be to see what driver is installed in windows....
[MTCB Android Head Units Q&A] antfros:
Yes my v2.0.8 is in this package

[MTCB Android Head Units Q&A] mikochu:
I just tried my Rosstech MicroCAN cable ($250 VAGCOM cable) and Torque recognized it having a FTDI chipset. However, I couldn't get it to read anything. Torque kept nagging me about the baud rate, but I couldn't find a speed where it would work. I'll look around for another cable...

You device KLD? If yes, then set only MCU 1.98, the problem should disappear.
[MTCB Android Head Units Q&A] zaphod2:
RDS test may be because I have set a size of 220 in the "build.prop".

but why should MHZ small I do not understand.

with the umspringen of FM1 FM2 ... ... FM3 ... I can change anything, that is. since you can only either "band" or arrow push up / down.

for where the send name is too high. here's another version and please try and please send us pictures.

Update

Hi, I updated my KGL radio with codu's Android 4.4 image. But I chose a wrong MCU image (KGL4 instead of KGL). So I would like to flash the correct one (I believe the v1.99 is the latest KGL MCU). So I placed the new mcu.img and update.img on the GPS SD card but nothing happens. The radio does not ask me if I want to run an update. How can I update it now?
[MTCB Android Head Units Q&A] RmXsTyLe:
1. if u want to flash mcu's only you need not flash an update.img 2. easiest way to flash an mcu without an complete update is to flash the mcu in recovery 3. the easiest way to get into recovery is to download an app called reboot recovery (or like) and let the app reboots the device into recovery, there u can chose to flash an update from sd and he will find the mcu.img and flash it. done

Hey guys,

still can't let loose this bad radio reception issue :) I am using a usb dongle now and the reception is just like it should be only the wavesink UI is not very user friendly the design is ugly. In the factory settings it's possible to choose different radio chips as default chip. So i was thinking, is it possible to set the usb dongle as default radio chip?

[MTCB Android Head Units Q&A] jugi:
-Thanks very much, i will try this version and return with screenshot / comment

-Usually most radio stations has RDS NAME so its much more convenient than MHZ number.

-As my car SW has only volume UP/DOWN and prev/next buttons pressing next will only loop with the certain FM1,FM2,FM3 segments.

-it would be much more better to just move to next fm segment when you are in the end of previous FM segment.

*sigh* So, I will try the Torque recommendation but it's not optimal. I really don't want to fiddle around while driving if I want to pull some data before a run. (car's pretty damn modified)

Now I have bigger problems, lots of app crashes. I wasn't having this problem before but it's crept up and now has become more frequent.

Hi,

Is it possible to get ch341 serial to USB convertor driver ported in, so that ODBII dongle with this chip in it can be detected?

There seems to be driver information around and information that it can be done. This is a kernel driver.

Sorry if this has been asked but I couldn't find anything searching. This is just a general question. How nervous or concerned are you about attaching your primary gmail account to these head units. The fact that they come from china and we have no insight into what is being built into them has me a little nervous. I created a dummy account when setting up the unit but I would like to setup my google account so I have access to Play Music. Right now, I am just streaming through bluetooth. However, I want to use bluetooth with torque.

I am running one of the builds of 4.4.4 but I assume all the drivers are stock from the company making these units.

same iGO that worked before!!! :confused:
[MTCB Android Head Units Q&A] nook'r:
There is so much confusion about the the MCUs that people are flashing their units with.

Exemple, my unit JY model 8811 comes with v2.07, the buttons on the side of the unit are not the same as KD-C0659. both are for Toyota Camry but their actual buttons have different layout.

JY-8811 doesnt have a "home, back, Navi, etc..) while KD-C0659 does. so flashing the MCU from one unit to the other will only make things more complicated. most likely a person will end up with dead buttons or worst a unit not responding.

Best in my opinion is to flash the unit with the same firmware from same line of units.
[MTCB Android Head Units Q&A] typos1:
You can use BT with Torque if you want, but USB to OBD is faster connecting and more secure than BT.

As for any concerns or nervousness about using your accounts, I m afraid I dont know what youre talking about, virtually every electronic product is made in China nowadays, branded or unbranded. For instance, if you bought an iphone would you have the same concerns ? Cos iphones come from China.

---------- Post added at 02:22 PM ---------- Previous post was at 02:18 PM ----------

There is a button mapping setting in factory settings. not heard of any confusion with MCUs, only that some people say that some versions work better than others, just experiment with the ones that match your unit type - JY, and no others, or your ll brick your device.
[MTCB Android Head Units Q&A] jleonar:
Yes, products are made in China but the product is designed and made for companies like Apple, Samsung, HTC, etc. Those companies are putting their reputation on the line when they build something in china.

There have been counterfeit "cisco" routers that have been sold that contain backdoors and all sorts of nasty stuff. Since I am not someone who is tearing the roms down and building them, I was hoping a developer could chime in on their thoughts on it.

[MTCB Android Head Units Q&A] typos1:
There is nothing to worry about with these units or indeed anything from China, ie ALL electronics, from known brands or unknown brands.

I have never heard it mentioned at all before, in years of visiting these forums, I have also never heard of any such problems being reported, either on XDA generally or in nearly a year of reading this thread.

No disrespect, but I think you are being unnecessarily paranoid

---------- Post added at 05:24 PM ---------- Previous post was at 05:20 PM ----------

Go into factory settings and try the different keymap settings available.

There is NOTHING to worry about if you update the MCU image, people do it all the time, the only time there has been a problem is if you flash an MCU from the wrong manufacturer, the worst that is likely to happen if you flash an MCU fro the correct manufacturer is some functions do not work properly, so you just go back to a version that did work.

I can't post links because of my new user status but there are numerous instances of backdoors being installed onto consumer products coming out of China. And it has typically been very little known companies doing it. Just search on google for backdoors chinese equipment.

It has happened. It isn't being overly paranoid when you keep a lot of information in the various different google services. If these units had a brand name behind them, then I wouldn't be nearly as concerned but even companies like netgear have been caught with backdoors.
[MTCB Android Head Units Q&A] coudu:
The biggest backdoor in those device is google services themselves :p
[MTCB Android Head Units Q&A] agentdr8:
Pretty hard to do without the kernel source for these units.

You can reverse-engineer all of the MTC-proprietary apps that are part of these system images. While I haven't gone through it extensively to look for backdoors/malicious code, there doesn't appear to be any nefarious stuff in the code that I have looked at. There is the RkUpdater service that could potentially look for OTAs, but it's main purpose is to scan the sdcard for the update.img files.

If you're that paranoid, you could probably install any of the root-based firewall apps out there and block all traffic to any non-home country destinations.

Unfortunately this doesn't seem to be possible. I tried 2 different programs that should allow to reboot to recovery but they just rebooted my radio.

After the update to 4.4 something very strange happened. If I turn on the radio, the screen remains black until about 5 seconds before booting ends. Then if I turn off the screen there is no way tu turn it on again. I had to turn off car engine, remove keys, wait a couple minutes and then start again. It didn't happened right after the update, it intially worked normaly. But now it behaves like this and have absolutely no idea what could I do. I'll try a factory reset but that's my last idea. :(

Why is the update (system and MCU images on SD card) not recognized automatically and installed? What could have happened?

What's the "freezing screen after cold reboot"?
[MTCB Android Head Units Q&A] nook'r:
Once your headunit boots, it will take 5-10 second before the screen responds to any of your inputs, the screen actually registers your command like clicking menu, app icons etc but it will not respond (open the app) immediately . You will have to wait until the GPS locks on to your location.

What is happening in the background it could be a module is taking too long to load .

As i said earlier, i 'll deal with slow response than constant crash ES file explorer or no navigation software.
