[MTCB Android Head Units Q&A] agentdr8:
If your headunit is capable of completely turning the backlight off with the value at 0, I would recommend setting it in the 5-10 range so that it isn't completely dark.

I'm hoping the developer of Screen Filter adds a broadcast receiver to his module, which would allow me to integrate a user-customizable screen filter overlay to be enabled during the dimming period. This would make it so the backlight could stay on a bit brighter, but not seem as bright to the driver by using a grayish filter value.

Dears,

I'm trying to install 4.4.4 800x400 KLD on my KGL device.

Installation aborted, cannot find rkimage or invalid image.

Should I wait for KGL version?

Look at the end of my post, if you are already rooted and on a KITKAT FW you can backup and restore data.

root is needed to install TWRP and JB datas will give a bootloop on KK FW.

No android versions are compatible with all devices (mcu ARE NOT). Either your download is corrupted or you did not put update.img at the root of your external SD / usb key.

Dear, I have downloaded 2 times and cross checked md5.

Can't get it to update, at first it would boot into recovery and then fail, stating there was no SD card to mount. Tried several times, then it stopped booting to recovery, just get a black screen.

[MTCB Android Head Units Q&A] ultradj83:
Same happened to me.

Download it again with a computer connected via Ethernet, extract update.img to your hard drive, copy it to sd and check md5 for the hard drive file and sd file match.

Switch off your device, insert sd into gps slot and start the device.

Let it prompt for update and confirm.

This worked for me.

Hey folks,

I recently installed an Eonon GA5153 (Klyde!) and I have couda's v4 firmware installed. I've got a OnePlus One, so I'm not used to SD storage on Android. I use Spotify for music and it looks like it saves the offline music to my 32gb Sandisk Micro SDHC(XC?) card. It takes my head unit about 18-20 seconds to boot up (from what I remember). Spotify crashes until the system is finished indexing the Micro SD card. I have about 1.25gb of Spotify data on the SD card and seems like it takes 2-3 minutes to be able to run Spotify. Is this normal operation? Is there a QuickBoot option?

Thanks,

Mike

Edit: Huh. I had to go to another office about a mile away. I started my car and the head unit booted up. Spotify wouldn't open until I got to the parking lot. I turned off the car, the head unit turned off, then I went to my meeting. An hour later, I came back to my car and started it. The head unit booted up straight to Spotify and the music played fine. Weird?

Use the reset button and power, it can be hard to work out exactly what order to press the buttons in, so maybe install an app that does it, like quickboot.

I've been test driving your 800x480 version for whole day on my KLD unit and there are a lot of issues. Google play service forcecloses all the time. Google contact sync gives an error. Most of the apps that I installed also forceclose and can't be used. So for me it's not suitable as a daily driver. On the plus side BT OBD does work and sound is a lot better than on 4.2 version ;)

[MTCB Android Head Units Q&A] typos1:
What do you mean "RDS info" ? -You mean it shows the station name on the button of each preset ?

This is how it is supposed to be !

It is more desirable for most people to have the station name than to have the frequency. If you see the name you do not have to worry about the frequency, radio stations have names and thats what people remember, not the frequency. Unless of course the frequency is the station name, but in this case it will show up as "98.2 FM" or whatever. This is a major feature of FM and it is in DAB too, also on internet radio you search for the station name, not the station frequency. And of course the frequency will change as you move around your country, if it is a national station you are listening to, so the station name is much easier as you do not have to try and find out what frequency it is on when you are in an unfamiliar area.

Yes I know what are CANBUS boxes for. I just want to say on the EONON GA5151 CANBUS box you can read exactly the same as on my Klyde. (KLD..., Software: KLD...)

I installed my Klyde (Mazda 3 2004-2009)head unit today... at least I connected it to my car. I can't order the cables to fit the HU. There is not enough space, but I will try again tomorrow. I just took some test, I had not much time:

- The WiFi can't find any networks, but there is at least three. But the truth is, I didn't connected the GPS antenna yet. Could it be the antenna for the WiFi too?

- Radio works, but weaker than the factory one. There is a single antenna connector, no wires for amplifier in the car. This could be working? http://www.ebay.com/itm/Car-Antenna-Radio-FM-AM-Signal-Amp-Amplifier-Booster-/220831228507

- Can I disable the beep sound when the HU boot up and when press buttons?

- I can't set the clock/step in the board computer on cars display. This should be working if I press and hold the MODE button for 3 secs on the steering wheel button and then with the NEXT/PREVIOUS buttons, but if I hold down the MODE button, the head unit changes the sources while I hold the button. I think this is not the HU's foult, because if I hold down the button, the CANBUS box shouldn't send the control signal to the HU.

I don't know which is the Rx and the Tx wires. I have no OBD and no Torque. If there is something what I can help you, feel free to ask.

Guys,

I've got two units, the first one was pretty easy to identify:

under MCU, it says: MTCB-KGL4-V2.01

So this is a KGL.

But the second one is pretty weird, under "about" it says:

MCU version: 4.3.10-3-61-040201

WiFi antenna is a short piece of wire inside the unit, some people have extended it, that may be the cause of your bad reception.

That antenna booster will sort out your radio problems (it did mine, but it isnt actually a booster, its a power injector - it injects power into your aerial line so the booster in your aerial can work, your OEM headunit did this, but most aftermarket ones do not).

I dont think you can disable the beep sound.

I have heard about similar probs with built in clocks before, not sure the way round this, other than trying all options under CAN Bus in factory settings (including non Mazda ones, cant do any harm trying them if others dont work fully) or waiting until the Chinese update the MCU with more CAN Bus options for more cars. Or as you say the cAN Bus box is sending the signals wrong, maybe contact your seller ?

Well, yes what would help me is a picture of the little black socket that plugs into the KLD unit (the main one with power and CAN Bus leads etc) - so I know what colour the CAN bus lines are and a pic of the wires going into and out of the CAN bus box, I m trying to find out which wires are CAN Tx./high and CAN Rx/Low. My car has CAN Bus but I dont actually need a CAN Bus adapter as the SWC is resistive and I can get illumination, reverse and brake from the car without an adapter (its 15 yeras old, one of the first cars with CAN Bus, probably a more basic system).

(PS, I ve heard of Tatabanya because the next town from me, literally a mile away, is twinned with it, so I drive past a sign saying "twinned with Tatabanya" quite often !!)

[MTCB Android Head Units Q&A] goolac:
Some areas have radio stations that do not use the newer RDS standards and broadcast the RDS info in a single stream. The buttons will show any of that info which can be the station name, current artist or current song that was playing when the preset is set. Only one of the stations in my area actually shows the name of the station the rest are gibberish of partial names of artists/songs etc. This has been this way since the android radio app has been created. I wish we could rename the preset to what we wanted. That would be the cat's meow.

Oh, I see, should only show station name, when these units first came out they did not show station names on the preset buttons, this was changed early on and on 4.2 and 4.4.2 on my unit, it DOES show station names, cant say for 4.4.4, my unit is still on the bench. you could edit the app and make them say what you want, I m sure someone actually did that once.

**NO NEED FOR A WARNING THESE ADAPTORS/POWER INJECTORS ARE FINE**

Some car's standard headunits inject power into the aerial lead to power the aerial's built in booster, an aftermarket headunit will not do this, adding one of these little devices will improve your signal because it allows the factory antenna booster to work, I know this from experience and way before I even got this unit I wondered why there was a power lead to my antenna. My signal was much better after fitting one of these.

The android changes from 4.4.2 to 4.4.4 do not really concern me, as the main change was fixing the Heartbeat bug which really shouldnt be a concern on a radio for most people.

To me the 9 Band EQ and better sound quality are interesting. This issue is, I have modified much of my KGL 1024 x 600 unit to take full advantage of the 1024 x 600 screen, by setting DPI to 160, modifiying Framework-res.apk so the status bar is usable as that DPI. modifying MTCRadio and MTCDVD to use that resolution. Plus some additional android settings to support the resolution fully. (i.e. Tablet UI, etc) I have also modified many of the certificates, etc that my unit looks just like a Samsung Tablet to google, so I have zero problems with the Play Store, etc.

As far as thing like the stock Music Player, Video Player, etc.. They have all be deleted and replaced with stuff from the Play Store, such as Google Music, VLC, etc. Google Music at 1024 x 600 true resolution is awesome.

I guess I need to download the new 4.4.4 and see what it will take to modify to where I am at now. Glad to have TWRP to have a full 4.4.2 backup. :)

This is a great app. Just two comments at the moment - it doesn't appear to honour mute status on the head unit, so when volume is 0 it will be raised as the car goes faster.

Also there needs to be a way of adjusting the threshold for each change as some cars are noisier than others.

[MTCB Android Head Units Q&A] typos1:
I know which 2 they are on the headunit, they are the ones I ve labelled in my edit of your picture, I just dont know which one is High and which one is Low.

From the pictures I ve seen on the internet and the people who have used CAN Bus adapters NOT supplied by Klyde or HuiFei, plus the MTC CAN Bus app on the unit, I deduced that the headunit talks to the CAN Bus directly and that adapter just gets reverse, park brake, speed pulse illumination etc from the car and sends them to the head unit.

I was thinking that the cAN Bus wires from the car bypassed the adapter and went to the headunt directly, supporting what I d deduced above, but I was wrong.

---------- Post added at 01:24 AM ---------- Previous post was at 01:12 AM ----------

You are right, the headunit directly can listen to can messages that are broadcasted on this canbus (usually the Infortainment CanBus (Yes there are usually several CanBuses within the car, working at different speed)), you can then get infos from A/C controller, dual canbus ect ... This can work totally without the Canbus box.

The canbus box also "listen" to CanBus messages, and convert thoses messages into analog things (power to reverse wire, brake wire, handle ignition status ect ...).
[MTCB Android Head Units Q&A] agentdr8:
The 4.4.4 permissions changes shouldn't affect the MTCRadio app. It stores its preferences in /data/data/com.microntek.radio/shared_prefs.

If you're using XposedMTC, and you enable the preference to restore radio presets but don't actually use the "Learn presets", then it would reset your stations to defaults when it sees the radio service calling the resetRadioPreference() method.

As for your audio problem, I have heard this complaint before, but I m afraid I cant remember who had it or the solution, I can only suggest a thread search or that you take your unit apart and see if anything is loose, or looks wrong, KGLs have suffered from poor or non-existent radio sound before and its turned to be a loose or unconnected aerial lead.
