I know it's not the same, but I have been using UI Tuner app (https://play.google.com/store/apps/details?id=com.bassel.uituner) to tweak the screen..

I've even pushed it up to 1280x720 without issue.

The app will let you change resolution and DPI on the fly to test settings and even lets you set it on a per app basis.

Currently I am running at 1024x800 with a DPI of 300.. Some of the stock apps are a little goofy (amplifier and torque) but over all everything runs without issue.[/QUOTE]

I didn't think to this.

I saw 1024x600 HU, the screen sharper end brighter, the characters are smoother, nicer.

The sellers of the aliexpress offer bigger resolution screen only 20USD extra cost. From this I think about this! How much the complete 1024x600 touchscreen?

the problem is not the blue cable or antenna amplifier . I have kgl for hyundai ix35 and I have the same problem with the function AF. I think it is problem of mcu

My original radio, has 12 V on the cable station.

I bought a power supply of Phonocar

carry the electrical diagram

I do not think it is a signal problem but logic.

- The tuner (in my case TEF 6624) Looking for a limited time the same issuer.

- If it is the issuer, proposes another.

all have two inputs FM tuner Modern.

usually one is what we hear, the other serves to constantly scan the network, and search for an alternative frequency (of the same issuer !!)

// Look at the pdf of the TEF 6606 of my old post, page 10.

there are settings,

AF UPDATE

AF Jump

AF Check

by behavior, I think the radio face research, and priority has "less time without music" -> AF Jump.

I think for us the correct setting is AF Check. -> Find the same broadcaster, and it does not matter if I do not listen to music in the meantime.

(Who does not live in an area like Italy, can not understand this need, there are areas where in 20 Km changing a 4 radio frequencies and have many tunnels where you do not get anything)

should be able to be a choice to make in setting machine (where you select the types of decoders used, logo car ect.

You can use either the wire 6, the wire 7, but you must have a device like the pattern I have attached. (Again you have to check if your machine has an amplified antenna)

otherwise do not need a power supply, but you need an amplifier.

I got a different Bluetooth ODB. Same situation. Scan for it it shows right up as OBDII and a serial # or something like that. Press connect and nothing. I have no other blutetooth devices paired with the unit.

Think I should go back to a stock rom and see if that does the trick?
[MTCB Android Head Units Q&A] comptechltd:
Yes, you are exactly right. What I am starting to notice though is button layout and location. They always seem to be just a bit different between makes and models. For example, some have 'Band' some have 'BND' on the button as well as actual location of the button on the HU. Some may have the 'back' key on the right bottom some may have it on the top left and some may not even have a back key. While not definitive by any means I am noticing that this is a way to HELP differentiate the models. I guess I am saying the basic 'STYLE' is the same, it's just when you start looking at the details. Again, in dealing with these it is NOT an exact science just may help to differentiate.

[MTCB Android Head Units Q&A] agentdr8:
If you're trying to pair an OBD adapter, it does not require PIN entry on the headunit. If you're trying to pair some other BT adapter that does require PIN entry, there's a good likelihood that it won't work, as these headunits don't support the majority of the BT profiles.

You can definitely try a stock 4.4.4 rom and see if the outcome is any different.

GPS Sound switch

Here I am again....

Tried yesterday to check GPS sound settings. It is set with SWITCH.

Anyway, switching sound works only with bluethoot phone call function.

Not working with

- DVD (both video and audio)

- SD Music

- Bluethoot music

- Radio

Not working means that GPS running on top and music in background. I am listening to music. I have a navigator call and after its speech the sound does not switch to the previous source and remain mute.

I have tried with Sygic and MapFactor, same result. With stock Maps navigator the sound is mixed (even if I set both SWITCH and MIXED setting in GPS).

Please help me....

With all these problems (radio, remote command...) it seems I own a very expensive small and big tablet :eek:

Here I am again, new JY HU.. some time spent to set it up again and root it.. now everything seems to be fine on Android 4.2.

The only difference is that I had to set HU power under keylock because of battery draining.

Now when I remove the car key, the HU power off.. No problems about that, but when I start the HU again, XposedMTC tries to restore Radio presets (cleared out by HU power off), it works but you have to launch radio app, wait like a minute, then close the app and start it again to see the presets at their place. Otherwise the radio is stuck on "AM 0kHz". Am I the only one with this strange behaviour?

[MTCB Android Head Units Q&A] fedmond31:
Hello, i have same problem, here is my understanding ?

Apparently Radio and TTS share same Android sound channel, so commute GPS sound is only working with non TTS voices (As IGO normal voices, i dont know about Sygic)

With IGO normal voices, Navigation sound makes radio mute and back after . (My HU came with IGO and nonTTS voices)

To use TTS Voice in IGO, i had to :

Make SVOX defaut TTS in Android, put volume at 200%

In HU "Factory settings" Audio: decrease radio to 0 and increase system to max=20

With these settings Navigation sound comes on top of radio and is louder; it is satisfactory enough to me.

mcu.img questions

so installed a rooted rom and i'm happy with the results. I have a JYunit and before my update my back up cam stopped coming on when i go in reverse. I understand the mcu controls this so i am wondering if i can install one of the two available updates, 2.08 or 2.11. my current mcu version is MTCB-JY-V2.16. so another question i have is are the two available modded? meaning could i expect a upgrade by going to one of these or is my version newer? and can i install the mcu.img by its self or do i have to install the rom with it?

[MTCB Android Head Units Q&A] comptechltd:
If you are running 2.16 yours is newer. As far as I am aware no one has been able to mod the MCU. Yes you can update just the MCU. If you search for my posts several pages back I gave a full explanation of how to do just the MCU. You can also find it explained on the first page of this thread. It only takes about 30 seconds.

[MTCB Android Head Units Q&A] wilianbastos:
Questions how do u have the 2.16 mcu?
[MTCB Android Head Units Q&A] typos1:
You can use ANY JY MCU if you have a JY unit, MCUs with higher numbers do not necessarily have newer or extra features, in fact sometimes the opposite is true, for instance after the update to KK some VW models had fully working 2 way CAN Bus, but ONLY with MCU version 1.77 (KGL), which was the oldest version. So my advice is to experiment with all the JY MCUs available and use the one that works best for you.

Just come across this:

http://www.aliexpress.com/store/pro...i-Bluetooth-Radio-1-0/612847_32231669540.html

Its the only pure Android single DIN unit I ve seen (only ever seen dual boot WinCE/Android ones previously) and it seems to be be a variant of the AN21-U so there should be support for it in that thread (I m assuming this as it has the same Mstar processor).
[MTCB Android Head Units Q&A] agentdr8:
That's normal behavior (see post here). The RadioService has to run once in the background in order to call the resetPreset() method, which then gets overridden by XMTC. Otherwise I have no way of knowing when the presets are lost, and when to restore them.

So when my Eonon unit arrived it came with 4.2.2 KLD-V2.20 MCU. When I was first playing with it and trying to figure out how I was going to be able to connect my Rockbox'd ipod, I plugged the iPod into one of the USB ports and launched PowerAmp. At that time, it pulled only a folder or two, but it played them very nicely. I upgraded the unit to coudu's 4.4.4. Since the upgrade, every time I plug the Rockbox'd iPod in, the HU will lock up then attempt to reboot. I will see the VW logo and it just sits there. If I unplug the iPod and then turn car off and back on, the HU restarts without any issues. I deleted the LOST.DIR folder from the iPod but it hasn't helped. Anyone have any ideas???

hy everyone

To update GS- with Android 4.4.4 started 4.2- MCU GS - 2.08 (downgrade from 2.20 )

Fixed problem with volume knobs and frequency!

I had selected the voice wheel3 (if you selected the knobs do not work well)

what they do:

- Rudder

- keymap

- TouchMap

// For the problem of connection to OBD:

- As some have suggested, I put the MCU to version 2.08.

- I tried to enter the codes of 0000 and 1234 BT connection.

(I had not tried it with 1234), I believe that the solution was this.

* perhaps did not need to downgrade the MCU

Let us know.

I hope to serve somebody.

Just a quick heads up. Using the latest version of XposedMTC but having a problem with dimming. It works great in the sense that it dims the brightness and starts up Screen Filter...but even with the sunrise/set daemon running and options enabled, it ALWAYS enables dim screen and screen filter. It never goes back to daytime mode.
[MTCB Android Head Units Q&A] agentdr8:
Odd. What do the start and end times show in the preferences? I'll run some tests to see if I can replicate the behavior.

Also, if you had upgraded to the latest beta from the previous beta, you might need to wipe XMTC data and reconfigure your settings. There were some file permissions being overwritten, so the prefs file could become unreadable and/or unwriteable, and the sunrise service might not be able to get proper data from it.
[MTCB Android Head Units Q&A] staneb:
I actualy have the same issue when fresh installing XMTC. My workaround is setting sunrise and sunset time manualy so that the screen is on full brightness and after that turning on the feature to automatically set sunrise/sunset time. Then it works. If I don't do it like that and enable the auto feature at first, sunrise/sunset time is set to current time and device dims the screen.

Also regarding XMTC obd feature, it just doesn't work for me from when you added setting the obd name for parring. Version 1.3 is the last version that pairs my Vgate OBD. So I install the 1.3 to pair my OBD and upgrade to latest experimental ;)

Ah, thanks for the feedback. I'll run through that scenario and try to figure out what needs to be fixed.

Still not sure why the BT override doesn't work; I basically took the stock methods and pass the string provided in the prefs instead of the default of string.contains("OBD"). There was a post earlier that said you have to change the PIN on the headunit to match the one the OBD adapter uses, and then it pairs. I never changed mine, but I guess my adapter uses the default of 0000.
