With all respect, if it seems to you that viper is not affecting the sound too much I am pretty sure it is not really working, are you sure the installation went OK and driver shows to you like it is working? Viper is the holy grail, maybe not the easier app out there but if you take some time to configure it and you are actually not deaf you are going to love it for sure, you don't really need anything else!

When I first bought my HU I was unsure about the sound quality of a Chinese unit compared with the big names, when I received it I was glad to find that quality was not bad at all but still I was thinking to replace my stock speakers until I installed viper on it ) would never imagined that these speakers could actually sound so good and spit such wonderful bass )))) I had to battle doors vibrations due to the outrageous bass I am getting but now I can say I love to listen music in my car!

Best regards

Sygic

Has anyone managed to get Sygic successfully working? I've installed it but it just gets stuck on "Manage Maps" with a loading circle which eventually disappears. Any help would be appreciated!

Thanks.

That's the interesting part. I don't lose any other settings, not even the radio stations.

I also realized when I set a custom setting in the amplifier, change the high, mid, etc, quit the app with the back button, then open the amplifier app again, and the custom setting has totally different setting on high mid low as it was a minute ago.

If I don't quite the app with the back button but press the home button the settings are still there.. until the reboot or until i quote the amplifier app.

I just finished my new harness with my axxess canbus, will photo it and post it shortly

Going to use my own ground and see if it helps with the tump off issue. If not wwill usevrhe factory ground and chop off my extended wire with eyelet connector
[MTCB Android Head Units Q&A] kwalsh24:
Radio is in with the new canbus, all issues with the unit powering off randomly with key off engine are resolved :D. Radio stays in till the key is removed. I also now have constant button backlight on as I wired the illumination to the accessory line.

Unfortunately I still have the thump on engine start if the radio is already on :( but no longer have the thump on power off as I have the amp turning on via a non used accessory wire at the canbus. Only have my antenna adapter running off the radios amp out wire....

Ill live with the thump, unless anyone can think of a fix for that. Its the radio itself putting feedback thru the RCA, almost like its muting the music at engine start which could be causing the feedback?

hey guys, here is 1.90 firmware for Hot Audio (GS) Unit's!

fixed some Russian tranlsation, but has some new issues with radio, radio get's too quite.

My car is a 2011 Viano.

I changed the adapter and it's a bit better now but still does not match the OEM by far.

If I could solve this, the device would be great.

Hello everyone, I am using this unit on my Golf MK6 since 15th of may and without any firmware update, I had some issues with the backup camera, image was rolling constantly, but solved the problem with a CCTV ground loop isolator after many tries with different hardware, if someone is interested here is the isolator:

http://www.ebay.com/itm/161311794235

You also need 2 different BNC to RCA connectors for this isolators.

This is where I got my unit, and so far I can see it is a KGL (HuiFei) unit.

http://www.ebay.com/itm/201056209800

I am very impressed about the stability of the unit, we drove 2 weeks ago with two drivers almost 42 hours nonstop while running tomtom and Rocketplayer as Music player, each destination in tomtom was set to around 1000km’s and unit ran perfectly without any lag or crashes.

Everything works perfect but only radio does not receive signals perfectly, I am pretty sure it has nothing to do with the radio but the antennas in Golf MK6 give me headaches, I did try different antenna connectors but still no go, if I am near a radio station the reception is good, till I drive away, If someone has a solution or suggestion for right antenna adaptor I would really appreciate it.

This is how my antenna cable looks like in the car:

Here some pictures of my unit:

I just figured out that the Bass setting is saved as Treble and the Treble is saved as Bass when I quite the Amplifier app.

Look at the video I took

[YOUTUBE]V4_ENal9he4[/YOUTUBE]

It's interesting that the sliders are working correctly Tre modified the Treble but as soon as I quite the Treble is saved as Bass and the other way around. Mid seems to be fine.

Anyone with the same issue?

Mayalsk 1024x600 pre-rooted ROMs

Hello all. I'm sort of a newb here. Hopefully someone here can help. After flashing Mayalsk 1024x600 pre-rooted ROM to my HU (Joying, RK3188, 1024x600, Quad-Core, KitKat 4.4.4), my NAND Flash disappears. It is non existent in settings and in the root file system. This is disappointing for obvious reasons. The ROM itself works great! Love the modded UI, animations, apps, etc. but would really love to have this corrected. If I flash the original ROM back, the NAND flash reappears. Any suggestions? Anyone else have this issue? Are there any steps that need to be taken after ROM installation that will correct this? Any help would be greatly appreciated. TIA! :)

There were no errors all completed successfully. I will battle with it, do you know if I can use just the sub out to plug in a sub on the unit, using the cars wiring

Just taken the unit apart to make sure I have the right radio chip and found it to be the TEF6686, after another flash the radio works but is not as sensitive as the factory version.

The version was kld1-2.67 however the latest release on here was 2.55 - a little confused about that my new unit had a later version?

There's an option in XMTC to get rid of the stock volume display dialog (and puts volume info into the statusbar as text). That's the only thing that would potentially cause issues. I don't believe it's enabled by default.

Have you installed an MCU recently? Maybe it's the wrong one, or doesn't work as well as the one that came with your unit.
[MTCB Android Head Units Q&A] Profane4711:
I installed the newest KYD (2.59?) MCU. I think it has to be something with the ROM, because the MCU worked good with the last ROM.

So I still have this unit (it's the new JY RK3188/1024) on my desk for bench testing. It sounds like everybody suggest to do the microphone mod?!

My only concern with doing the microphone mod is somebody said that the microphone on the headunit is awful and won't work good with Google Now... Is there a microphone mod that disconnects the headunit mic and reroutes it to an external mic?

[MENTION=367862]Telemachus[/MENTION]Did you get your noise canceling microphones installed? Were you able to place the board in the back of the unit or inside of the unit, then connect the external mic wires to the board?

And something interesting one from me, but it is only posted on Russian forum 4pda.ru.

Anyways, there are many pictures and screenshots.

In short, it is about comprehensive and direct control over Sound Processor chip BD37534FV and alike, requiring some (minor) hardware mod.

If community here will become interested in this mod, I'll try to translate to English (but it'll be hard to me).

[MTCB Android Head Units Q&A] Telemachus:
Internal mic works MUCH better after the mic mod. Google now will catch your voice if car environment is quiet.

I bought several mics on Amazon, and the Clarion mic seemed to work best. It doesn't really reduce outside noise, but it picks up voice much better. I would actually be done there, but the bluetooth itself disconnects every minute or so for a few seconds, then reconnects. I am hoping reverting back to the MCU that came on the radio will fix that, although I cannot find KGL 2.55 without audio mod.

I got an Olympus noise reducing mic that will be interesting to try, but I will need to insert 5 volts into it with a resistor and filtering cap... so that will be a project for another time.

I'm still not sure if ROUT and LOUT deliver analog audio to the MCU as I suspect they do. If so, the entire MIC itself would be replaced with a separate Electret Mic board that sends audio to the MCU.

If and when you do open your unit to do the mic mod, I would LOVE to hear what happens if you connect the Lout or Rout on the BT board to a line input on a stereo (and perhaps the "other" sgnd pin 3 to the negative of the input). If it is analog audio, then we could easily bypass the crappy stock mic entirely.

Hello friend. Eureka, has finally worked. Herewith you catch.

Reviewing my actions, I think that I made a mistake: I did not create the folder "com.tomtom.gplay.navapp" in the external SD, but I'm not sure.

In short, it works. But I've seen that in the internal SD has also created the same folder and with the same size (in this case downloaded map of Spain and Portugal, to not exhaust my mobile data rates). This is why it happens. Obviously you can not be so as soon as you download the map of Europe.

Just tested, looks good on 800x480 (Malaysk rom) :)
[MTCB Android Head Units Q&A] 7floor:
It really depends...

One can use fixed points (px) in layouts of their software, or use logical one (dip).

When using px, the element sizes would be equal in terms of physical pixels and thus different in terms of visible size on screen.

When using dip (as I did), elements would be scaled according to screen DPI (just like you said) and (hopefully) will look equally on both resolutions - but there is one pitfall: users are allowed to change DPI in their devices in screen settings; also different ROM authors may set different default DPI. So I was not sure completely as to 800x480 devices.

Hi everyone, I have a quick question. Ive just bought a Pumpkin headunit that runs Android 4.4.4 KDL2 800x600 1.6 ghz dual core Rockchip 3066 cortex A9. It seems to be the same procesor as the Original post is describing . Is it safe to say that I shouldn't have any issue if I flash the Malysk rom made for that version and KDL2 ? I understand that no one can give a definitive yes or no , but at least a "shouldn't be a problem " .

I'm no newcomer when it comes to flashing or modding Android. I've even built some CM roms. The only reason I ask is as we all know, we tie up a good bit of money in these things and don't want to lose said money. And who better to ask than the guys that have more experience with these particular devices.

One further question, abusing his kindness; I guess that all of this can also be applied to any Smartphone?

Well, maybe after the joy of TomTom GO the external SD performance; I have to ask other questions.

In my radio HuiFei I use GO, TomTom Iberia 1.4 and Sygic 15.5.3 navigation applications. Well, Sygic is installed simply by placing the Sygic on the GPS Card folder and running the application; but TomTom Iberia 1.4 forces me to install it in the internal memory.

Question: It is possible to do with TomTom Iberia 1.4 the same as with TomTom GO.

I think the answer is no, because there is an entry for TomTom in PCV Startup Builder only.

So I am still having a headache with my radio after flashing my unit.

The unit is a rk3066 dual core kld1 came from factory with v2.67

As advised I changed the mcu to kld1 with soundprocessor, the radio did not work with this mcu so used factory v 2.55 now the radio is playing and then stops then plays approx 5 seconds - sound stops then the radio continues. I am using the latest malaysk rom 101015.

How do I know that the mcu has applied?

Can I flash the kld1 with kld2 mcu as it states on the wiki that they may be interchangeable.Any success?

The kld1 factory rom 2.55 works but the radio is broke. Intermittent.

I have checked the radio chip too. I am more than at a loss. My poor sound from the unit is now compounded by a broken radio

I had a kld1 v2.67 which was on the unit purchased from the factory.

Will flashing with kld2/kld mcu cause bricking? If the factory don't supply an Mcu it is my only way forward :(
