Yes, I m aware of all the different permutations, its highly likely as has been said before, that a variety of companies make these units and modify things, both hard and software.

Not even HuiFei mention Toshiba chips, so were not certain that they have them either.

Its also very likely that HuiFei is just one of the companies making and moddying these - theres no proof so far that they are the originator of these units or the people supplying the parts/knowledge for others to make them.

Unless someone can obtain proof otherwise, its my guess that they all have the STMicroelcetronics audio chip as you pointed out.

I never said that you said that STMicroelectronics were a cheapo Chinese company, I just pointed out that they werent.

thanks for the correction. I did see your posting about the module, I think ill try my bypass switch and see how that works. ill pull the key, push a button and bypass the canbus unit that's not properly functioning. the trick is to flip that switch back before I restart the car haha

Hey! These are the measurements:

Wide bezel: 182x103 mm

Front bezel: 177x100 mm

I think that only the wide part matters, because the whole black frame is a one piece plastic.

One thing is annoying about this unit is that the screen is about 10 mm sunken in so it is a bit difficult to touch the screen around the edges.

My car's not of any importance here (Dacia Duster) as my AN21 still serves me well; my friends' car where he would want to have this Joying 7inch screen kind of unit build into is a Renault Meganne (version unknown to me, it's the original "fat a**" Meganne with the odd looking rear). The current radio is a 1din affair, but there's room underneath already provided by the manufacturer to accommodate a 2din unit so that's an easy modification.

But the width of the whole thing is what I'm worrying about.

Hence I"m hoping for an answer regarding that units' size so I have a good picture of what the situation, and maybe it's wiser to go for a 6,2 unit instead -although I understand him, a 7" is indeed nicer-. If that unit is really 180x100 I can fit it with some rework. If it turnes out to be 192x105 or something, things get more complicated.
[MTCB Android Head Units Q&A] Nyehehe:
Yes I did know that the ROM I installed was for Klyde unit. It was a bit difficult to find though this fully rooted and flashable one for 1024*600 screen, because at the beginning there is that "How to upgrade your system" explanation, but if you follow the repository or the Google Drive it's hard to find which one is rooted and which one not. Coudu's says it's rooted, but I flashed it twice and I did not get root access, instead I used Malaysk's ROM which was fully functional after flashing it. The SuperSU got root access after a normal reboot. During the flashing process the progress was stuck for about 15 minutes at about 15-20% so I just pushed the reset button to start it over and this time it worked great.

So this thread maybe deserves an extra note in that first post for the real newbies like me :) http://xdaforums.com/showpost.php?p=58249825&postcount=7614

This is a great community, I appreciate your time and talent guys who are working with these projects to give us better user experience with our units!

1) No, the stock music player is a piece of turd, don't even try using it. I hooked up my old iPod Classic 80GB to it, and all it did was read the files as they are on the iPod, meaning that weird file-system that iTunes creates with four-letter filenames hidden in hidden folders in "iPod_Control". No covers, no sorting, nothing. PowerAmp, on the other hand, is a badass application - awesome player, that will scan your iPod's library and sort it according to tags (artist, album, everything), it will show covers, and has a cool EQ system, basically great. You should get it immediately if you plan on listening to your music collection in your car, but then again, the sound quality overall isn't great, so I'd suggest rooting it right away and reading up on using Viper for Android....

2) Radio stations - yes, RDS info - I think that's pretty much it.

3) Yes, but only if your car already has such display options already implemented. This means that if the factory HU/whatever shows this kind of info, it will also show up on your KGL HU.

4) Radio tuners aren't of great quality in these units, in Audis the problem is especially evident because the radio antenna is embedded in windshields. Use a 2-channel active radio separator instead of the one you get with the HU. We only use those on Audi's with differing results - sometimes the radio works alright, sometimes there are problems with the reception, etc.

5) Good question. Probably not

6) I think that if you go from the stock Music app to Radio the first one will quit/mute, while going from PowerAmp to Radio might leave PowerAmp on.

As a side note, I've noticed that the radio app is kind of sitting in it's own place in the HU, maybe the MCU (somebody with a lot more technical knowledge has to confirm this) because when I had the radio ON and playing, and insterted an SD card with the update and chose Install, the radio reset to go into update mode,

with the radio still playing

, and just got stuck at the "Navigation System" logo. Weird, huh?

7) I think it's stored permanently, you just have to keep your phone paired and keep it updated in terms of new contacts, etc.

8) Yes.

Hi. I have question - in my radio with mcu version - MTCB-GS-V2.08 rk3066-eng4.4.4 24122014.16:58:26.

Which soft I can use and which you all are recommending for this unit ? :) Is it worth to upgrade ?

Right, I was only asking to see if I could suggest a version that would fit. Some of the companies do do versions specifically for the Megane with the nice arse (I always liked that rear end !) :

It would save him the trouble of making a universal unit fit. Those links say they are 7", I checked some others and they say it as well, although I know they put the wrong size in sometimes.

---------- Post added at 11:36 AM ---------- Previous post was at 11:32 AM ----------

The stock music app has nothing to do with ipods, its the stock ipod app that plays them.

Cant comment on it cos I dont have an ipod, but personally I like the stock music player, apart from the way it arranges folders. Everyones different though and I guess that the beauty of these units - youve got a massive choice of apps if you dont like the stock ones.

---------- Post added at 11:45 AM ---------- Previous post was at 11:43 AM ----------

I got no problem reading - if I want to search for something I may have to think of different words that mean the same or similar things, not every one will use the words "dash" and "cam" when referring to using a camera with these units.
[MTCB Android Head Units Q&A] NaviPR:
Agreed!

The stock iPod app just said "No Lrc file!" and quit after one second, not to mention it looked just like the stock music app.

It may have been because I'm using an iPod that is old by today's standards (and probably the one and only actually useful Apple product I have encountered in my life), so perhaps 6th gen Classics are not supported? They even stopped making them...
[MTCB Android Head Units Q&A] kaween:
Thank you sir for this info. I really appreciate it !

The 'sunk in' mounting of the screen is true for many units. But I've seen and read too many complaints about the "flush flat ones with touch sensitive keys" to take those in account.

Bluetooth communication "cancelling out"?

Hey guys,

when using the Bluetooth hands-free system it seems that there is a weird problem, with signals kind of "cancelling out" one another... for example, when person A is speaking, person B can hear them OK, but if person B starts speaking at the same time as person A, person A gets cancelled out... seems like there is some sort of interference... can't the phone interface accept two inputs at once, or is it just the case with Bluetooth modules, or what...?

Thanks for any help regarding this matter...

No, its not a HuiFei, its a Joyous, this thread is not just for HuiFeis its for all RK3066 units (and for the same units with RK3188 processors, I cant say "All RK3188 units" though as there are some that are some RK3188 units around not related to the units in this thread, but there are no other RK3066 units around.

There is at least one person with that unit in this thread, nothing you can do about the 30 sec boot time really, CAN Bus works ok, depending on your car model some VWs work, some dont.

[MTCB Android Head Units Q&A] ga!nusha:
So far it is not possible to have quicker boot times. Personally, i have not found it to be that long. i always keep the engine running for 4-5 minutes before taking off so it doesn't bother me at all.

It depends on your model, I would use the thread search, it has been mentioned a lot and there are pictures of air con, door opened warnings and MFDs displaying info from the unit, but its a long thread and I cannot remember every time it has been mentioned, I would have to use the thread search to find them and then tell you what post numbers they are, but thats something you can easily do.

You have to properly set your GAIN on the amplifier of the subwoofer.

After it is properly set, if you still don't like it you have to get a more powerfull subwoofer.
[MTCB Android Head Units Q&A] agentdr8:
The radio chip is controlled by the MCU via the Android app. It routes its audio out through the amp (and dsp if these have one), so it's possible to have it playing when the system (android) is not running.

Highly unlikely that this can be implemented. The limiting factor being the MCU.

Little off topic but that´s bad for the car specially on cold starts, recomendation is to start driving right away after starting engine but only not stress it until reaching operational temperature.

[MTCB Android Head Units Q&A] patagonia1:
Yep, during idling combustion is far less than optimal son carbon buildups grow easier and oil last less. Cold idling is worst as engine does not have proper lubrication causing premature wear, when you leave engine idling to warmup it takes much longer than driving it so more wear, usualy makers now recommend leaving idle just to allow oil to reach every part and them go driving as it will decrease cold working time, just drive like a grandmother till it gets warm. To much cold starts and idle driving (heavy traffic) are usually considered severe driving and require more mantainance in makers schedules. With turbo its the same, just not rev to much...only for stopping the engine care has to be taken if the car has been reving to let the turbo spin down and cool down with lubrication.

I m no developer, but something on my to do list is to try and make a better widget, with a different layout/colour scheme, that takes up less space (at least less space than the Klyde widget - its bigger than the others) and that displays RDS station info NOT the frequency.

I also want to slightly modify the TV app so it doesnt close when you press home (it closes when you press home or back) and so when you do this it sends channel info to the widget like the radio app does, so its possible to listen to digital radio via TV without having to put up with the rubbish TV interface.

Guess you could also try and add an alternative music player to the list of inputs as well, though it may not be as easy as modifying the TV app.

The KGL widgets are separate for each app (music/radio/ipod/BT music) the others are built into the launcher and auto switch the app that they display info from as you change source. Not sure which I would try and base it on, I guess having it as an app like the KGL, but like the KLD/KYD/JY in that it automatically switches between radio/music/ipod/BT music/TV or any other music player, rather than have a separate app for each like the KGL. This would also mean you would not be tied to the built in launchers (as you are with the KLD/KYD/JY launchers and could still see the widget for MCU apps.

Anyway as I m no developer it might take me a while ! Unless someone wants to help me do it ?

First mods completed!!!

Well I broke into the case finally and installed an external Wifi pigtail. The cable was a little short so I had to move the GPS antenna lead to one of the unused DTV spots, and use it's location for the Wifi. I picked up an omnidirectional antenna. Reception is much better now! I also installed some heat sinks on the rockchip and ram chips while I was in there. Figured it couldn't hurt...

I've been trying to get the IR working and that mystery has been solved. My unit has no IR phototransitor on the board, the holes are in the faceplate, but the solder point underneath is empty.

I haven't had a chance to check the performance of my external mic jack to see if I need to mod that. My board seems different than the photos posted on here. I can't find the C32 capacitor that is removed for the mod. Anyway I'll cross that bridge when I get to it...

Finally, I received my USB hub. Seems well built and is quite compact. In the photo, that is a standard business card on top.
