[MTCB Android Head Units Q&A] ptclabs:
on the KGL google cannot understand you at all. There is so much noise it just gives up. Watch the little vu meter bouncing around the google symbol, dead giveaway. On the GS google understands if you scream at it. Never liked screaming at my car "What is 300,000 yen in dollars" and watching the reactions of others sitting at the stop light. Crazy Gaigins everywhere. Now I just ask it what it is.

for call quality. KDL software on the KGL had a little better, but everyone knows you are on a speakerphone. You get the can you hear me comments constantly. We use these for business so it is not a solution. You are correct they can understand you, although you sound like you are speaking through a tube.

We just tested with the gs internal disconnected by clipping the tp wires and you can no longer tell it is a speakerphone even with a 1$ chinese microphone. (the microphone looks like a computer mouse cheap and good)

Do KGL's have wires running also or is it in the cabling? From what i can find on here it is in the cabling. If no one answers guess I will find out tomorrow when doing the wifeys.

I think not having a fan may have helped the GS have almost no noise at all when the internal is disconnected. VU meter stays flat until you make a sound.

Yes you say Klyde which retailer you mean?

or the factory direct?

How long should we wait for the fixed version?
[MTCB Android Head Units Q&A] ptclabs:
I only deal with the factories. I really need more info, pictures for them. I sent them everything I/everyone had on here. They know it is a problem and are happy to work to a solution, but they want a better understanding of what it is and to test it themselves. I think just not installing a internal and cutting the pathway might be a good option.

Many of the factories are having a problem getting to this site. I am guessing it made it to the china nono list so they cannot get here without a vpn. The chinese have a problem testing things like google voice as they do not have gmail/play store or anything.

Poweramp instead of standard player

Hi,

I've just installed a Erisin ES9782A in my Mercedes Viano after having problems with a Dynavin head unit.

Looks and works verry good. Possitive about the touch screen and start up time.

Steering wheel controls "answer call" and "end call" are not working. But thats not a big issue for me. "volume up" and "volume down" are working.

i am missing a play random button in the music app, so i would like to use another app instead.

Other people seem to have replaced the standard app with poweramp but after searching this thread I still have no idea how to do this.

Can somebody explain it to me?

Hmm okay, so the screen did the same thing this morning, however I did notice it was still dimmed to the lowest setting in the system settings, cranked it up and will see what happens. May have to flash back to HF firm&mcu before I go on my 12hr road trip tonight, what's the stabilest build currently? Are they past 2.02 in HF world?

I posted some pics of my KGL disassembled a while back. The internal mic is wired almost exactly the same as the pics of your GS, which oddly enough, differ from how the insides of my GS look, but that's probably due to different faceplate styles.

Good idea. I'll take a look at the Klyde apps.

Thanks for posting up the 2.1.1 version. I'll upload it and the older version to the Huifei FTP server in case the current links go down.

On a more serious note - I thought I read somewhere that the latest version doesnt work and you need the older version ?

Arguably, but you're correct, it's not an ideal place for the file to live. If you're not running Adblock and some semblance of active protection for anti-virus/anti-spyware (even defender/essentials is fine), though, you get what you get. However, those mitigating actions causes Firedrive to be completely nonfunctional.

The link I posted was someone else's link from a BMW forum in Germany. I can host this on Dropbox or something when I get to a PC, so that it's spam-free, but ultimately I'd love to see it on one of the repositories hosting the differing firmware revisions. A nice, centralized, trusted resource for everything huifei. A man can dream, right?

Since no one here maintains the GDrive that houses all of the different firmwares, it would probably be best to mirror that to the Huifei FTP server, which [MENTION=2067704]dark alex[/MENTION] has provided.

Thanks for explaining.

I am sure that I have seen tv boxes with two antenna but not sure if they are true diversity modules.

Coming back to trouble shooting my HU and all the issues I mentioned earlier, my seller sent me a link to

V2.03

MCU.

Now can any experienced member comment on

- IF V2.03 is stable and trouble free

- how to update it? On AN-21 it was easy. Go to advance settings and update. I cannot find any update option on these units

Thanks.
[MTCB Android Head Units Q&A] typos1:
Diversity is a setting in the software of the tuner, home based set top boxes probably wont have it, if its for a mobile DVB-T and its got 2 tuners, then its highly likely its diversity, as youre not so likely to want to watch one thing whilst recording another in a car.

Easy, put update on sd card, it should auto detect and ask if you want to update, if it doesnt auto detect, reboot and it should do then.

---------- Post added at 08:59 PM ---------- Previous post was at 08:54 PM ----------

I dont think pakidermo, the op, checks the forum much nowadays - I think hes tweaked his unit to how he likes it and is enjoying it. You could always pm him and ask him to post any update you have ?
[MTCB Android Head Units Q&A] NicolasGomez:
Also as a seperate question, do these units support 64gb sd cards or just upto 32 ?
[MTCB Android Head Units Q&A] Reptile-X:
It could be that we have stronger signal here, when I am driving around in a city I got decent signal, even on highway I got signal but fails to receive time to time and that makes it unwatchable.

The diagram on that sticker is a standard diagram I think like you said, even on my head unit the wire colors and such where not correct.

I took a photo of the wiring diagram back than, maybe it is usable for some guys here, but like I said it is not 100% correct. To make things clear this is from the HuiFei head unit.

---------- Post added at 11:01 PM ---------- Previous post was at 10:43 PM ----------

I would just switch the red and yellow wire and see what happens, yellow is constant 12V and red is ACC 12V and the problem you got with booting can be caused if those are switched, this was problem with many car radios even good brands back in late nineties, also Parrot carkits have this problem, but I am not 100% sure if that’s the case in your car, switching wires should be easy just to check.

The ground loop isolator comes between the wires from the radio to the sub itself, not between battery and radio.

Here some ground loop isolators from cheap to expensive.
[MTCB Android Head Units Q&A] typos1:
Think its supposed to be 32Gb, but it doesnt really matter as, if there is a limit imposed, it can be removed so they can read up 128mb sd card.

[MTCB Android Head Units Q&A] harlequin69:
Plenty of uk guys here but I don't think we have an answer for your question, I looked for a uk/Europe seller but ended up having to order from China anyway there was/is a seller in Germany but they only imported bmw spec huifei units.

Also I would like to address the common theme that huifei units have more issues. I deal with questions like this at work all the time, unless you know how many of each type of unit has been purchased you cannot make a call on failure rates. Huifei I would wager is the most popular and has a larger sample size and therefore more faults will be reported but the percentage of units with issues is probably fairly evenly distributed amongst the brands.

KGL microphone (easy fix)

just pulled apart the wives kgl. Wires are right in front clearly marked to snip out the front mic. KGL's mic goes through more ribbon cables than the GS which accounts for the worse performance. Also KGL has a fan. which makes it even worse.

Google can now understand me fine even in japanese. 1000% better.

Not saying the other fix does not work well, or even better, but this is quick and easy. 4 screws and a snip.

Hello everyone

I bought a Erisin 9753. For BMW E39

erisin.com/es9753a-7-pure-android-422-car-dvd-player-gps-obd-bmw-5er

Was supplied with the unit

MTCB-KGL5-V1.93

Model

S07

Android version

4.2.2_20140724

Kernel version

3.0.36+ root @ ubuntu772

Build number

rk30sdk-eng4.2.220140724

I have now read all the pages. I'm now totally confused. v1.93? KGL5?

Which update file (MCU) I have to use? Page1 says KGL1 for BMW ...

[MTCB Android Head Units Q&A] typos1:
The 32gb limit isnt really real as it can easily changed to a 1Tb limit with a simple mod and the only reason that Android doesnt ship with the ability to read 32Gb+ fat32 files out of the box is so the manufacturer does not have to pay Microsoft royalties. Plenty of info on XDA re this.

Lol, its certainly NOT semantics were playin !

Sayin these are fakes/copies/bootlegs/illegally copied when they are actually originals isnt semantics, quite the opposite, thats a MAJOR difference. Making a product that fits another company's product, in a style that matches the other company's product is not "knockoff" If I make a unique case to fit the iphone, I am not making a "knockoff" product, I am making an origianl product.

These are in no way copies, in fact these units are something that the Chinese actually have a lead over the established Western manufacturers on.

Dont wish to fall out a about it though :)

I have it too, I just haven't attempted to do it. I think these are just going to be sold without the feature. I don't see the value in de-soldering the defective diodes and replacing or bridging the pins. I also don't want to return the units just because of this. 3 of the 5 I have are for bench testing and 2 in-car demo test units.

On one hand, I was disappointed that the MFG shipped these with a defect. On the other hand, I was notified of the problem before the units were delivered, and they were up front and honest about the issue. They went out of their way to make sure I was aware and comfortable with what was going on, and did offer a free return and replacement of the units.

reading up on compiling kernels for RK3066

http://www.freaktab.com/showthread.php?4491-How-to-compile-your-own-kernel-for-rk3066-devices

Before we can begin to think about compiling a custom kernel for this device, we're going to have to identify the existing hardware in use and find the ko's or source for those devices. Then we can start thinking about which devices we would want support for that arent currently supported (4G LTE modems for example).

This thread is really disorganized. It would be great if we could start a wishlist (roadmap) and give it some structure. Then we can start doing the work of actually making it all happen.

I am ready and willing to spend some money on professional devs if required, though I would like to see how far the community can take this before an investment like that is required.

Your work is great, please keep on.

Unfortunately, I am of no help as I am not a dev myself. But I will try to help with my limited knowledge. Being that said, It does seem that this is the poweroff sequence as you say ( I do not get the gps thing, though).

Have you thought about setting the modification dates to its original dates? Or, the size of the apk to the original size?

Probably, this is just useless on an apk, but I remember reading something on that direction on Finless thread, worth trying.

Another thing, what happens if you just unpack apk, and resign it, without any mod, does it work?

Is there any log or debugging option that can bring any info on what's the actual problem that causes bootloop ?

Have you checked if there's any call to anything on the bootloader that checks signature of the apk, or anything of the kind?

I like how it has it built right into the replacement dash. I ordered it already and will report back with how it works out. I am pretty new at all this so will be digging into this thread for sure.

I was looking at some without DVD before as I didnt require it, but this just seems to be exactly what I need. I also looked at the Ca-Fi dashlinq4 but didnt like the 4gb storage. A higher resolution screen is not necessarily important to me, hope I dont regret it later on though as this one is 800x480.

I also ordered their bluetooth OBD reader (hopefully it can work with this thing, but I am not sure where the bluetooth OBDs lie as of now), and a backup camera.

I have posted on Freaktab as well. Someone must have come across this before. If I do any mod to the apks (there are a few of them - settings systemui framework MTC manager)

It bootloops.

If I unsign them - it bootloops

if I resign them with debug certifictate - it bootloops

The bottom line is we must hack this to make some great changes. The unit will stay in standby as long as we want if we can change this code (I have tested this in recovery mode - it stays on as long as you want it to with acc off)

We can fix the brightness bug.

We can force loud to stay on

Yeah I can play with the MTCRadio.apk and modifiy - it is signed with a different certificate but dont think cert is even checked if I remove it.

So I can mod radio code as much as I like.

If I just resign the framework-ras.apk or MTCManager.apk - no decompile - it bootloops. So it is checking somewhere
