Hi,

I am trying several USB cameras at hand to make work with my unit. However, none of them could produce an image.

I installed an app which shows connected devices and according to it all of my USB webcams are identified as a front camera.

However no image...

What may be the problem ?

I have read every post on this thread discussing USB cameras. Below there is an information but I didn't get where that settings is ...

To all friends who have problem with fm reception. Check to see if your car has already an antenna amplifier. My car has and because KLD doesn't give power through the connector but with a blue wire that is separate from the connector, it was like I had no antenna. I cut the power wire of my antenna from car's connector and connected to that blue wire and now I have perfect am and fm reception. Lucky I have the service manual of my car and I saw which wire to cut

Its not the radio app that does it, its the MTCCAN Bus app and it works on VWs, mostly, but not all models - it depends on year and spec, try changing the CAN Bus settings in factory settings.

Thanks, but its a known fact thats been mentioned many, many times in this thread.

None of the units, Klyde included, put any power at all into the antenna, in fact after market head units in general dont do this at all, Android or not.

The blue wire is for a powered antenna and again, this is standard after market head unit stuff - they all have a blue wire for a powered antenna and a blue wire for an amp trigger.

What people normally do is buy a power injector for their OEM and power it using the blue powered antenna wire, the power injector also contains static filters so you get no interference, I m surprised your reception is perfect.
[MTCB Android Head Units Q&A] jimsiv:
To me the power injector didn't work that's why I mentioned that.

My antenna seems to pick up all the stations, FM is crisp without anything additional other than my car antenna plug.

However there is one AM station that i listen to which gets a high pitched noise on it. Very annoying as this is the only station i want to listen to.

Would this provide any benefit?

Somebody else from this forum reported that some Logitch and Microsoft camera models, works just perfect. If there is no preview on screen when you attach the camera, then that camera is not supported. My issue was related with recording, not with previewing.

KGL-7006, good or a bad choice?

it appears that the only universal model with 1024x600 right now is the 7006 model if I look in the Kaigele pages on Alibaba.

I also read here in 3 posts about this model and they are not positive. Anyone successfully have this model running without any major issues?

Is HuiFei still the brand to buy for easy root'ing and customization or have something else become better?

I've just ordered the JY-8813-7. :)

http://www.aliexpress.com/item/7-In...Android-4-4-VW-RADIO-WIFI-3G/32250135728.html

I was tried of waiting for the Quad Core version, especially because the boot time was the same and because I wanted this specific model for its hard-buttons layout.

So you should know - Murphy is coming and I bet Quad Core units will come out VERY soon with LOWER price than current Dual Core units :laugh: :eek: LOL

Does the ROM in this link is the original 4.4.4 ROM of this (JY) unit?

http://huifei.fs-fileserver.de/content/firmware/JY 4.4.4/

If it's not the original, is it possible to make a complete backup of the original ROM from the recovery before flashing a new one? Can I keep it in the external SD card without it being formatted when flashing a new rom?

For the coudu's roms, I see that he have a JY-based version as well:

http://huifei.fs-fileserver.de/content/firmware/coudu's_roms/4.4.4/1024x600/

Is the difference between these versions is only by the design of the launcher and MTC apps, or is there other difference?

I see that the JY version is 4.2 while the KGL/KLD also have 4.2.1 ....

thanks
[MTCB Android Head Units Q&A] typos1:
Yep, someone has decoded it, all it takes is to use the thread search box to find the posts. :)

The 1024x600 resolution is available on all screen sizes apart from 6.2". ALL KGL models are the same, the only differences are the screen sizes/resolutions and the plastic fronts, there is a quad core version available now and even that is exactly the same apart from the CPU card. If you read the first page you will find out that HuiFei IS NO "the only brand" there are about 8 brands of this type of head unit and they all root the same way and have interchangeable Android software.

No, Google it.

What problems were you having with reception and TA ?

---------- Post added at 12:18 PM ---------- Previous post was at 12:10 PM ----------

There are copies of the original 4.4.4 JY ROM and rooted versions posted within the thread, around the last 4 months I d say, from memory. Some quad core versions are out already.

Murphy ? ?
[MTCB Android Head Units Q&A] Enc0der:
Not from JY as far as I know so none of them have the buttons layout I am looking for. Also, none of them are specific for VW yet.

[MTCB Android Head Units Q&A] typos1:
Its just a question of waiting, I wouldnt buy a dual core now personally.

Ah, if you d said "Murphy's Law" or "Sod's Law" I d have known what youd meant. :)
[MTCB Android Head Units Q&A] Enc0der:
I would prefer quad core as well, but I need something soon and the difference is not big enough for me (the dual core units work fine as far as I see on reviews etc') - also it will probably be more expensive...

what about my question regarding coudu's roms?

http://huifei.fs-fileserver.de/content/firmware/coudu's_roms/4.4.4/1024x600/

Is the difference between these versions is only by the design of the launcher and MTC apps, or is there other differences?

I see that the JY version is 4.2 while the KGL/KLD also have 4.2.1 .... why? (4.2 / 4.2.2 is the ROM's version, not android's version - they are all Android 4.4.4)

Wavesink is rubbish. DAB USB receivers are rubbish too.

I will also try. But at the end of the week only

I have this one: http://www.conrad.fr/ce/fr/product/...kGdaoxJe8svnVwpsqPOHAme_KDkDsRF1idRoC8BDw_wcB

You can defenetly find better than mine, but for the 2-3 hours/year that i use the radio it is more than enough

I also had problems with my canbus decoder for my mazda 3. You have to tell them to send you the new version (the one that is deliverd with the unit is for the mk2). I was lucky because when i bought it i was in a business trip in Shenzhen and i was able to change it directly at their office...
[MTCB Android Head Units Q&A] typos1:
There is no "4.2.1" version on these head units.

I ve only ever seen 4.4.4 JY versions, very similar to the KYD versions. There are 4.2.2, 4.4.2 and 4.4.4 versions of KGL, KLD around as well, I would try them all and use the one you like best.

The differences are the design of launcher and some apps. Just google it and you will see pictures, or search the thread.

So far I haven't been able to get it to work with the music app, only Google play music. Either that or my ears aren't sensitive enough lol.

Maybe someone will just mod the built in eq
[MTCB Android Head Units Q&A] J0sh_FG:
Well..all of this take us to the first point: we don't know if the HuiFei audio chip is made by Toshiba.

I said the Klyde uses that STMicrolectronics one because they actually give us the model number of a ST chip in their specs. This chip goes from 4x25w to 4x42w. We can't extrapolate that HuiFei units uses this chip too just because they claim their amplifier is 4x45W.

Erisin is now selling a new model that has more chances to be a identical HuiFei radio. All of them appeared after the HuiFei already was in the market. This gives some clues too.

There is no txt file to change the codes, all is on the java source code.

I will do modifications soon to make it customizable on future updates.
[MTCB Android Head Units Q&A] kaween:
... no no. When it works, it's clear as day.

Change room size to some over-the-top value, Change "Wet" signal to 50% and you WILL notice it working. :D (IF it works, of course. Don't have a Huifei, can't test it myself).

As for "modding the EQ" .... slim chance. If the audio chip only provides a 3-freq EQ (which is hardwarebased !) you can't really change it to a 7 or 15 channel EQ at will of course. :)

That's where ViperFX steps in.

How does the Huifei react on Poweramps' EQ ? That certainly should work.

[MENTION=1436975]R4D3N[/MENTION] : yes, basically. That's how it reacts on my S150. Everything is altered by the Viper settings, except Radio. (and probably dvd, never tested that)
[MTCB Android Head Units Q&A] kwalsh24:
shall give iit a try, I know I can hear a difference on gpm. just didn't think i heard a difference with the built in app. to be hhonest the radio app doesn't need anything other than what the stock eq does as I find that the stations I listen to already as they seem to have way more base than what anything else I use app wise in the radio.

now to just get the built in radio & music player app updated to the modified ones.

Good luck with your unit ! The Huifei's look marvelous, I hope it will serve you long and well.
[MTCB Android Head Units Q&A] typos1:
I ve seen claims of anything from 4x40W, 4x45W and 4x50W and I suspect that that theyre all 4x42W STMicro Electronics in reality.

Personally, I m not taking the claims of output as exact (there are often discrepancies in Chinese listings - anyone know what "hardward processing" is ? ! or a "TV turner" ? ! Or maybe "maps solution 800x480" ! ? Shenzen Burgeon has a listing for one of these and it states "FM Transmitter" and "Mobile phone" in the specs, neither of which the unit has), I suspect its just human error and some things have got exaggerated or rounded up when the specs were typed out in Chinglish.

But cant get any proof until someone opens one up and has a look.

I d always thought that Sharing Digital was selling HuiFei units, but, though the specs and screenshots look the same, theres no mention of the name "HuiFei", Shenzen Burgeon mentions the brand as "Eastcome".

I also think all these units with Rockchip processors are all pretty closely related, even if some of the built in apps and a couple of the components (GPS chip, Audio chip) are different . This thread should cover them all and not specifically ones with "HuiFei" on them. The companies probably buy Rockchip SOCs and assemble them the way they think fit, adding or removing features, modding a little etc. I dont really think theres any point it ONLY buying HuiFei branded ones and rejecting others either.

Maybe an app developer can come up with something for the MCU that can identify the components, like the many apps that can do that for the android system ?
[MTCB Android Head Units Q&A] R4D3N:
Thank you.

I had a navigation unit previously, ES1146B (WinCe 6.0) from Erisin which was a very good unit and then ES7212A (which is WinCe 6.0 + Android 4.0.4) which again runs smooth and no problems at all, but I think that this model, which seems in fact that it is a HuiFei unit works better, faster, it has an OEMisch look and above all, I chosed this for the capacitive screen and the fact that is full Android.

Nice review. The KGL network in the WIFI settings proves it's a HuiFei unit.

[MTCB Android Head Units Q&A] kwalsh24:
hmm yeah, the viper app onky works with google play music, as there is zero change with the sound on the stock music player on my unit, there is tho with gpm. the sound isn't horrible, just. not as good a viper, can live with it tho!
[MTCB Android Head Units Q&A] typos1:
This one sold by ShenZen Burgeon is also a KGL unit, does it mean its HuiFei ? There is no mention of HuiFei anywhere :

http://www.aliexpress.com/item/6-2-...-Car-DVD-Player-Capacitive-3G/1788028428.html

It has "KGL" as a wifi address, but its listed as an "Eastcone" and the output is listed as 4x41W.

I ve spent so much time comparing so many listings and specs my head hurts .

Having dealt with several Chinese suppliers of Android TV boxes, I know for sure that lots of different companies sell essentially the same thing, often looking identical, with identical hardware, sometimes packaged in a different casing with identical hardware, basically lots of slightly different variations of the same SOC and I m pretty certain its the same with these units, I dont think we should get hung up on the brand "HuiFei" which I think has just been made up by one company (Kai Ge Le) to market their version. Generally on xda and similar forums, threads on Chinese units are sorted by processor type, so I think we should think more on those terms and not turn away people who virtually the same product but with one or two slightly different peripherals and the odd software mod. Especially as nothing appears confirmed as yet.
[MTCB Android Head Units Q&A] J0sh_FG:
Please........ just look at the MCU version:

There's almost enough info in every advert to determinate which one is. Just look at the details, there's the difference.

I think u have misunderstood my point in all of this. My Bmw E46 HuiFei unit isn't from Kai Ge Le Electronics neither. It's from a UK/ Canadian distributor who renames it too. But I know for sure it's the same product.

We don't have to buy this Unit from Kai Ge Le. But knowing the changes in hardware between the Klyde and the HuiFei, I choose the last one. That's all. And as far as I know this thread started with a HuiFei Unit.

Cheers
[MTCB Android Head Units Q&A] typos1:
I m fully aware of the MCU version - I think you have misunderstood my last post - go back and read it.

Shenzen Burgeon is selling a HuiFei one (its HuiFei according to your criteria) but its has a 4X41W amp , not 4X45W, so it cant be a HuiFei, by your criteria, but it is a HuiFei also by your criteria !

We shouldnt get hung up on this "HuiFei" bit, its all marketing, these are all broadly speaking the same products with some small mods, the OP probably didnt realise that these were available from half the companies in China, over on the AN21-U thread, there are multiple sellers selling the same basic MStar processor units with slight variations and different fronts. If its not HuiFei, it is incorrect to call it a "clone", its a variation of the same thing. We cant have a different thread for every slightly different variant, that would be silly, thread should really be for "Rockchip RK3066 Android Headunits"
[MTCB Android Head Units Q&A] J0sh_FG:
The 4x45W amp spec is not my only criteria when it comes to differentiate a HuiFei from a Klyde, you know this, or should have by this time. So...don't make easy conclusions. Did you look at the User Interface? The launcher they are using? Doesn't really say anything to you?

You can pass 4x41,4x45, 4x50W as errors. But not in conjunction with a different launcher, different radio receiver, different gps receiver, (leaving the Amplifier alone..). Even different front fascia with differen buttons and a different back plate in some models (my e46 for instance).

Ok, sorry for doing Marketing for HuiFei. But blame Pakidermo for starting a thread with this name. Tell them to change the TOPIC to " 2DIN pure Android bla bla bla UNBRANDED Head unit " because seems like we don't know anything about the factory. It's a mistery.

My apologies. From this time on I will refer to Huifei unit as KGL.

Cheers
[MTCB Android Head Units Q&A] typos1:
Again, read my post, no doubt Pakidermo didnt realise the profusion of units, the AN-12U thread started as that but there are many different people selling slightly different versions that are not all called AN21-U.

No-one really knows for sure yet what all the internals are for the different units, but they should be grouped by processor type, we also dont have any confirmation that one MCU type, or one GPS chip type or one audio chip type is better or worse than another as yet.

I did not mean you were marketing for HuiFei, I meant that the name "HuiFei" is just brtanding b y someome, maybe KGL, maybe someone unknown and not to get too hung up on it.

There are choices of launcher on many of these units, you cant just go by that.

The is not just Kai Ge Le, theres Sharing Digital, ShenZen Burgeon, Navall, AutoGPS, and countless others, we dont know which are the factory or factories which are re-sellers (well, AutoGPS is a UK based importer, so theyre clearly just re-sellers).

Pakidermo was branded HuiFei, so its not "unbranded", I m saying the brand is not that important and they should be classified by processor type, ie RK3066.
[MTCB Android Head Units Q&A] J0sh_FG:
About the GPS and Radio receiver I did some research in the past weeks looking for datasheets, collecting much info in the net and talked with several distributors that sells this KGL product and other types of radios. So I have learned enough things about their hardware to determinate the best choice (for me, for my car..and taking in consider the radio reception in my country).

If I see a thread where there's a listing of specs for a radio called HuiFei and then I see a product that matches all (or almost all ), sorry but I call it by this name again. If time after, another one appears and there's several changes on it....including external looks, MCU version, User Interface (Talking about the DEFAULT LAUNCHER they show) and the previosly mentioned hardware differences....sorry but I dont call it HuiFei. Could be software compatible, and could have many more similarities but it's not the product that started the thread.

I understand your concerns, but you should consider mines too.

Actually 2 of the vendors that u named there are the same and they told me about this KLYDE manufacturer when I came to them with info about a slighlty different HuiFei.

Dunno, must be how coudu numbered them, the higher the number the newer the version - he just slightly modded them (re parted and pre rooted mainly) as soon as we got hold of them.

But its not that important if theyre all 4.4.4, just try them when you get your unit and see which you prefer.

If you search all coudu's posts you ll see the change log. There are also some versions in the thread that arent on the server - coudu hasnt posted for ages and the latest versions have been pre-rooted by DSA, cant remember if you he reparted them as well, check his posts over the last month to see.
