As you may know if you read our sales terms, the first owner has a two-years garantee on HUIFEI products , but not the subsequent owners

It is not logical. The garantee is of the equipment or the owner.

hey guy ,

i already found that link and this is the unique link that you know and that i found . this link not say that radio is good.

but if you search in youtub you saw a lot them with radio work bad at this model and similar models.

i ask you a question where buy a good amplifier inline for mercedes (fakra conetion) and you didnt answer.

i knew that ww need amplifier but when you sell you dont tell us that mercedes need amplifier.

, ...... to other people saw that you sell equipment that don't work at radio or work very bad (with the amplifier and the blue wire is conect to 12v remote amp) if the car is driving. when car is stop works well what it found.

What are you trying to say? That the first page of this thread is wrong?
The fact that you are crossed that people don't answer your questions, has no meaning. This is an open forum, and if people don't want to or just can't help you they are free to not do so.
Or maybe your complaint belongs elsewhere.

You mis-understand him - that is his only post so he is obviously NOT talking about people on here not answering his questions, he is talking about the seller he got his unit from, this is obvious if you read it properly. He posted a conversation between him and the seller, he is obviously having problems with radio reception and his seller is not giving him a solution.

Try post number 3550 on the previous page, dcmouser had a similar problem and has sorted it, pm him if necessary

 

[markastor]

Hey when you were trying to modify the mtc manager app did you try to reinstall it as a user app or copy it to the system folder?

I have noticed it only works in the system folder. Without or if it is in the user folder it you lose touch screen also, have to use a mouse. I am still searching the code to see what is before ir.keydown. There has to be something in this code as without the file I have a lock button, and and home, nothing else. It changes the lock button into a button that can call the mute somewheres in here. I have deleted all other mcu stuff except for one app.

I will see if it controls anything or just has settings in it after deleting the other file, I think the other app just does audio though.

Looks like something around line 1360, or maybe 2238 in the server file to me, but i am no expert.

I stand corrected. But it was not very obvious.
Also I would like to put on record that I wasn't trying to bash the man for bad english!

Fair enough, but I disagree - it WAS obvious, it took me all of 15 seconds to work out

Reading your post once more again, mcu.cfg being aborted shouldn't really be the problem.
I have the same message when upgrading, because normally there is no mcu.cfg.
It's only there, if you do an export of the factory settings.
The real issue is that no mcu.img is found.

Finally I worked out how to update my MCU guys, like I said before my HU wouldn’t update from GPS card slot only way to update the FW was putting the update.img with mcu.img in the internal /mcn/sdcard but the “not found” error for mcu.img got me thinking since most guys here update from GPS card slot, I placed a system.img and mcu.img in the internal sdcard root and only one mcu.img in to GPS card slot to see if it grabbed it from there and that worked, probably somehow my unit is checking the MCU update in gps card slot and the FW update in the internal flash, maybe it will upgrade from anywhere now since the mcu is upgraded from 1.70 to 1.77
I am not going to try that after couple days of struggling with this crap

Running 2.02 FW and 1.77 MCU now:

Thanks to those who were trying help me out, I really appreciate it

You can't install the MTCManager. apk as a user app; it's a system app that uses the sharedUid of "system" (i.e. root).

There's a code section that deals with the serial communication between the MCU and the Manager app. This is how it determines what physical button relates to which android keycode. This is also why some MCU firmwares tend to mess up button assignments.

What are you trying to achieve with multi-user? Different button assignments per-user?

HuiFei - 2 DIN Pure Android 4.2.2 A9 Dual Core Car Stereo Radio Head Unit

what difference is there in 2.02 compared to 1.99

I can' tell you the differences... I upgraded from 1.77 directly to 2.02

secondly i have the paid version of poweramp, how do you get the steering controls to work with poweramp, for next\previous track, the defualt apps work fine.

I've installed xposed framework with xposedMTC, so I can select, which apps are toggled with the MODE-Switch on the HU / R/T-Switch on the steering wheel - next/previous track works just fine.

I'm really happy that you finally got it managed to upgrade your HU after such a long time of tial, errors and frustration!
In case you will do a further upgade in the future, please let us know whether the standard GPS-slot procedure now works - just to find out and make us happy whether the assumption regarding special behaviour of V1.70 was correct.
But for the time being: Have fun now with your HU!

Can you please check whether your TVbox still works w/ 2.02 FW / 1.77 MCU?
Thanks a lot!

Thanks ProfessorKnox, I have patience with most things, but after two days I was getting frustrated indeed. I will post information if further updates works or not from GPS slot

TV Box is working like before with 2.02 FW and 1.77 MCU no problems there. :good:

Just came back from the car, I was tweaking XposedMTC and Gravity Box.
@agentdr8, thanks for your efforts and time you put into XposedMTC, I couldn’t test it widely before, because of my FW issues.

No problem. I like giving back to the XDA community as much as I can.

Working on the next release which should allow users to set their own radio presets, which will then get applied on every boot. This should get rid of the issue where the presets reset to the default values when you have to hit the reset button or the radio prefs don't get saved for some reason.

That would be great indeed, losing the stations every time is annoying, I would love to see if the dimming worked with the headlight switch (one of your future plans) Timed one works nicely, unfortunately here in the Netherlands is the time for sun set and rise changes a lot in couple days, could it maybe work with sun rise and set information from internet?

Not different assignments, just want them to work. Right now it reverts to default android mode in multi user with a lock screen and a home button only.

There has to be something stupid messed up in the code as most of this file is working. The touchscreen works, the calls to irkey intents work, just not the buttons.

Guessing that part has something like user 0 in it. Second user is user 10. Something has to be wrong somewhere.

Right now I am using tasker to "push" the buttons for me in multi user. As the physical buttons mainly do nothing.

Since user 10 can instal different apps, I think an easy way to handle the problem without getting into a elaborate remapper is have an app that repoints the physical buttons at the irkeydownintents again, since they are already working. I think they would more or less respond as normal programmatically pushing them rather than a script waiting for su. I do not even think you would have to do overrides as they do not seem to be mapped to anything.

Although long term goal is better control of the buttons.

As far as the goal for multi user. There are multiple people driving the car for work. My work is 99% communication need related. So being at the end of my electronic gadget chain and having everyone working for me at the end of one also is required. I can work, and do work from the beach many days. Long as I can return the mail and answer the phone I am good.

Right now who's ever phone enters the car, it connects to their bluetooth shooting off tasker to wifi tether. Since bluetooth is actually a mcu thing tasker on the radio cannot pick up the connect. Once wifi connects it runs an am switch-user XX automatically depending on the user. Bringing up their corporate gmail, and default like music player.

A lock screen was important to us because the nature of our job. We deal with DNA testing and have hipaa requirements and ISO requirement about privacy.

If we could find the offending line of code. I can ask them to change it.

We really need the compilable source for this one app to change everything that is wrong....

I can probably work the headlight switch dimming value into the next stable release. I'm guessing that you would want that value to override the timed value?

I also found a nice java library for calculating sunrise and sunset times based on GPS coordinates and a date. So maybe I'll have some time to add that in as well.

Whichever works would be great, GPS based or Headlight switch, I have automatic headlights and if that worked that would be great addition to the HU, overriding timed value would be best or use same value as timed one but with a option to choose between timed or headlight switch or GPS. I hope I don’t sound like I am demanding things by the way, just trying to think a long with you

Ok. .. after reading a lot of page on this thread and every where else. ..i see HuiFei seams to have a lot of little bugs!
But not roadmaster. ..
Is there any site i can order a good head unit ?
I see aliexpress.com is selling some roadmaster. . But really expensive !

There is a LOT of unit out there, and i see some new every days. ..
But i cannot see anywhere but here to get help choosing one !
I am very sick of my pioneer system with bultin gps (tomtom i think) that always freezes

Thank you for your help

No worries. I like the brainstorming aspect as well. I too have auto headlights, but they often will turn on when under overpasses for long periods of time, or when in parking garages. Those sort of situations I would think you wouldn't want the HU to dim since there's usually lots of indirect lighting still available outside. I'll have to think some more about the process flow and in which situations the timed values should take over vs. the headlight switch. GPS will be used to just set the start/end times of the dimming period (at user's discretion).

It would be nice if the auto headlights themselves could be synced with the sunrise/sunset. That would solve a lot of problems

Actually. .i just got an answer from a Chinese company.
Here is the link of the product : http://www.in-dash-cardvdplayer.com/sell-1422514-un3001-universal-pure-android-4-4-2-din-full-touch-screen-in-car-multimedia-system.html#.VBRMdYHD9Dt

And what she answered : "First of all, let me introduce our brand to you. We have our own brand"Newsmy", China top 10 car dvd brand. All our products are made by our factory. We are factory.
And we have our own technology, all our products are made by our own R&D technology.

Since you know: Roadmaster, Huifei, Klyde, i think you well know this industry in China. Are you a seller in Canada?
Actually a lot of factories in China dont have their own technology, they just use software company's solution. So it is very easy for them to produce product, they just need to assemble all the parts and became a product."

The write " support android 5.0" ... it can be fake or really good product. ..
