[MTCB Android Head Units Q&A] ptclabs:
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.
[MTCB Android Head Units Q&A] Reptile-X:
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 :)
[MTCB Android Head Units Q&A] genius312:
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
[MTCB Android Head Units Q&A] agentdr8:
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 :D
[MTCB Android Head Units Q&A] genius312:
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. ..
[MTCB Android Head Units Q&A] Reptile-X:
You are right, I too find the automatic headlights little to jumpy. It might even cause lag when the HU tries to keep up with brightness adjustment while driving a tunnel in and out. Automatic headlights suppose to be intelligent with tunnels and garages but it doesn’t work like that.

I think GPS option would be the best, I am not sure if other users have their GPS on all the time, besides together with java it is a lot better when it calculates automatically.

You are doing a great job to get this units integrated with the car :good:

Headrest Monitor

Hi again ;

I do not like to double post but i m looking for an answer why the Huifei works with headrest monitors only on dvd but not with other 3rd party video players?

Whether it is related with MCU or software/hardware ? And if there is a solution the problem?

Thanks in advance
[MTCB Android Head Units Q&A] blankers:
It's already been done. Check out the radio app on the first page by 1-2-hak. I've been using it for a while and it works great....
[MTCB Android Head Units Q&A] typos1:
The Roadmaters do seem very good and the HuiFeis do have some bugs.

But Roadmaster's range is quite limited though and they are more expensive, plus I think their launchers look cheap (although they could be changed quite easily).

Dont forget the Klydes though, they seem to have less problems than the HuiFeis, plus the best launchers and widgets (in my opinion anyway).

I think ptclabs has got a GS unit and installed HuiFei software and reports that the combo is better than the HuiFei units, so thats another option.

The unit in the link you posted is Android 4.4 and quadcore (no processor manufacturer named, maybe it uses Rockchip's RK3188 ?), so isnt related to the 4.2.2/dual core units in this thread.
[MTCB Android Head Units Q&A] 1-2-Hak:
Mines just blue color but I think pakidermo5000 did one like that.

Id like to see 4.4 on this unit. definitely be interesting
[MTCB Android Head Units Q&A] typos1:
Normally cheaper Chinese stuff doesnt get version upgrades, but I get the feeling theses units might.
[MTCB Android Head Units Q&A] kwalsh24:
True, guess it depends on the manufacturer and what they decide to do. Could also lead into a sales gimic, get 4.4 + 1024x600 screens

It has the right kernel for it already on mine with 1.91 gs. I guess I could get brave one day and flash the system and see if it restarts. I have had it downloaded on my desktop staring at me.

[MTCB Android Head Units Q&A] agentdr8:
I think MTCSync is an older launcher. It uses the line-in audio source, so maybe it was like their version of Ford SYNC?

The other app shows additional info about the car via canbus. TPMS, fuel level, etc. Don't know if it actually works though, as I don't have canbus.

I need your help in choosing the universal radio.

Is there anyone who can answer my question.

How these radios look compared to parrot asteroid smart ?

I know that Parrot has an old android, but I'm talking about sound quality.

Which of the universal models would you recommend ?

I was thinking about this model:

The odds that someone owns both radios.......kinda slim.

Therefore, probably going to be a tough question to answer.
[MTCB Android Head Units Q&A] Dareksa:
I guess so, but maybe someone saw Parrot in action and has some comparison with Huifei.
[MTCB Android Head Units Q&A] nexgen10:
FWIW, I've never heard a really good review of the Parrot radio. The general feeling is they are over priced and under perform.

[MTCB Android Head Units Q&A] 1-2-Hak:
Mine is a bit weird - Torque had a Bluetooth device detected but it didnt work so i removed it and tried via bluetooth. that didnt work either. Nothing was prompting for Pin.

I have sucessfully done screen mirroring with a galaxy s4 and an Ipad 4
[MTCB Android Head Units Q&A] jayroudy:
How did you mirror. I was never asked for a pin in torque and the initial connection took an easy 1 to 2 mins
[MTCB Android Head Units Q&A] 1-2-Hak:
I think its my odb - its pretty old but it does work on the phone but asks for a pin

Screen mirroring

For Iphone/Ipad - Start the airpin application - Then use Airplay

For Android Go to Settings - Display - Wireless Display to on. Then use Screen mirroring

There is something funky about the brighness setting on this rom.

When you change the brightness it changes it for when the headlights are on. That part is ok. But when you turn them off the brightness stays dark.

That needs to be fixed - Keylo?

Another issue is the Loud doesnt stay checked on a reboot

Since the internal mic is rubbish, i ordered an external mic. From reading this thread I learned that a Parrot microphone works the best. So I ordered it and installed it.

Now the sound on the other end is louder than before and somewhat more clear, but still isn't loud enough and has some static in the background.

Anyone else experience this? Does static mean that I have a bad ground ??
[MTCB Android Head Units Q&A] Reptile-X:
In most cases yes, but do you have it when the engine is off? Or does it get louder when you rev the engine?

in the market as well!

how did things go for you? I am in the market right now for one. I saw the Xtrons on sale right now but like to get some feedback.

My must have are:

Well for the most part I like the mirroring capability. In fact I think about just require audio indash to have hdmi input and just hook chromecast into it.

Xtrons have hdmi but it look to be external, I am looking for something internal. Also with these indash have touch screen, once sync with cell phone via chromecast/or mirror can you just touch and access full control via the screen from cell phone?

I mean to say using phone as the hardward and the brain while accessing control via indash for large screen real estate and safety of not fumbling with cell phone while driving. We all changes phone usually about every 2 years anyway so I don't put too much value on the indash tech as much as ability to use the cell phone as the brain. Anyone follow me? Thanks!

[MTCB Android Head Units Q&A] Reptile-X:
Inderdaad! :laugh:

We are going little off topic here since it is not related to the HU but here it goes.

I think it is still ground problem, but when it comes to ground problem there is always some investigation involved, first how thick is your ground wire to the radio and amplifier, did you check your ground wire/mesh wire from battery to chassis and grounding between the alternator and the chassis? Grounding in the amplifier could be a problem, there are lot factors which can cause ground loop sound.

Best way to check if there is a problem in your car or amplifier is to make a direct thick ground wire from the battery to the amplifier and make sure connections are good and keep the wire short as possible. Since the battery in a E46 is in the back that should be easy to test.

There are ground loop noise isolators on the market, some may work some not it is always gamble with ground loop noise:

Using 2.03? I put that on my GS and haven't run into it yet.

I'm wondering if it's the MTCFunkey app. It overlays the menu and home/apps buttons on the statusbar, which affects the SystemUI.

---------- Post added at 01:10 PM ---------- Previous post was at 12:59 PM ----------

Pioneer did exactly this with their AppRadio series of headunits. I've had two of them in the past, and they're not as useful as one would think. First off, using your phone as the brains for a car nav unit sucks, mostly because phones overheat when running HDMI out, GPS and navigation software for extended periods of time. Even with apps like Screen Standby, which reduce the screen brightness to zero, the phone will still get really hot and either stop charging, or start losing battery while still charging.

Secondly, there's always a need for an app to coordinate screen touches and app launching. For the AppRadios, this was done with Pioneer AppRadio app, which blocked what apps could be run over the mirroring. You could bypass this with apps such as ARLiberator or ARUnchained, but they too had their own limitations.

Hi guys I have a question, is there a way to change font colors on the HU without decomplying and such? Is there a Xposed module for this? I installed BusyBox, Xblast Tools but Xblast won’t let me change the colors in there, maybe it is not compatible with our HU.

This is how far I got with gravity box but I want app names red too:

[MTCB Android Head Units Q&A] Epiclectic:
Since nobody offered any advice, I gave up on indash. Instead of spending $300-$600 indash, I bought a Oneplus One phone and magnetic dash mount. Now I have a hi-def 5.5" screen with a 2.5ghz snapdragon, running custom built Cyanogenmod, in my car AND in my pocket. I only spend about 10 hours a week in my car, so upgrading from my S4 to this made more sense. The phone was $380, sold my S4 for $180, so with the mount I spent $220.

I mounted it where I can point an air vent at it, so it doesn't overheat running pandora + navigation + sigalert. Since I don't care about playing videos indash, this works great for me, and now I have a badass new phone everywhere I go, instead of an expensive toy in my car , which sits mostly empty all day. It bluetooths in audio, and I can still voice control it, so I am happy.

good luck!

kld on gs

Just tried the kld firmware on my gs.

Works good. Like the launcher a little better. Still have no buttons in multiuser.

The launcher is a little laggy because of more graphics I am guessing

Iheartradio is much more stable and no longer crashes.

Google voice typing seemed to understand me a little better, I have not tried a phone call yet

KLD has MUCH more bass had to turn it down, also the unit gets louder in volume now unlike the KGL software.

I will leave it for a few days and see how it goes.

funkey did not effect the launcher in anyway on this firmware. Looks like it is another launcher on top of the original RM rather than using the RM launcher like everyone else.So I am guessing many of the MTC files could be stripped to speed it up.

BT / WIFI worked fine

edit

Tried on my HF unit also

BT call voice reception (incoming) quality 1000% better, I may dislike the clock on the home screen, but for this reason it is not coming back off this unit until i find something better. buttons look cool though.

Bluetooth out-going 100% better also. no complaints either unit now.

It still lags a little on bluetooth audio music when trying to do 10 things at once. Other than that it works well. Well its is only a 1.6 what to expect right?

damn i wish i had the balls to try 4.4 on this thing

I just put 2 factories on the multi user issues. They are supposed to get back with me tomorrow. I am guessing neither of these two wrote the software though. Thats a problem..... Might have to place nice with RM to get to whoever wrote it.

Was talking with the people making the 4.4 with the external unit today, that thing looks pretty cool. They are sending a sample.
