[MTCB Android Head Units Q&A] typos1:
Yeah, I know, welcome to the thread ! - Its full of idiots (though not everyone I must stress) not bothering to read the first page or to use the thread search or even google. Did you read the post asking if apks could be installed on iphones ? !! I m mean really. The forum is for developers, hence the name, but we get all sorts of idiots on here. A lot of whom cant even use Google search, let alone Android. And they want to be spoon fed basic stuff and have everything done for them, they even expect you to search this thread to answer their questions rather than do it themselves, they are so lazy/stupid (delete as appropriate).

Its the same as the RK3066s - Android firmware is interchageable, as long as you have the same processor.

Read the first page !!! The Android side is interchangeable !!!!!!!!!!

On the about screen on your unit it says "JY" in the MCU section, note the "JY" in the header on the first page ? Read down a bit further and again he mentions "JY" versions. You think pakidermo put them there for a laugh ? ! :)

It also specifically says that for root on KK 4.4.2 or 4.4.4 you need to install a pre-rooted image.

Is there a way to increase the mic gain? It is very low in both internal and external microphones.

It works very well if I'm speaking right into the microphone itself, but it speaking normally in about 50cm away from it - the other side of the call hear me very low.

(I searched the thread and found someone else with the same question, but no answers)

p.s.

I have a "Sound Recorder" app (built-in from the ROM) that can be used to very easily see how low the mic is recording when not talking right into it. The gain is simply almost zero!

I want to try the latest Malaysk's ROM.

I see here that the latest version is from April 25, 2015, but it is for 800X480 and I have 1024X600.

The latest 1024X600 version is only from April 6, 2015 ....

Is there a 1024X600 version of the newest April 25 build ?

Tomorrow I'll try to disassemble the device to find out the exact model of the card. Is it disassembly easy work and is there anything specific that I need to know. Do as I see from the attached photo card is plug& play isn't it? I google it for such a card, but without much success. Would I showed me where I can buy one for my UNIT(Huifei_KGL). The seller that I bought the device is not interested to help me. I wrote to him many times -without response.

Again thanks for your time.

my Weather app does not work though.. anyway to fix it?
[MTCB Android Head Units Q&A] Krisjan89:
have you tried using some of the apps on play store to adjust gain? just search for "mic gain" .
[MTCB Android Head Units Q&A] agentdr8:
Spirit doesn't work with these tuner chips. AFAIK, there are no other apps that can control the tuner.

There are alternatives though...you can use a streaming app for radio (TuneIn, etc) or use a usb SDR with associated app(s). Neither of which will get you the integrated experience as the built-in tuner will though.
[MTCB Android Head Units Q&A] Enc0der:
I did, none of the apps that I found actually work on the system level (or at all..), they are simply a "sound recorder" app that amplify the recordings..

I think that a real mic gain adjustment must be done in the kernel/rom level, I have a custom kernel for my phone (lg g2) that does that.

Hi,

I have a problem with PowerAmp autostart. I have coudu's ROM and I believe it is related to it.

PowerAmp automatically starts everytime my unit boots. And it causes problems. If I have PowerAmp in front when the radio shuts down, it will stop playback on the next boot. If I have radio as the latest active application, on the next boot both radio and PowerAmp will start playing. If there is another application running at shutdown, on the next boot PowerAmp will start.

The desired behavior is that either PowerAmp or Radio (and only one of them) will start playing at the next boot depending on the last active source. I believed it could be also related to XposedMTC but disabling it didn't change anything.

Am I the only one having this problem with coudu's ROM?

Can-bus

Hi,

I just got my 4.4.4 ford focus unit with can-bus. Everything is working except the backlight for the buttons. Now I noticed that can-bus in the factory menu is not on. There are 3 options with Ford Focus. But if I choose one of those my steering control is not working.

Any ideas ???

I just opened the front of mine, pushed the existing ant (just a shielded coax that was striped at the end) through a hole in the side. Soldered a thin 8" wire to the center conductor. and taped it over the top front (out of sight). Gained 8 to 12 db of signal. Didn't even have to take it out of the car.

Edit: added picture of original location, a little blurry but was at the front left of mine. Put it through a existing hole just above where it solders to the board.

For your next rom, can you please make an option to disable the brightness slider on the notfication shade? It is pointless for me and always in my face.

Also I mentioned before, notifications that have actions (Like say spotify track control) display a very light colored icon on a white background, very hard to read.

How do i change the global sound ?

Thanks :)
[MTCB Android Head Units Q&A] agentdr8:
The MTCManager saves whatever the last foreground app is on shutdown, and restores it on the next boot. Poweramp shouldn't auto-run at boot unless you have it set to in the install-rcovery.sh script, or possible via some other boot manager.

This does not work for my JY with coudu's rom, Loud is off after a restart.

any idea why?

This does not work for me as well....

I have PlayerPro (newest version, v3.1) set as my default player and works great with my "media" hard button, but the next/prev buttons (from the hard buttons / the steering wheel) does nothing.

Other players (PowerAMP, JetAudio..) works with no problems.

I have CANBUS (VW), and the steering wheel remapping from the settings page does nothing in my unit.

I have a htc one m8 and the funny thing is when i instaled the new original unrooted jy version,my contacts showed corectly. But when it didnt format system and cache becouse of the oem partition being too small my contact names stoped showing. I will install the fixed version tomorow and post back if the contacts show again.
[MTCB Android Head Units Q&A] agentdr8:
Try not enabling that option in XMTC and just enable Loud in the amp/eq settings screen. Then reboot and see if the setting is persistent. I haven't seen a rom after 4.2 where this override was necessary.

Hmm, I wonder if the swc send something different when done via canbus. I'll see what I can find.

---------- Post added at 11:47 AM ---------- Previous post was at 11:44 AM ----------

I don't see why not, as long as the sound is routed over the usb connection. I know there were links posted earlier in this thread that had to do with external HD radio tuners that work over usb with custom apps.

The biggest issue you'll run into with these types of solutions is overlapping audio from MTC-based apps (radio, music, video, ipod, aux) and these apps outputting audio. Not a huge problem, just something to be aware of.
[MTCB Android Head Units Q&A] Enc0der:
thanks, I'll try.

I'm not sure this is the reason it's not working, because:

a. The hard buttons on the unit doesn't work as well

b. They does work on other players (poweramp..), both hard buttons AND swc.

So that's something that is specific to PlayerPro IMO...
[MTCB Android Head Units Q&A] echudoba:
Still fighting my hang on boot animation about 1 in 10 boots now. Still would like to know if anyone else with a rk3188 sees this. There has to be new one's coming on line every day now.

I also want to share something I learned because of all the times i need to reboot. Holding the on/off button until the screen disappears will restart the hu (about 8 seconds). But holding the on/off button for about 13 seconds until you hear three beeps will put it into recovery (without using the reset button). This may be a easier way to get into recovery. It works anytime for mine anyway.
[MTCB Android Head Units Q&A] agentdr8:
Maybe the PlayerPro intents have changed. I'll take a look at the latest package.

EDIT: Are you using the PlayerPro trial by any chance? It has a different package name than the paid version, so the intents are also different.

[MTCB Android Head Units Q&A] J0sh_FG:
You're right. It's made by NXP Semiconductors.

From : http://en.wikipedia.org/wiki/NXP_Semiconductors

NXP Semiconductors is a semiconductor manufacturer. It is one of the worldwide top 20 semiconductor sales leaders and was founded in 1953, when the Philips Board started a semiconductor operation with manufacturing and development in Nijmegen, Netherlands. Formerly known as Philips Semiconductors, the company was sold by Philips to a consortium of private equity investors in 2006. The new name, NXP, stood for the consumer's "next experience", according to then-CEO Frans van Houten. On August 6, 2010, NXP completed its IPO, with shares trading on NASDAQ under the ticker symbol NXPI. On 23 December 2013 NXP Semiconductors is a component of the NASDAQ 100.​

You can continue to read the historical line in that link.

Even knowing that software could be switchable between these similar boards I still prefer the KGL product because of the components it implements.

Here's my theory: Compatible software (thanks to the Rockchip). Different hardware. Klyde manufactures his own unit, KGL makes HuiFei. The rest are just distributors/resellers/vendors ...who rename these two units.

Cheers
[MTCB Android Head Units Q&A] typos1:
Like I said it was only a quick google, I was on my way out.

But that explains the Phillips link, possibly its a Phillips "designed" chip, possibly not.

Personally, I dont consider it a totally different unit just cos a few internal components are different - a BMW 520d and a BMW 525d are still both BMW 5 series, one just has an extra turbo - and I cant say which of these units is better or not really based on what boils down to a couple of different radio chips, (both it turns out from the same manufacturer), a couple of different GPS chips and some modded software. Everything else hardware wise seems the same.

KGL wouldnt have an option in the menu for a radio chip it doesnt use, so the software must be provided by someone else or the units you say arent HuiFei (cos of the GPS and radio chips) are HuiFei just slightly different models - KGL make WinCE units as well, so its perfectly possible that they make variations of their Android units.

Most people selling these claim to have a factory in China, they show pics and photos, maybe theyre making it up to give the impression they are bigger than they are ?

Or maybe there are a lot of very small companies that buy the components, assemble them and sell them - I m sure someone on the AN21-U thread or earlier in this thread has suggested that.

I do think youre getting far too hung up on Klyde and HuiFei names - there are loads of other companies and unless I d been to China and checked some out, I wouldnt like to say exactly whats what and who makes what for who etc

I dont think I have a theory about this really, but I do think they should all be grouped in this thread from what I ve seen and read.

:)
[MTCB Android Head Units Q&A] Orisai:
I'm more inclined to believe that there are multiple small factories making these units and the software to run them. That would justify the poor software implementation of non-Android hardware compared to a bigger, well-established company like Innotrends (the makers of the Ca-Fi Dashlinq4 headunits).

Do you perhaps have a picture of how the antenna socket is connected, and maybe where the radio chip is located?

It will save me opening my unit.

I have found that if I amplify the radio volume, I can hear radio static (it sounds more like AM radio static on FM), it goes away when I click the "Search" button, and comes back when it stops, or a search manually.

This makes me thing either the wrong driver/interface is loaded for the radio - or maybe the antenna socket is loose?

you need this app to operate it on android:

a super small usb module that can do FM and DAB tuning (and watch television as a bonus) for just about 15 euro

As far as i read the reviews, this should be working better than the build-in fm-module (at least better reception)
