I think I made a boo boo, because I'm an idiot.

Upgraded to latest KLD mcu.img and [MENTION=3590033]Malaysk[/MENTION] 's latest rom, upgraded went fine. Then did a full restore from titanium backup, not thinking I probably shouldn't have restored google service files. I know get bombarded with alerts saying "Unfortunately, the process com.google.process.gapps has stopped." Is there a way I can grab all the com.google files from the update.img and copy them over? Or should I just reinstall the firmware and only restore apps + user data from titanium? Just wondering what the easier fix is.

Also Malaysk your new rom still has a problem with notification actions. If you use spotify for example, the pause / replay/ rewind actions are almost invisible because they are a very light grey on a white background. Would also love a setting to remove the brightness slider from the notification shade, it's not a setting I touch.

Of course they're not, it's just a friendly figure of speech. No need to be discourteous if you weren't aware of that and I'll try to be more "region-neutral" next time. We're all friends here. ;)

Yes, I know how to search the Play Store. There's quite a few GPS apps and my intent was to narrow down the list by soliciting opinions from others who may have already tried a few.

Oh! I did use that on a tablet before when it was Navfree. I'll add to the "give it a try" list. Currently checking out "Here" (Nokia) and it looks promising as well. :)

How to get into Bootloader

My unit is Huifei-KGL and it don't have front miniUSB. How to get into bootloader?
[MTCB Android Head Units Q&A] typos1:
I dont have a CAN Bus adapter, so cannot send you pictures.

You have to power the reverse camera using the other wires, look at the wiring diagram.

None of this is any different from any other car stereo, maybe you should find out how to do it from a car stereo forum in your own language ? It would be easier for you to understand.

Rudder is LHD/RHD. wheel3 is freewheeling control knob (a totally useless function), key and touch maps change the key and touch maps.

[MTCB Android Head Units Q&A] RonvH:
Hi all,

I have make the power button, and yes it's working.

It's the same layout as the photo here.

What is did...

Welding a cable to C84 as they told me.

And then a have make a (new) push power button, cable from the C84 and the other is the ground.

Put a sdcard into the radio with the update.img

Powering the system

Push and hold the reset and (new) power button

Release the reset button after 3sec, but still hold the (new) power button.

Release the (new) power button 5sec.

Then the radio starts in recovery/download mode.

Now you can select what you want to do.

Note:

Short press on the new power button = select

Long press on the new power button = enter

Thanks for the great help to make the power button.

My system is alive and working.

Ron :)
[MTCB Android Head Units Q&A] typos1:
In their defence its only a recent thing, no one reported these problems before the past month, not that it makes it any better. I m assuming that the manufacturers buy the SoMs in from either Rockchip or another comapny rather than make them themselves.

Leave the touch maps and keymaps they are nothing to do with your problems.

I cannot believe that there are no instructions for installing in aftermarket headunit in your language.

Follow the wring diagram on the top of the unit to connect the camera.

Use a translation site to read the first page, you obviously have not or you would not be asking if you can put a KGL MCU on a KLD unit !

An OEM booster is a booster fitted by the manufacturer of your car, look at the base of you antenna and see if it has a power wire.
[MTCB Android Head Units Q&A] giornistrani:

How to add a missing power button

---
[MTCB Android Head Units Q&A] pants001:
Hmm ok tried joining these today. Made radio worse so cant be right.

Better solution for radio was to install TuneIn Pro app and feed a 3G dongle into glovebox. I can now get my AM station static free and in stereo.

I can also record and listen to podcasts.

Very happy now
[MTCB Android Head Units Q&A] Buffen:

I have Huifei KGL car unit .How can i Get Into Bootloader. My unit don't have front usb
[MTCB Android Head Units Q&A] pants001:
Yeah interesting thing is the 3G dongle says connected by "Ethernet"

Some apps look for 3G/4G or Wifi and dont recognise Ethernet as being connected to the internet (poorly written in my opinion)

TuneIn and spotify etc are ok. TuneIn Pro has quite a nice interface for car.

For interest im using a vodafone USB 3G stick.....its a Huawei K4203

$14 for stick and 3GB of data from Coles supermarket / Australia

Poor sound quality with connected phone

I have KLD 2.40 MCU. When my phone is connected, the sound quality is poor. In Poweramp with V4A too! I tried to disable stream music from my phone and now the sound quality is as good as my phone is disconnected. I don't use audio stream from my phone so not a big deal but strange.
[MTCB Android Head Units Q&A] kaween:
Hmm. [MENTION=2091714]Buffen[/MENTION]&Co.

Tunein Radio as solution for (good) FM reception ? Really ? *shudder*.

I've been a Tunein user till mid 2014 or something. I've seen, or better said heard, how the sound quality of Tunein went down the drain over time. Maybe the situation is different in your country, but over here stations that used to "broadcast" in 128kbps AAC have gone down to 64kbps mp3 ... and sometimes even lower. Stations I used to listen to "gone" due to restrictions. Good sound quality ? Nope. Not by a long stretch.

And a redesign of the UI in 2014 that resulted in a unusable "car mode", and a "normal" UI that has been made so bad that I can't even display the Song&Artist info anymore without cutting of info although you have a screen of minimum 800x480 ...

I've started using Xiialive for those reasons. The Favorite-management is a pain, other than that it fits my needs better, even in the free version.
[MTCB Android Head Units Q&A] giornistrani:
I have the same language problem too ...

---------- Post added at 12:07 PM ---------- Previous post was at 12:01 PM ----------

Music with USB / SD works well in your car stereo? Not hear any interference?
[MTCB Android Head Units Q&A] Buffen:
I stand corrected :D

I do have, and use, XiiaLive Pro - ver. 3.3.0.4!

But I have also bought TuneIn a while ago!
[MTCB Android Head Units Q&A] pants001:
You might have miss-quoted me there. I didnt mention FM

I listen to an AM station (Mono) which is mainly talkback radio. The reception is very poor and cuts in and out (even with my original unit)

For this reason streaming it is infinitely better and now its in stereo for me.

Ill have to look into Xiialive if you say its better though. Thanks for the tip. :eek::good::p
[MTCB Android Head Units Q&A] typos1:
You need to remove the antenna to find out if there is a power wire at the base, but you probably need a power injector, there is loads of info online for this on VW cars. Search booster or power injector and your car "antenna booster VW Polo" etc.

There is only English and Chinese available [MENTION=6516720]giornistrani[/MENTION] has the same problem - read the last 20 pages there may be a solution if you can translate some files.

Was just saying, at least it should be easy top add more RAM then, providing we can find the right type.

I think it is just the Astra/Cruze models that dont have a power button ?
[MTCB Android Head Units Q&A] giornistrani:

Don't these hu's have a remote, by any chance would the remote on/off work? I think some remotes would hold the button on a long press. It a long shot if the circuit even works in some of the modes they are in. Just a thought.
[MTCB Android Head Units Q&A] pants001:
Ok installed it and yes. blows tunedIn out of the water for design and interface.

I still however prefer TunedIn for having stations and podcast in the one program.

If Xiialive could subscribe to podcasts i'd be over in a flash
[MTCB Android Head Units Q&A] Enc0der:
great to hear, thanks!

by the way, is hardware button remapping different from the basic "default music app"/"default video app" feature that already exists? Because the end result is the same, it "remaps" my "Media" hardware button (which is great!! thanks!!)... If it is done in the different (easier?) way then a complete buttons remapping, then is there a possibility to quickly&easily add "default TV app" as well? just wondering...

Question.

I have one of the units from Pumpkin, Model:	KD-C0223.

I want to connect my BT obd2 device, but I cannot get the blue tooth to connect to anything. it will say that it is paired, but not connected.

What do I need to do to get the device connected.

Heck at this point, I would be3 happy just to see it ask me for the pin number to connect, but it doesn't even do that.

Oh, and about powered usb hubs, I bought a 12 volt 7 port USB hub off of Amazon for my old Ouko Android 6.2 that works perfectly with the Pumpkin head unit also.

This is the one I bought.

www .amazon.com/EZOPower-7-Port-Premium-Adapter-Chipset/dp/B00IM77NRG/ref=sr_1_5?ie=UTF8&qid=1430589312&sr=8-5&keywords=12+volt+usb+hub

Remove space after www

Just cut the connector and wire off of the power supply that comes with the hub, and wire it into a fused connection in your car. Center pin is positive if I remember correctly.

I'm running a 240 gb Intel SSD series 3 drive on mine, and even running at USB 2 speeds, it is super fast on this head unit.
[MTCB Android Head Units Q&A] agentdr8:
This was a known issue that affected 4.4.2 roms. Also, the BT stack on these roms don't have the pin pairing prompts enabled, so you'll never get the popup. It uses the fixed pin value to do pairing, so make sure it matches whatever the device is expecting.
[MTCB Android Head Units Q&A] ESTIMULO:
Any advance in remapping hardware buttons?

Thanks
[MTCB Android Head Units Q&A] ScrewGoogle:
Thanks for the very fast response.

Would a third party blue tooth app help with the issue?

There was one I needed to use on my old ouko unit because the built in BT adapter had limited capabilities, so a separate BT dongle was needed in that case along with the app for BT.

I'll have to give that a try and see if it works.
[MTCB Android Head Units Q&A] Amelios:
I used to be able to pair, connect, and use my BT OBD2 device by using XposedMTC, but for some reason I can't anymore. My phone can pair and connect just fine. Did I read somewhere a ways back that you had changed something related to the BT, and maybe you needed to undo it?
[MTCB Android Head Units Q&A] passador83:
This is terrible. I'm not flash any firmware but recovery. Unless is the same. After lashing first time boot normally but after I did factory reset appear problem. Thanks for your time. It was very helpful.
[MTCB Android Head Units Q&A] agentdr8:
Yeah, I added a device name filter, which for some reason isn't working right. So until I can revert this change, you'll probably want to start with the older version of XMTC, pair your obd adapter, and then upgrade (if you want).
