[MTCB Android Head Units Q&A] koimr:
Hey Ken,

Just saw this post now - I actually have something similar going on in my vehicle too.

Normally I can lock/unlock my car from inside my house but when the head unit is doing its sleep thing (currently at 30 mins) then the range is severely reduced - I have to be right beside my car for the fob to work.

I also had a problem before with my interior LED lights (not the cabin ones, the heater/AC/gear/steering wheel illumination ones) not working when I installed my head unit and I found it was a loose wire in my wiring harness so I suspect this is something similar as well. Because it does work, just at a severely reduced range, I haven't really bothered to pursue it.

In your case though it's actually making your key fob useless during the sleep time so my suggestion would be to go over your wiring again to see if anything is loose.

For me, I used a Metra harness specific to my vehicle (KIA Optima) and the loose wire was one of the speaker wires inside the harness - it was loose enough to affect the lighting but NOT affect the actual speaker which threw me off for a long time.

Good luck! :)

To enabled the feature to turn the screen off if you don't have it, find this entry in the build.prop.

ro.product.barbacklight=false

Needs to be:

ro.product.barbacklight=true

EDIT: Wrong thread, meant to post that in the HotAudio specific thread. Not sure if the same with other units.
[MTCB Android Head Units Q&A] RubbedLung:
Yeah I just verified that but just to be safe I uninstalled and reinstalled without my SD cards in and its still doing that same thing. I select the app that I would like to over-ride my audio, then when I select the "my audio" it simply takes me back to the xposedmtc interface where you select which app you'd like to override with. Its really weird. Anyone ever had this happen?

Need your help

Hello guys ! Sry for my bad english ... ( I´m from germany).

Let´s come to the story....

My friend got the Erisin E2053b. In the beginning it went very well, but suddenly it got stuck always on startup logo.

(Car : BMW E39)

So we tried to make a update from MCU and update.img .... then it startups again, but buttons did not work and the keys did not illuminated anymore.

The real problem: We can´t make a update from MCU or update.img anymore ! it always stocks at installing mcu or it stock checking firmware ... Can someone help us to get this Erisin to full working again?

BIG THANKS FOR YOUR HELP :)

Hi

I'm going to buy Huifei for my car from AliBaba , is this there official page ?

and which you guys prefer KDL or KGL unit ?
[MTCB Android Head Units Q&A] leparainn:
We´re trying to update via recovery.

Maybe the recovery is damaged or something?!

On the botton of the Recovery we get 3 Errors:

"Recovery system v.4.4.30

E:failed to mount /ant/external:sd(No such device)

E:failed to mount /ant/external:sd(No such device)

E:failed to mount /ant/external:sd(No such device)

we are take some MCU KGL5 to the SD card and Gps Slot but it just goes to:

"installation mcuing start.

Then nothing happens and after some minutes unit restarts and get the error "kein Befehl" (no command)

If we try to take some update.img it´s almost the same and just goest to:

"Find and check firmware..."

EDIT:

The Problem is, that we dont know ... is it KGL or KDL?! (E2053b)

And we dont have any known how to set the Factory settings.

I still have the problem, that my sound output is not activated after boot. The Music app is not able to start the sound.

My fix: open raido app, close radio app, start music app. Then it works

I have a KLD1, MCU 2.55 with sound fix, lastest official Firmware.

Any ideas?

Since I'm not to sure how you would have done something like that would you please check? This would be the best solution to have the setting in the program itself choose the right folder.
[MTCB Android Head Units Q&A] vdubskey:
Already tried that, it still doesn't work. The only way to change settings is to start navigation and then goto settings and make your changes. Only when navigation has started will the settings be shown in landscape. Then exit and restart and you should be good. I never change my settings after I get them dialed in so it works for me.

Hello

That with the tomtom is very bad. I have now try all now. But didn't get it to work.

I need the Europe map from tomtom and try to download it in my Android tablet on external SD card and the go to the unit and install pcv builder and then install tomtom. And the make the right lsd line to the path. But tomtom don't find the map .

What I have found out you need to download Europe on the unit and then you need to copy it to sdcard and then should pcv work.

My problem is that Europe is 6 gb and my car is run out for power before it is finish. So I need to take the unit out of the car and use it on my PC. But then comes next problem when I update the radio firmware can I do all over again with the unit out of my car and into my PC and so on

Hi,

Yes that was the first thing I checked, but I had the same problem when it was installed in my Ford and now I have a Toyota RAV4

with a new harness and have the same problem. As a side line I also have the severely reduced range on the Fob I have to be about

2 feet from the doors before they will open. So the only common item is the HU as both cars had a different harness to connect it.

So I guess I'm just going to put up with it.

Help me!

Hey guys!

First of all I have to say that this seems to be a great community and reading here makes me keep up hope.

Well I bought 3 different devices. And you may have experienced that there is often no manual and bad support. So I had a few problems with the NAND Flash and with the structure of saving data on Android.

Well I'll be honest - I'm from the fruity side of the medallion when it comes to mobile devices. Starting using android in my car was a decision which took me a while.

-So far so good-

Well to keep it simple: you may can tell me about the Memorystructure of all of theese devices? :confused:

So here are my questions:

1) Why is my data and all my apps saved on "SD CARD" (Nand) erased after every boot?

2) Is there any (not fancy) way to tell Android that I would like to install apps on p.e. my normal micro SD memory?

3) Do you experienced the same: Spotify only has output at the front speakers? How could I fix that?

My Device

DEVICE 2698GD from ERISIN (RK3188)

Well they send me an update (KGL_rk3188_h(20150708)) did not expect that my problems are solved.. so I would appreciate it if you help me with this. Many many Thanks and keep up this awesome Work!

Hello.

Yeah, I did something stupid and hope that one of you can help me out.

Bought a new quadcore Android 4.4.2 head unit off of ebay. with the RK3188 chip in it.

I was going through the settings and stupidly changed the resolution from the stock 800x480 to 1080X and now I can only see half of the screen and cannot access the settings menu to change it back.

I tried holding the power button and reset button to reset it, but it will not reset.

Any suggestions for how I can change it back, or at least reset it?

Thanks in advance

First of all I want to thank Malaysk for all his great work that gave to us spending a lot of his free hours. Lately I have a strange problem. When my lights are on, sometimes my screen is off but if I press it I can change stations or change a song. Seems like only the brightness is off. If I switch my car lights off, screen is on again but switching again the lights on, screen goes off. It doesn't do that very often but it is a little bit strange. Any ideas or some settings that I didn't see? My unit is a KLD RK3066 800x480. Also changed the mcu to an older version (2.55) but it didn't help.

Pumpkin Head Unit

I just purchased a head unit from Pumpkin (model C0241).

This forum has been very helpful in eliminating several of the bugs but I am still having a few problems. To address them, I thought I'd start with one of the custom firmwares. I was unable to determine which of the mcu.img files to use since the description of my mcu did not match any of those in the repository. My "about device" screen includes this in the "build number" field: MCU: 5701-20150901-141949-V01.

So I decided just to concentrate on the ROM upgrade and downloaded Malaysk's latest firmware for a 1024x600, RK3188 unit (9/9/2015). The unit recognized the update.img on the thumb drive and rebooted but I got an error message upon reboot and it would not load the firmware. Is this the incorrect firmware for my head unit? If so, could someone point me in the right direction for the proper firmware and mcu?

Thanks,

Tom

All android apps that output sound go through the MCU EQ. So in Poweramp, you're actually double-equalizing, which could potentially sound bad. Either set PA's EQ to off, or adjust the system-wide EQ to be more flat.

He does not have a HuiFei unit, or even one of the HuiFei-type ones. The Pumpkin model is AL-C0241-US-A, not "C0241". The first part of Pumpkin model numbers indicates the manufacturer - KD is Klyde is KLD, etc. I have no idea what manufacturer AL refers to, but it's not any of the known manufacturers of HuiFei-type units. The MCU version is also a completely different format that that of any of the units covered by this thread. There's no reason to believe that Malaysk's firmware would work on it.
