For the car logo: there should be a menu in the settings called extra settings.

i have a toyota sienna, not sequoia but it likely has the same connector. i bought a Metra 70-8114 Steering Wheel Control Wire Harness for Select Toyota/Lexus/Scion off of ebay for $8 and just cut the wires to use the connector, found the pinout somewhere on the internet - works great. you can check on crutchfield if its compatible.
[Android Head-Units] fyid:
did you replace the initial image that comes up for a few seconds on boot, or the animated "android" logo that shows for 20 seconds after that? if the latter, can you explain how to do it? for the former there was a setting in extra settings that let me change mine to a toyota logo.
[Android Head-Units] BiliTheAxe:
I had to add a Dodge logo to the automotive logos under settings, because the unit does not include one. (Most Dodges do not allow for double din head unit installs, Except for the newer ones.) Mine would not either, so I had to custom make a bezel to allow me to install the head unit in my car. 2004 Dodge Intrepid SXT.

In the above image you see the circled app icon. That is what allows you to change the Android boot logo. You cannot add your own custom one, but you can choose from premade ones, or as I have done, none at all, so that only the vehicle logo is displayed.
[Android Head-Units] fyid:
thanks, i had noticed that a while ago but was too chicken to try it since i had read that others had problems when they changed it. then i forgot about it. i have just tried it out and see now that mine has an itopway animation, which i'll use for a bit ;).
[Android Head-Units] nosidefcp:
i guys. i bought the unit from the below link

http://pt.aliexpress.com/item/Quad-...-Car-GPS-Navigation-BT-Radio/32617239524.html

im pretty sure its based in this one from the topic. can anyoneconfirm?

all working fine, except the gps. it takes ages to lock on the sattelites. any fix?thanks
[Android Head-Units] fyid:
I don't know if you have the same type of unit, maybe post the version numbers from your settings about menu. But, I've noticed the GPS antenna position is critical - I had to move mine a bit forward, further under the windshield to get a solid lock.
[Android Head-Units] nosidefcp:
thanks. ive just opened a thread. i have the unit in bootloop. i changed the bootlogo and now its just in bootloop. ive managed to install one of the firmwares here, but the bootloop remains. is there anyway i can solve this? maybe by mouting the unit in the pc so i can remove the bootlogo that is giving problems...?
[Android Head-Units] nosidefcp:
jesuuuuuuuuuuuuuuuuuuus. anyone can help me out? i now exactly the file in the folder /etc/logo/ that is causing this error. i managed to find the original fw and flash it. it takes about 5 minutes to flash, but at the end, the problematic bootlogo remains.

since my unit its just touchscreen without hardaware buttons i think i mayube need a full firmware flash that will will flash the logos and erase all settings, or someway i can mount the unit in pc so i can delete the logo
[Android Head-Units] fyid:
sorry, i've no experience with anything but an upgrade/reflash, which you've done. maybe ask your reseller how to use adb (pc connection) with it?
[Android Head-Units] nosidefcp:
Video of the issue.

https://youtu.be/MVTp9QdTRnI

I managed to flash 3 firmwares. Its by sdcard. They all flash fine but somehow this wont format or wipe the bootlogo preferences so the issue maintains
[Android Head-Units] nosidefcp:
basicly whath i need if a firmware or just a file that will send a command to delete a file in /etc/logo . the corrupted file is audi.png

i cant connect to the my pc from any of the two usb ports from the unit. the one hundred fw i flashed wont format the logos...i dont know what to do more...
[Android Head-Units] fyid:
i searched the "android head unit" forums for some answers and found this one which might be interesting, although i have no idea where you would find the "full format" firmware specific to your unit: http://xdaforums.com/showpost.php?p=63306311&postcount=7614

also found this one fwiw, but i think you have no hardware buttons: http://xdaforums.com/showpost.php?p=59413909&postcount=6567
[Android Head-Units] nosidefcp:
Thanks m8. Ive used all the full formats i can find, and none of the firmwares are acepted by the unit. Update starts, update end. The only thing i can flash succesfully is the fw for infidini and from kaer, but those fw wont format alwhat i need them to format.
[Android Head-Units] BiliTheAxe:
Does your unit have a small hole in the front that contains a reset button, and if so, have you tried it yet?
[Android Head-Units] nosidefcp:
yes it has. the only thing it does is reboot the system, or, in case i let it pressed for a few seconds, it forces the unit to go to the force flash. the issue its that every firmware i try, even the two from kayer that flash sucessfuly, wont erase the bootlogos or replace them, so after the flash, im back with the bootloop
[Android Head-Units] BiliTheAxe:
Try disconnecting the unit from all power. Disconnect the battery for a few minutes. 10 to 15 minutes.

I have seen posts in the past where this has corrected the issue.
[Android Head-Units] nosidefcp:
The batttery of the car or just remove the radio from any power source?gonna do that and let you know in half an hour

Other thing, my unitw force flashes from usb, not from card. Is there anyway i can connect the unit to the laptop or mobile phone by usb?
[Android Head-Units] fyid:
you probably needed to enable usb debugging in developer settings while the unit was working...
[Android Head-Units] nosidefcp:
cutting all the power for about an hour doesnt work also.

ive noticed that if i connect a usb cable from the unit to my laptop and press reset, instead of showing the bootlogo and rebooting all te time, the unit will just light the screen and stay dark

by the way, the unit is this one. im in the right place yes?

[Android Head-Units] fyid:
if the version #'s in the marketing description are the same as what's in your unit it does look very similar to my version #'s (see link in my signature), so you're probably in the right post. but, you still may need to bug your reseller to try to get the full format firmware for it, if noone else here has it.

im gonna need to create an account in 4pda to see if someone there have any solution. anyone can create me an account there?im trying but the i cant enter the captacha at registration

---------- Post added at 04:00 PM ---------- Previous post was at 03:54 PM ----------

to make the unit enter the force flash, i have to press reset and turn the key/ignition on at the same time, then release reset and ignition off/on in a second. this will force the device to the "UPDATE START UPDATE END". if i could enter recovery it would be a nice thing. i dont even think this device has a recovery

also here, post 23, there is the MCU and system files, but i also cant download it. anyone can do that?i think the ALL WINER MCU .ZIP that contains system might be what i need. thanks in advance
[Android Head-Units] nosidefcp:
two pictures to show you the update process.

i can succesfully flash the unit, but it wont flash the MCU. i have 5 files in usb, 4 from the kayer firmware, and a MCU. maybe because te mcu isn compatible/acepted by the unit. the thing is that the unit its to recent and i cant find the MCU that comes with it anywhere

The MCU i need is 5.3.18-36-13-E50201-160106

Dash cam?

I just installed my head unit from ali express seller road leads and this seems to be the right thread for it. All the passwords have worked. I have system version 4.5.8_2016010829 and MCU version 5.3.18-61-10-C00101-160303

Everything works so far (with a little work: Google play services error, had to use root king version 4.5 as latest didn't work) except my dash cam. I bought a Chinese "dvr" cam from aliexpress that was advertised as compatible with android 4.4 and being for "dvd android car navigation systems" It has

I tried it with the dailyroads voyager app with custom resolution 640x480 h.264 30fps and tried both high and medium bitrates. I only got a black screen where the video should appear.

Bluetooth Problems with Android head unit

I have this headunit in my car. I have an iPHONE 6. When i connect to bluetooth and stream music, the highs are scratchy and its not enjoyable at all. How do i fix this? It says i have to have BC6 selected. When i do that it wont show bluetooth so i select BC8 and it will connect then. Any thoughts?

I have the same problem. Audio in general out of this unit is garbage. Previous hui fei unit sounded much better for music. If anyone has found a solution I'd love to hear it.
[Android Head-Units] thatguychad:
This unit feels like a downgrade in every respect from a Hue Fei unit. Why did you change?
[Android Head-Units] nosidefcp:
im very satisfied with the sound quality of the unit. i tested the unit in a smart f2 and the sound was good. now its installed in my Alfa Romeo 159, with a full boose system, along with a aftermarket subwoofer and the sound quality is great. this applys to music reproduced from the unit memory, usb and memory card. offcorse i wont expect the same quality for sound transmited via bluetooth. eevry units i had in the past, the quality in sound via bluetooth wasnt very good, and i think that is a fact and is easy to understand why. messing a litle with the equalizer will help, but not much.

Tried it, but I do not understand how to use it. Should I press start first, or in which order should I configure the buttons? Thanks
[Android Head-Units] fyid:
yes, as i recall the front panel settings work similar to the steering wheel control settings... you press START and then press one of the choices, then press the corresponding front panel button. repeat the choices/front panel button until you're done and then press END.

i may be forgetting a bit, haven't changed them recently.
[Android Head-Units] delarium:
Excellent, got it work! Thanks alot! Tried the steering wheel button changer, didn't work though. Should it be the same procedure?
[Android Head-Units] fyid:
same procedure but the settings app is different, look for the steering wheel control setting - i'll look at mine later to remember where it is.

[Updated:]

Steering wheel settings are right under general settings, works the same. Have you hooked up the SW1,2 wires in the back of the head unit? What car do you have, I read these head units only support Japanese model SW controls as is.
[Android Head-Units] Hisma:
anyone heard of redpower firmware? It looks really interesting. It is supposed to be compatible with our specific model.

https://www.youtube.com/watch?v=BwQiDSEIKfg

That unit is built specifically for my vehicle, but you should easily be able to change the extra settings to match your vehicle.

Anyone care to try it? Here is the link to the firmware -

Steering Wheel Control

Hi all, I have been lurking for a while, then about a week ago I got this model off Amazon. I have a 2008 Chevy Silverado with the existing non-bose system. I had speaker issues with the factory unit. Updated the speakers to 4 Kicker 100watters. So on Saturday my buddy helped me install the Android unit into the Silverado. We installed a PAC Audio RP5-GM31 adapter between the factory connectors and the Android unit (Tonghai 2nd G). I was pleasantly surprised when it all started working and quite well. Its running the standard config:

R16 1.6G Quad Core

Android 4.4.2

MCU 5.3.17-11-10-xxxx-yyy

System 4.5.6_20151230 and DVD 2.13.15-xxx.

My question is there were two wires a K1 and K2 that were designated for the SWC connection on the RP5. I connected the K1 to the blue on RP5 and left K2 hanging.

When I configured the HU on the SWC options. I didn't quite get all the buttons working. It basically identifies them as "L" or "R" and works somewhat.

What was the correct wiring of K1 and K2 ? or is there a correct way.

TIA for all help.
[Android Head-Units] Hisma:
depends on your wiring. Do you have the wiring diagrams for your SWC? If so, post them here and I/we can show you. On my car, I have some buttons on one circuit, and other buttons on another circuit. Both circuits are tied to the same ground. Without the wiring diagrams your question cannot be answered.

A new unit and firmware with problems

I recently got a new no-brand head unit which I think is based on the same one. It's specific for a VW Golf 7 and those are the details:

10.1", 1024x600 (I have a firmware update file that says KED1)

Processor: QuadCore-R16 1.6G

Android version: 4.4.2

MCU version: 5.3.18-11-11-453101-151209

System version: 4.5.8_2016010829

Supposedly it has the latest software installed. But I have 2 issues and I wonder if anyone can help:

1) Can't root, I tried Kingroot the latest version as well as v4.5.0 (120) but they both fail. Is there any other way I can root it? Even temporarily to troubleshoot a few things, backup some files, etc?

2) It has a BC8 bluetooth chip. Bluetooth used to work fine before but then it just stopped after I did a factory reset. The strange thing is I named the bluetooth device "somename" and then it was discoverable as "somename" but it refused to connect. Now I did a factory reset and the device name returned to a factory "iTopWay" name but the strange thing when I try to discover it using any mobile phone is still broadcasts as "somename". No matter what name I call it it is still broadcasting as "somename". And I can't connect to it. Also when it tries to search for bluetooth devices from the bluetooth app it finds nothing. Is there a way to find where the "somename" is registered and then clear it out? It seems like it's unable to update that setting and also when I change that name and reset the unit it will again revert back to "iTopWay" in the bluetooth app and remain broadcasting as "somename" so something tells me it's unable to overwrite that setting?? It's a strange problem that the seller is also unable to resolve. A system update doesn't really erase anything.

Any help would be really appreciated.
[Android Head-Units] delarium:
Installed this one in my head unit, everything went smooth and got installed correctly. However, now the headunit is silent. Cannot get it go give me any sound at all, neither from radio or spotify :(

Anyone with information on how to solve this is highly appriciated.
[Android Head-Units] fyid:
for kingroot, you need to be connected to the internet when it is trying to root. and you may have to give it time... mine seemed to take a while and i wasn't sure when it was going to finish... but eventually it worked.

for bluetooth, mine stopped working after a system update also. i read around and found that sometimes you can get it back by unchecking the BC8 box (found in extra settings i think), rebooting, and then checking it and rebooting again. at least that worked for me, no problems connecting a (cheap ebay) obd2 bluetooth adapter on it since.
[Android Head-Units] BiliTheAxe:
Contact the seller you bought it off of and see if you can get them to send you the correct firmware for your unit. The MCU firmware on these things is not interchangeable between different models/vendors.

Just because the units might look the same, does not mean that the firmware is the same.

Everyone here tries the files found here at their own risk.

I bricked my dual core head unit that way, so I'm no longer willing to experiment with firmware.
[Android Head-Units] delarium:
Thanks for your reply, but actually I figured it out.

There is a setting under "Extra Settings" or something similar, where you can change what kind of unit it is. Cant remember exactly. There is 3 models of VW (in my case). As the unit was rendered useless (a HU without audio autoput is in my opionon useless) I went for it. Unit did a complete restore to a previous MCU, and there it was.... sound. Missing "Car setting" app now, but hey, better that than no audio at all.

Hopefully somebody else will have benefit from this info above.
[Android Head-Units] sambacha:
Kingroot was connected to the Internet. It actually kept saying can't find a way to root it or something like that and I needed to wait until they figure it out. BUT today I tried again using 4.5.0 and it worked! So that is solved.

I tried the Bluetooth suggestion and it didn't work for me.

Is there a way to flash these units back to REAL factory state?

Also, is there a way to remove system apps like Car Settings? I compiled a new one with some changes and want to test it but since I'm using a different signature I can't update the existing one. Any ideas?
[Android Head-Units] fyid:
maybe try checking BC6 instead if you have a box for that? i went through all combinations rebooting everytime before I got mine back.

i've read on these forums about something a "full format firmware", but you will likely have trouble finding one specific to your unit - maybe ask your seller for it. see: http://xdaforums.com/showpost.php?p=63306311&postcount=7614

maybe titanium backup? i don't have it but have used other apps without much success - i was able to freeze the radio and add a differently named radio, but couldn't map steering wheel or front panel buttons to it, or have it start on poweron like the original radio (i.e., only when it was on before you shutdown)... i just gave up and mostly use the original apps now.

---------- Post added at 05:48 PM ---------- Previous post was at 05:46 PM ----------

also, seeing as your unit isn't bricked, what about the factory reset inside the settings?
[Android Head-Units] sambacha:
I checked all combinations with BC6 and 8 with reboots and it never worked. My problem is in BC8 I can see the unit but I can't connect to it and it can't discover anything. Is there a way to install my own BC8 driver and phone app from another unit?

For the Car Settings app I was able to remove the existing one (from priv-app) using an updated Es file browser and installed my version when I named the apk file the same as the original.

Factory reset doesn't fix Bluetooth at all. I'm in continuous contact with the seller and they're trying but don't seem to know what's wrong. I don't like the recovery these units have and I really hate the way they have setup Bluetooth as it looks like a hybrid of multiple apps and not solidly built.

They don't seem to have a factory image that wipes it even though I requested it multiple times and they are really trying hard to get it working.

Here's another unit

Got this unit from here http://www.aliexpress.com/item/10-1...-For-Toyota-Prado-2014-Audio/32252188377.html

Interesting that it reports Android 5.0.1 but it's really 4.4.2. I got the big kit-kat logo by tapping on the android version number a bunch of times. I like this unit, its a bit slower than my old HuiFei. But it runs absolutely every app. Even more than the HuiFei. Would be nice if Kingroot worked, it just won't.

So you don't buy these for the Bluetooth, but everything else is good.
