[MENTION=7017702]imableeblob[/MENTION], when you get a chance, you can remove my reported issue about the SWC not sticking. As I said I fixed that. The SWC app was confusing to me as I came from a hui fei unit previously and mapping controls was different. Figured it out now.

There is another annoying problem I am having that I am wondering if others are having though. I have the unit set to have 1 hour shutdown delay. If I have any music playing, the music will continue to play when the car is shutdown (I don't hear it but I know it's playing b/c of the position on the track). When I start back up the music picks up from however many minutes I had the car off. This leads me to think the unit is not properly being suspended when shutdown, which is a bit concerning. I want to know if others are having this issue too. I hope it can be fixed. As of now the only way around it is to pause my audio before I shut down the car, which is annoying.

USB keyboard/mouse doesn't seem to work. [MENTION=3081576]sciallo[/MENTION]

I have used a USB keyboard with my unit, but have not found any blue tooth keyboards that will work.

Sub out only works with radio, nor power amp Pandora Bluetooth or even built in music app. I ended up connecting my sub woofer amp to the rear channel. [MENTION=3081576]sciallo[/MENTION]

My sub out works with all audio sources so far.

What's your system and mcu versions?
[Android Head-Units] Hisma:
here is a system update provided by my seller, dated 2015-11-23, so a little over 1 week old.

https://www.dropbox.com/s/yhe65pb5f...024-600-V4.5.4_20151123_KED1(linshi).rar?dl=0

Update instructions as follows -

1. extract file to root directory of the SD card and also copy to the root of the GPS card (not sure why you need in both places but this is instructions)

2. with the unit powered off, re-insert the SD cards. when you power on the unit go to settings -> general -> system update.

3. If necessary you may need to choose your car model in settings -> general -> extra settings (code 123456) -> model choose -> choose your car model

not sure if this is both an MCU & firmware update, or just a firmware update. I will apply this update later today and let you all know how it goes. I'm hoping it will fix some of the annoying issues I am having.
[Android Head-Units] BiliTheAxe:
My unit is the one on the first page of the thread, on the top left.

---------- Post added at 12:12 PM ---------- Previous post was at 12:09 PM ----------

Then I do not think that update will work for me, based on those instructions.

My unit does not have a slot for a GPS card. There is just a hole where one could have been mounted, but wasn't..
[Android Head-Units] Hisma:
They loaded software onto your unit somehow, probably via USB. You'll have to find instructions for that. But if hw is the same the files should work for you.

---------- Post added at 02:33 PM ---------- Previous post was at 01:39 PM ----------

Executed the update. It was just a firmware update, not MCU update.

I followed the instructions I stated and it worked fine. You need to be patient, it takes about 5-6 minutes to complete so even if it looks like nothing is happening just keep waiting.

Here is new software version -

I noticed no difference, all my outstanding issues seem to still be present, though I do notice that if I try to connect to my phone via BT from the unit, it does pair successfully. It is still not auto-pairing, but on my previous software it wouldn't even pair at all if I tried to connect from the unit. I got around these issues using tasker so no big deal.

Music still plays during delayed shutdown, this is really annoying. I have to pause music before I shut down if I want to restart from where I left off. I still seem to freeze occasionally on bootup. This is also really annoying, but it only takes a few seconds to catch that it froze, and I turn off/turn on my car and it usually works again.

New unit?

Is this unit also one of the new Tonghai 2nd gens?

http://www.aliexpress.com/item/Andr...Quad-core-with-2-DIN-Car-GPS/32500178991.html

Seems to have a 1024x600 screen, the R16 quad and GPS+Glonass support.

Yup.

I found this alternative radio app (reference, source code). Works well but I am unable to set preferences (force closes -- I would ask the developer, except that I do not speak Russian...). I am on 6.0.1, it may work better for you on 4.4. I have also downloaded the sources and I am poking around in the hope of finding a solution for the force close, but please do not hold you breath as I am not an Android developer.

I believe (but I may be wrong) that the equalizer only works with the MCU apps, but no matter what it should not loose settings. Could it be that bad wiring cuts power completely to the unit when you turn off the ignition? The usual symptom of this is that the radio does not start on the last station (even if the presets are maintained), but it might also cause loss of equalizer settings. This being said, this is more of a shot in the dark than anything else.

The same goes for Poweramp (it should not loose settings that is, but this should not depend on the power status).

Probably. For me the winner was Kingoroot (note the extra "o") but again I am on 6.0.1. People on 4.4 have reported success with Kingroot.

Moving apps to the external SD(s) should work, not sure about an external USB drive. I have not tried any of this though. As far as I am concerned root is a must because of the Xposed framework which is my killer app (err, framework).
[Android Head-Units] virnoche:
Thanks for taking the time to answer. My unit is powered correctly in fact there are many things that mine does such as stay on for the predetermined time setting after ignition etc.....mine literally lugged into the factory wiring and everything worked as designed. I put a wireless backup camera in, an OBD2 reader and Torque installed on the HU.....everything works like a charm so far. This is one more reason I hesitate to root. I see many posts on here on Bluetooth not working.....etc, makes one wonder if the rooting has some effect. I have rooted several old Android phones for fun to see what was possible....

The equalizer working only with the MCU apps makes perfect sense. It DOES however adjust settings for other apps such as Pandora....but you have to open the equalizer separate obviously. I actually LOVE this equalizer and I don't think many people really understand what we have here! With a wink....all I will say is this....two smiley faces with the two sets of adjustments is NOT the answer! Its parametric......the only shortcoming of this equalizer is there isn't any documentation of the range of the center frequencies or the 'Q' in which they are designed around. With an understanding of just what a parametric EQ can do this one actually can make your speakers sound very good! and If you add an outboard amp and a single subwoofer it gets even better.

Overall I really love this thing.....the only thing I wish I could do is move apps to external USB. Android previous to 4.0.0 could do this......and now Android 6 will do it again.

Thanks again for your help.
[Android Head-Units] sbruda:
Oh well, it was a shot in the dark...

Rooting should not have any effect on these whatsoever, it is what you do with a rooted device that may cause problems. If you only plan to move apps then I do not see what can go wrong. Worse comes to worst you can always restore to factory.

That's good to know and I will certainly test it myself when I get a chance (given the January temperatures in my neck of the woods my unit is still on the bench with no speakers...). I do not find obvious that you have to adjust the parameters on a per-app basis; I would have expected that the equalizer adjusts the parameters of the hardware preamp directly and if whatever adjustments are done once apply to everything. Weird...

You are quite welcome, except that I was not much of a help...

Hi Guys,

Great thread. Tons of useful info.

I have the Seicane 9": http://www.seicane.com/8-8-inch-tou...sd-3g-wifi-steering-wheel-control-video-1080p

I read the entire thread, and I didn't see an answer to this question, but I apologize if I missed it. Has anyone had any luck linking apps to the external SD card?(this unit has an SD card slot inside the housing, as strange as that is) I'm trying to get some apps linked to the SD card to overcome the limited internal memory(small number of apps that can be installed in its factory state).

I have the SD card set up with a 1.5G Ext4 partition, and the rest is Fat32. When I 'Recreate the mount script', I get an error that states:

"k_shell/10063:11482:[38]:can't create/system/bin/debuggered: Permission denied" As far as I understand, this means that the system does not have the correct read/write permissions for the SD card.

Even though I get this error, it still allows me to link apps to the SD card. The problem is that when I reboot the head unit, I get a message that says, "Continue? 2nd partition was not mounted some apps might not be detected. A soft reboot is required to mount." The linked apps are gone until I do the soft reboot. I assume I'm getting this message because the head unit is fully booting before the SD card has been mounted.

The weird thing is that Apps2SD was working perfectly when I first set it up when the head unit was new. I could get a bunch of apps to be linked to the SD card, and I would never get that 'soft boot. error(the linked apps were there on first reboot). I started getting this error when I did a factory reset and started over. (in an attempt to fix the Google Play Services error - before I read on here that the HU comes with the wrong version...)

So, maybe the read/write permissions of system access to the SD card got changed somehow? I can't seem to get it back the way it was no matter what I do (full factory reset, SD Card Fix app, etc).

Does anyone have any thoughts on this? Has anyone been able to link apps to the SD card on these head units? Any thoughts on how to fix the SD card R/W permissions or to fix the problem in some other way? Or, does anyone have any other way to get more apps on the device (increase internal memory)? I've tried AppMgr III, and only very few apps are 'moveable'. I've also tried to force move them with Titanium Root, but the apps disappear upon reboot (I assume because the SD card gets booted too late and/or the SD card R/W permissions(?)).

Any thoughts?

Thanks!

Patrick
[Android Head-Units] pfarley11:
Just to add a detail: I just got an email from Vicky Bonick, the developer of Apps2SD. She says that some custom ROMs like the one in our head unit have the system partition locked by the kernel. Does anyone have any thoughts on how to correct this if that's the case?

Thanks!
[Android Head-Units] dud89:
Here's a permanent solution which is to flash the following firmware to re-partition the MBR to 6GB/7.2GB instead of the almost useless 1.4GB/12GB partitions. Here is a link to the procedure in Russian, google translate does a good job explaining what is needed and how to flash. You will need a USB A to A cable that is wired 1 to 1 on both side.

Even so it took me over 2 hours to finish from flashing and fixing everything since it seem to have formatted the system and all the panel keys.

[Android Head-Units] pfarley11:
Thanks! Actually, I just discovered that forum. I joined RedMod, and I've been talking to Ilin (mobi97), the developer, about doing that flash, but I've had a lot of trouble getting my PC to recognize either USB of the HU.

I have this unit, by the way: http://www.seicane.com/8-8-inch-tou...sd-3g-wifi-steering-wheel-control-video-1080p

I have tried by putting the unit into recovery/flash mode via grounding one of the SWC keys (key1/key2), and I've also tried it using the APK that RedMod developed (com.tw.updatepc), and I just can't get my PC to see the device.(to install the driver)

Has anyone else had this problem? Happen to have any solutions?

Thanks a bunch for your help!

Patrick
[Android Head-Units] dud89:
First thing to check is if that you have set "USB debugging" turned on under "Developer options". I used a old computer PSU and grounded "Key 1" to one of the molex connectors. Start the device with the USB already plugged in. Try plugging and unplugging to the computer or use a different USB port on the device. Took a couple of time to get to that menu for me.

bootloader problem

hi, sorry for my bad english but, after a bootloader modification the screen is black permanently on boot. is possible to return to the factory settings?

in a Ru forum i found this

"Ceaning section the DATA Attached file3072f462-8747-11e5-bf6c-000c29ba27c0.rar (639 bytes) "

this clean all my data?

..of course, the download was no longer present..

Thank you
[Android Head-Units] pfarley11:
Okay. Thanks. I will try it again.

By the way, did you have more luck grounding Key 1 or using the RedMod USB flashing APK? Also, did your computer recognize and pull its own USB driver, or did you load a driver in advance?

Thanks!
[Android Head-Units] dud89:
Had more luck grounding key 1 as the Apk didn't seem to do anything other than freeze the unit. The first time the computer detected but could not find drivers and have to load the driver through device manager.
[Android Head-Units] pfarley11:
Do you remember which driver you used? Or, is there a driver I can download?

Thanks!
[Android Head-Units] pfarley11:
I am finally able to get the device into flash mode, I think. (black screen and my PC recognizes that some new device connected). However, my PC is not installing any driver automatically. When I go into the device manager, I can try to manually download a USB driver, but none of the ones I've tried so far have worked. The PC is not able to find one online, and the only relevant drivers it could find on my computer were the following: 'Android ADB Interface', 'Android Bootloader Interface', 'Android Composite ADB Interface', and a 'Samsung ADB Interface'. I tried each of those, and the Phoenix flashing tool seems to be unable to recognize my head unit with any of them.

Do you have any suggestions on what driver to use and where to find it or how to force the PC to pull the correct driver?

Thanks a bunch!

Patrick
[Android Head-Units] dud89:
The drivers are at the last post of this link UsbDriver.zip: http://red-mod.ru/forum/viewtopic.php?f=36&t=99

You should be able to just update the drivers through device manager. There are some instructions there for troubleshooting but should not be necessary.
[Android Head-Units] pfarley11:
Thanks! I don't know how many times I looked at all those RedMod pages, and somehow I missed that a link to the USB driver was included . . . I'll try this tonight.

Thanks again!!
[Android Head-Units] pfarley11:
I was finally able to update the USB driver on my PC and flash the unit with IQ Navi v1.25. Unfortunately, it appears that 1.25 does not have a resolution choice compatible with my unit ( http://www.seicane.com/8-8-inch-tou...sd-3g-wifi-steering-wheel-control-video-1080p )

My unit has a resolution of 1280x480. Version 1.25 has two choices for resolution, and neither is 1280x480. Part of the screen is always blank, and I have to navigate with a mouse because the touchpad and screen are now way out of sync . . . : (

Does anyone know if there's a stable version of IQ Navi that can be set to 1280x480? If so, do you happen to have a link to it?

Thanks a bunch!

Patrick
[Android Head-Units] dud89:
Never seem on with that resolution. You might be able to get the original firmware from your seller and re-flash that. Should not affect the new partitions but you might want to ask the firmware developer first.

Has anyone had wifi problems with their unit? I received mine this week but the wifi is not turning on. I tried factory reset but it didnt help. I also tried connecting my mini usb wifi stick to the usb cable on the unit but it doesn't seem to work either. I also tried to share internet from my phone via bluetooth but no luck with that either. So currently I'm unable to connect to internet with this unit :mad: Any suggestions?

Thanks!

Sorry to state that manufacturer support for these units is non-existent. The Bluetooth quit working on mine and have been trying unsuccessfully to get the OEM firmware without luck. I've tried to contact Tonghai Create Electronics via email in numerous occasions with no answer. Also, their Service and Support page does not have any files in the downloads section. You are welcome to try though. If you are going to use these units 'as they ship', they work OK but if you are looking for a customizable unit, I definitely would not recommend them.

Okay, I have another question about the reversing camera now. Every time I reverse the screen goes black (I don't have the camera connected, only wire hanging free/taped) and after that android restarts. Is it normal that android restarts (full boot) every time after backing up or should it switch back to android immediately? This sounds a bit like wiring issue but I want to make sure before ripping the dash apart again.

IQ Navi V1.3.X supports 1280x480

look at the iqnavi release page

I can't post links here so just google "firmware-an21" and you will find it

google translate is your friend.

note that you would have to dish out some money to get this version, but this firmware is so much better than the manufacturer's, it's worth the extra 25$
[Android Head-Units] pfarley11:
Thanks. I have IQ Navi loaded now (version 1.25). However, the update version does not increase the internal memory as the flash version does (update by PC, kernel and all). From what I understand, the flash version would increase internal memory to 6GB (from 1.5GB) by reallocation - to give more room for apps.. The problem is that the flash version of 1.25 does not yet support 1280x480 resolution. So, I currently have all the features of IQ Navi(which is great), except for the increased internal memory. So, I'm having to use Apps2SD to get a lot of my apps on there. This works, but it slows down the device a lot, as compared to just having more internal memory.

I had heard that RedMod was working on a 1280x480 flash version, but I'm not sure if it's complete yet or where to download it. If it's not complete, I was wondering if anyone knows an ETA, etc.

Thanks!

Long time I didn't post here

I have the HU described here. All was working fine (except the FM radio).

2 weeks ago Android started to boot really slow (more than 1 minute) I'm pretty sure that is Android because the native audio plays before the complete boot process is over (Android logo still on the screen)

What 's happen? do we have to apply a kind of maintenance to clean cache for speeding up the HU at boot? Once the HU is completely started the speed is acceptable and apps are working as expected. The issue is only the lag during boot

I've already done a factory reset, no improvement seen.

Any tips would be really appreciated.

Hi, i have quad core r16 head unit and i'm using iqnavi software 0.1.25. Everything is working great but when i go to settings and to About screen i see MCU version 5.3.18..... and if i go to Extra settings/Car model there is bunch of cars but MCU version is 5.3.17.... Does anyone knows why i have two different versions of MCU?

I'm new to android head units and new to this forum. I need help badly. I have an android head unit. All was well until this morning I was browsing all the settings and somehow managed to change to resolution. It is a 800x480 unit and I accidentally changed it to 1024x600 I think.... Anyway, now the operating system and all the apps are larger what the screen provides so I can't see all info. I tried to go back into those settings and change it, but like I said, the OS is too big so I can't get to that option. I also can't get to the factory reset option

So I bought a Tonghai unit from Seicane for my Porsche Cayenne S and it shipped with Android 6. The iPod app won't launch, nor will the DAB+ app they provided connect to the device.

Car Selection Extra Settings

In my head unit im not able to select a car type in the car selection menu (extra settings). There are no car listed in the section. Is there a way to fix this? I have installed the IQ Navi Firmware 1.25
[Android Head-Units] wigglitz:
Why are you trying to change your car type? Pretty sure the one it sets itself to is the default/universal setting.
[Android Head-Units] aukev1971:
Im not able to select any car type because there are no cars listed. I guess this is the reason why the car settings app is not working. When I start the car settings app the response of the app is no car settings..... So i don't see any information about the car. Im driving a BMW E46.

Hi Guys,

I have IQ Navi 1.25 installed (flashed via Phoenix).

Do you know if there's any way to save a backup image via a recovery such as TWRP or some other custom recovery? It would be a lot more useful for my purposes than doing a Titanium backup, etc.

Thanks!

^

I am also looking for a way to make full ROM backups to easily restore like TWRP-ish.

I know you can save the systems partitions based from the guide in the OP, but I haven't found a way to restore them. Not sure if it would work on custom firmware the same way if possible also.

Sigh... This isn't good. For some reason the buttons on the side of my Tonghai with Android 6.0.1 stopped working, none of the built in apps work (radio, bluetooth, EQ) and I can't access the Extra Settings menu in Car Settings (just crashes back out to Settings). The MCU version is now reporting as "Unknown" too. All this just from installing Google Now launcher it seems?!?

Factory Reset option doesn't seem to do a factory reset. I'm feeling pretty ordinary at this point.... Anyone got any ideas?

Can't even seem to do anything in recovery mode as the volume up/down and home buttons don't respond (there aren't any physical buttons on this unit)
