I found this problem first on [MENTION=391948]Zaphod Beeblebrox[/MENTION] Rom (based on 1.0.9). MCU 34.

Never had such expression "Mobile network not available" before. Workaround for all previous issues was to make call from phone. After that calling was able from HU too.

But this doesn't work now. Seems will have to flash to other or newer rom.

I still haven't found a way to select the option to use internet connection over bluetooth automatically. I don't have to make any changes on my phone and they re-pair just fine every time.. I only have to open BT devices and select the options next to my phone on the stereo and check the internet box, then I'm online instantly. But I have to manually check that each and every time I get in my vehicle. From speedtests I've seen online you get close to 2Mb over BT tether.

I need help.

Somebody faced with a problem off the SD card. I have almost all music applications after 2-3 tracks are disabled. The system displays a message - Disable SD card. Tested several cards - the same mistake. Navi applications work fine - maps are available on the SD card.

This situation is repeated on all firmware versions and it is only in music applications.
[Android Head-Units] Duck Dodgers:
What is the make/model/size of SD card and the other ones tested?
[Android Head-Units] Bokomaru:
I uploaded a flashable version here:

http://xfer.aokp.co/get.php?p=zaphod/nu3001/xdAuto-1.1.6b2-working.zip

Still trying to figure out what is causing the weirdness with the image flashable via rkbatchtool.

From what I can tell there is no difference between the upgrade and restore method on that tool. The images created tell the recovery what to do and the default is "--wipe_all". We could make an image flashable with that tool that doesn't wipe, but I think the best choice is to always assume that the rockchip images are for a complete wipe and the recovery flashable images are for upgrades.

Got my 8 inch today! DHL is super fast! Hong Kong to MN in a day and a half!!!!! Little confused though. On its wire harness there are two yellow B+ wires. Am I to splice these together? Why are there two power wires in? Is it because they're not that thick of guage? Thanks
[Android Head-Units] 1WindManic:
Hi, splice them together.

I had some time to play with my unit. Firstly, the lcd brightnes is low. Is there a way to boost it? I don't want to tear my box for now.

Secondly, my fm receiver is has poor reception, so i ordered preamp module, hope it helps.

Anyone here using mate display foil?

thank you very much, I was not sure you can install.

you know if the updates in mcu, of the nu3001 also serve for the nu5002 ??
[Android Head-Units] Bokomaru:
Yes it appears that they all use the same MCU code. A couple versions back there were some new strings added to the MCU file that indicated different hardware versions.

I really wish this information was sent over to the Android box, if anyone has seen it anywhere please let me know.
[Android Head-Units] Danny.69:
Thanks, then II will update the mcu to v37, and install 1.1.4 rom tuatara

Hi guys,

It's been a long time.

As requested before I have purchased this remote http://www.amazon.com/Satechi%C2%AE-Bluetooth-Button-iPhone-Samsung/dp/B00RM75NL0/ref=sr_1_1?ie=UTF8&qid=1431373288&sr=8-1&keywords=satechi+bluetooth+buttons

[IMG="image"]http://www.jebiga.com/wp-content/uploads/2015/02/SATECHI-BLUETOOTH-BUTTON-SERIES-1024x450.jpg[/IMG]

It has been working great and in a hot car it is still functioning. I no longer need to use the buttons on my unit itself.

Also anyone wanting to auto start wifi tether on your phone without taking it out and enabling wifi tether or without paying and figuring out how to use tasker, get this app. This app will detect bluetooth connection then it will auto start wifi tether and it will also end tethering as soon as you disconnect from that particular bluetooth. Works well.

Hi everyone,

Hope i am placing this in the right thread. Im looking for a good car stereo and this company seems to be the only one to do decent powered products (quad core 2gb ram, 1024*600 screen). Unfortunately the one mentioned in the beginning of this thread is without buttons. The ones i could find with actual knobs are either dual boot or for VW... I have a toyota hilux... Are there any universal 'knobby' stereos or do you think it would be possible to root the dual boot one and install just Android? :P

Thanks :)
[Android Head-Units] Bokomaru:
Now that is cool. Might have to get one just to play with
[Android Head-Units] Zaphod-Beeblebrox:
I've largely used wifi tether for this very reason. Your post made me decide to tackle it over bluetooth again and Tasker along with secure settings plugin (https://play.google.com/store/apps/details?id=com.intangibleobject.securesettings.plugin) seems to do the trick for me.

I have NO tasker style apps running on the phone. I simply have CM12.1 (LG G2) and have turned on bluetooth tethering hotspot and leave it on.

On the HU I have Tasker set for a 'BT NEAR' state (looking for the Phone BT ID). When State is true, Secure Settings task is to 'connect' to G2 BT ID. Rode around most of the day, and after every stop/start it connected back up just fine.

How are the volume buttons working? Bonovo's Volume intents are a little different from the standard Android volume keys. Wondering if volume keys are changing master volume, or just android volume?
[Android Head-Units] wacko37:
On the note of Bonovo's Volume, I am having problems with no sound on my revsering camera (av inputs)

I have tested the source and it works right until the Headunit and all is ok but still no sound when plugged in. I have also tried mute and unmute in the mcu app.

[MENTION=2190016]Zaphod-Beeblebrox[/MENTION] So I guessing based on the comment above maybe it's the master volume, if so how is this adjusted on the NU5002S?

Thanks
[Android Head-Units] Bokomaru:
I would strongly suspect that when in reverse it does a complete switch to the reverse camera input without any audio, all of that should happen on the HU so the android box probably can't mess with it. Though there are some things to try, I still haven't installed my unit yet so I can try a couple things out tonight or tomorrow.
[Android Head-Units] wacko37:
That would be great thanks
[Android Head-Units] ElfinJNoty:
There is a setting in the MCU app that will disable or enable the sound when in reverse. The translation is weird... But it does it
[Android Head-Units] Bokomaru:
Oh that's the "Whether Astern Mute" right? Have to update that to be more clear. "Mute audio when in reverse" might be better.

Edit: just verified that when "Whether Astern Mute" is not checked the audio is not muted. Going to update the community rom string to make it more obvious
[Android Head-Units] blacklistedcard:
V40 is out. Seems to run fine
[Android Head-Units] wacko37:
Yeah I have also tried the "Whether Astern Mute" but I still have no audio.

I have plugged the microphone cable from the camera ( just b4 the Headunit ) into my laptop using an rca to 2.5mm jack converter and the sound is there no problems.

So it has to be the Headunit or the settings.

I am currently running Tuatara 1.1.4.2 rom and v40 mcu, recently update from v33 the other day to see if it would fix the problem.

Any ideas? Would it be worth trying another rom?
[Android Head-Units] Bokomaru:
I don't think a different ROM will make a difference since the code is all pretty much the same at this point. I have a feeling there is a misunderstanding somewhere. The Reverse only has a video input, but the AV1 and AV2 has both video and audio input.
[Android Head-Units] mos33y:
What roms have you used which have not had the "Mobile network not available"? I have used Zap's (various builds) as well as Taumour's rom all having this issue.
[Android Head-Units] wacko37:
Ahhhhh..... now that's disappointing.

Is there any way to use that same audio input with the reversing camera or force AV1 or 2 to appear when in reverse?

Also thanks for all your help and input throughout the forum. Deeply appreciated by all im sure.
[Android Head-Units] Sterg1967:
Yes I update the MCU too,I copied in sd card hex and bin files and I used RKBatchtool v1.6 and restore not upgade.
[Android Head-Units] renedis:
After copying to SDcard, did you opened up the MCU app and searched for an update. And after that, installed it?

If you are still in a bootloop, please revert to version 10.0.8 and update the MCU first to version V26.

Reverting to 10.0.8 is done in the same ways as updating for version 10.0.9
[Android Head-Units] Sterg1967:
yes I used restore not upgrade,and you i think that in page 33 had mention that you have the same problem and you down grade to 1.08 am I wrong?

---------- Post added at 11:29 PM ---------- Previous post was at 11:14 PM ----------

Yes after copying to sd i opened up the MCU app and searced for an update and after i installed it then disconnect android box and connected it to pc and made the restore.After that when playing for example the radio after 2-3 minutes the device turn off and i must touch the hu to open again.How can i revert to version 10.0.8 and V26 where can i find it?
[Android Head-Units] red13dotnet:
So it turns off then you have to touch the h/u to turn it on again? Is your screen just going to sleep? default screen sleep time is 2 min i believe. Try setting that to never under Settings : Display.

---------- Post added at 04:38 PM ---------- Previous post was at 04:34 PM ----------

I'll make never sleep the default on the next release, 1.0.9 stock has a sleep of 2 minutes that got carried over.
[Android Head-Units] priusfan:
this is not a bootloop...

yes the sleeping delay is 2 minutes....

I changed it to "never"

[Android Head-Units] red13dotnet:
So I'm sneaking some time on someone else's computer to try building the whole system from source unchanged..so that's compiling merrily as we speak. Just want to make sure that it works as is and flashes normally, then I can start looking into changes. I am seriously considering accepting voluntary donations towards a bare bones headless build server. If I ever get one going we could switch to using it as our primary git server too.
[Android Head-Units] usafle:
My unit arrived. Heading to my installer shop tomorrow at 10am. Any advice/tips/suggestions?

I was under the (incorrect) assumption that the faceplate came off the unit so you could update it via adb etc. But, it doesn't appear so. How are you all flashing/updating? The manual doesn't really say much at all.
[Android Head-Units] red13dotnet:
If you got what we got, the NU3001, then there is a small black box in the smaller white box. That's the actual android box.
[Android Head-Units] usafle:
Yes. The small black box is in the packaging
[Android Head-Units] red13dotnet:
That's how everyone is updating. Depending on the requirements of the ROM, you can flash the box using rkbatchtool by itself at your computer but you'll need a 5v power adapter. You can flash some Roms and you must flash the MCU using an SD card plugged in the android box while its all connected to the head unit. As far as install gotchas, most of those that have been encountered so far are in the thread. I'd go back through it to see if there is anything to watch out for.

Thank you for advice. Device reboot solve my problem. Disabling automatic time correction was not needed. Enough to change time settings at clock application and make reboot (long pressing to power button to switch off).

Anyone have do to work TomTom navigation on this device? I was tried different versions, but have an error - no GPS signal - at same time google-maps, gps test, torque and other application works with gps module graceful. I'm sad :(
[Android Head-Units] Sterg1967:
I use Sygic,i have bought the program this not crack,but as i can see in cold start,for example in the morning,wants 3-4 minutes to lock gps signal,in hot start almost immediately.I doubt about the sensitivity of this gps,as with other gps receivers i have in seconds gps signal in cold start.
[Android Head-Units] alaninsitges:
I wonder if the source would be useful in getting to working a Lollipop version? I'm far from an expert in this stuff but as I understand it with yesterday's AOSP release we should be able to build a working base system and the rest will be drivers, SW to communicate with the MCU, etc., all of which we have the source for and which may or may not be able to compile for 5.0 without (m)any changes.

I don't think so that the power supply of the android black box is 5v,it is 12v dc 1-2 ampere,I tell that because mine works with 12v dc not 5v.first I tried with 5v dc but nothing green light was off,then i sent email to spain seller and told me the specifications of the power supply 12v dc 1-2 ampere would be ok and worked fine.

I have TomTom Western Europe working on my unit. (Version 1.3.2 - 1534341)

Here are the instructions:

Only for Android 4.4.2 KITKAT !!!

Copy the files on your external SD card.

1). Copy the *.apk to your internal H/U memory

2). Install the *.apk

3). Start tomtom

You will get an error with something like this: "Could not make contact with TomTom"

4). Close the app, and reboot your device

5). After the reboot, navigate in ES explorer to the location where you copied the files to on your external SDcard

6). Cut the folder "files" and ". Metadata.xml" files to:

"/sdcard / android / data / com.tomtom.(land) / files / files /" (Yes, it needs to be placed on the internal memory of 5/6GB)

8). Start the app by pressing the icon and see if it works!
[Android Head-Units] ilcazzo:
Thanks I'm already saw this instruction..

I've no problems with maps or application content - maps are shown normal. Problem with GPS signal - application cannot detect position - message said that is no GPS signal.
[Android Head-Units] renedis:
I have no problem with this, sorry, can't help you with that.
[Android Head-Units] wacko37:
Wish I had your knowledge or even half of it. Won't even know where or how to start.

I have a large vehicle and you would always here kids before you see them ? but not to worry at least I can see what's going on back there anyhow.

Thanks again
[Android Head-Units] Bokomaru:
Some further testing and by unchecking the "AV-IN" config option (which I've already renamed to "Switch to Rear Camera when in Reverse") the same keycode is sent over when connecting the reverse wire.

So in theory someone code hook in and use keycode 348 (unless it is used for something else as well that I haven't realized) and have that toggle some other action.

I still need to go through and document all the serial commands sent across and then start probing the other possibilities to see what happens, there could be some other interesting things we could do.
[Android Head-Units] spoks:
Almost every stock rom and Tuartara's rom, but this sentence I first got on Zap's second(?) build which I am using now.

I suspect, that there could be something that "stays" from some rom flash even after other reflash. I do not know how it would be, but, for example, there were some ROM and MCU versions where was possibility to change shutdown times.

After flashing these, the default shutdown time was 0 min (not 2 hours) and if it stays untouched, then on next new rom flash shutdown time remain 0 min. and you wouldn't be able to change it because not such option in new rom.

The newest ROM b1 has the standby options and they work fine.

[Android Head-Units] Bokomaru:
There was an issue with the b1 app causing a few things not to work. If you use TWRP to update to the b2 version it will resolve the issue.

Some people have been having an issue using the rockchip flash tool to update to b2, I'm still digging into the issue. I actually need someone who has this issue to take a full image of their system and send it to me (about 4gb compressed)

I have not heard of anyone having an issue with v40 at all.
[Android Head-Units] NU5002S:
I installed 1.1.6b as an update on top of Tautara 1.1.4,

At first the update.zip file was not found because /external_sd/ was renamed to /externalsd/ or something

Has anyone else had this disparity? I believe it may be getting in the way of my MCU v40 update because I have the updatemcu.bin and the hex file on my externalSD but the "Update Setting" app doesn't see it.

Does anyone know how I can fix this?
[Android Head-Units] Bokomaru:
Under TWRP the external card will show up as /external_sd

and internal is /internal_sd

Once the ROM is running it will show up again as /mnt/external_sd and /mnt/internal_sd

I'd have to double check but I believe the update rom app is only looking on the internal card for updatemcu.bin
[Android Head-Units] NU5002S:
Oh! I will try to move the update to the internal_SD and if that doesn't work I will reflash everything with rkbatchtool. I feel a clean wipe might help me with any issues I've been having. Thank you for the tip boko!
[Android Head-Units] Bokomaru:
Well it looks like the Bonovo folks did some cool stuff and they made it possible for this to work right now, though you will likely need to use an external app (like Tasker).

I just tested it out and it works how you would like. I didn't set the whole part of just the proof of concept, you would need to store a variable to know when to kill the app vs start it up but it's not a difficult thing to do in Tasker.

Here is how I set it up.

Disable "AV-IN" and "Astern Mute" in the MCU control settings page (whatever thats called now).

Under tasker setup an action on the intent 'android.intent.action.KEYCODE_BONOVO_LIGHTSTATE' to fire up the AVIN app.

Have your Camera and audio hooked to the AVIN setup and you are golden. Just another awesome example of the cool stuff you can do with Tasker

---------- Post added at 10:11 AM ---------- Previous post was at 10:03 AM ----------

Looking at the code it looks like it should work with either internal or external so that shouldn't be an issue.
[Android Head-Units] Duck Dodgers:
I've just mailed the developer - looks perfect but as I'm going to be using EE's Buzzard 2 (http://shop.ee.co.uk/dongles/pay-monthly-mobile-broadband/buzzard-2-from-ee/details), will not be emitting Bluetooth signal to "notify" the tether.

This may work after initial pairing and then plugging in the Buzzard into the cigarette lighter to "auto pair"

It will also power the USB hub :)
[Android Head-Units] Zaphod-Beeblebrox:
you shouldn't need any app. That's basically a WiFi hotspot. Once you put in WiFi credentials on the HU, it'll auto connect.
[Android Head-Units] Duck Dodgers:
Thanks Zaph - I thought it would have the same issue as the auto connect with tethering!!! Never used a wifi dongle like his before so did not know what to expect.

xdAuto ROM 1.1.6b2

1.1.6b2 has been uploaded for a few days now. This has been tested with MCU v40 and configurable standby timer does work (as long as MCU version is >= v37)

Recovery flashable zip

RKBatchTool flashable img

Some people have had issues flashing with RKBatchTool and I was hoping to resolve those before releasing another version but I haven't been able to reproduce the issue to troubleshoot it. If someone does run into this, please send me a PM for some steps to create an exact image of the internal flash so I can inspect and see what is actually going on. I would like to get that issue resolved before the next version is released.

1.1.6b2: May 9th 2015

Change ROM name from CarpadCE to xdAuto

Added Apollo music player

Updated Radio code to 1.1.6 with Zaphod's ducking

Fixed Audio and other issues due to /etc not being setup properly

Modify TWRP to accept '--wipe_all'

---------- Post added at 11:18 PM ---------- Previous post was at 11:04 PM ----------

Looks like my earlier post about using intent android.intent.action.KEYCODE_BONOVO_LIGHTSTATE was a bit off. This keypress/intent is sent when the illumination wire and the reverse wire get power. So what I posted earlier will fire up AVIN when in reverse or when the lights are turned on.

Will keep looking for a viable option. Might be useful to request an update to the MCU that sends a keycode specific to reverse.

edit: with the IOCTL_HANDLE_MCU_REVERSE_STATUS we can definitely query whether or not reverse is triggered, so we are back to square one with it. We can definitely tell from the android box if reverse is on so it is workable. It would be easier to have a keypress to trigger it, but we could have something running that checks if it is on and switches the mode based on that.

another edit: I see now where the keypress is being triggered (in the kernel) so we definitely can come up with our own keypress/intent for this.
