Geat, thanks, good to know there is a colour choice.

I m sure you can get an app that allows you to make your own widgets, unsure if they ll work with this set up though, so yeah, external DVB T is the way to go. Still in the process of reading the whole thread, not got to the bit about usb tuners yet :)

Thanks for the advice about Torque, but I agree with donaldta - cant see the point of using bluetooth for OBD when the OBD port is only a meter away and the headunit and usb port are never going to be moved, bluetooth was designed for portability and portability isnt needed in this case, so as usb is faster and better quality, why use bluetooth ?

I think torque via usb only works with kernels above 3.0.0 though, havent seen any mention of the kernel this unit uses yet.
[Android Head-Units] donaldta:
Yes, you can. Something I forgot to mention. If your SWC uses voltages over 6v then I would highly recommend that you involve a voltage divider. Although it is not very common in newer cars, some cars range their SWC signaling up to 12 volts. Sometimes more when the alternator is charging the battery. Depending on the SWC adapter's tolerance, high voltages can end up frying it. Most of the ones that I've worked with can only deal with voltages between 0.5 to 5.0 volts. That's why I always recommend using a multimeter to examine how it works if you do not know exactly how it is controlled.

I know this has already been answered but let me elaborate. ADW Launcher is a home screen replacement for Android written by

eb. I don't know why but it seems to have taken off in the head unit space. Sometimes, I wonder if it is because it is "that" good or if people are hesitant to explore other options. Don't feel that you're confined to using ADW because everyone else is doing it. I suggest that you explore your options and find one that best suits you. There are plenty of other Android launchers that you can use; Action Launcher, Aviate, Buzz Launcher,dodol launche,Everything Home, Espier, Go Launcher EX, Nova Launcher, Smart Launcher, and Themer are some of the ones I've tried. (Personally, I use Next Launcher since I got it free from one of those "give-a-way" days.)
[Android Head-Units] donaldta:
It is not really the kernel version that matters, and I'm not sure if you're confusing the underlying Linux Kernel with the Android Operating System version. While USB Host was officially released in Honeycomb (Android 3.1 - API level 15) that doesn't mean it cannot be used in earlier versions. There are other head units with earlier versions; like the Gingerbread (2.3) Ca-Fi units, that can use the USB to ODB cables as well. Actually, Torque Pro has specific checks (/etc/carit_version2) whether or not it is running on a Ca-Fi unit and will read the ODB information directly from the Linux devlinks.

The important property is if the kernel supports USB Host and if the serial to USB drivers are present to support your cable. That's because the datalink between the USB and the ODB microchip is a simple serial adapter. Torque Pro does comes with /data/data/org.prowl.torque/lib/libserial_port.so library to support FTDI and Prolific Serial to USB drivers for the newer Android 3.1+ with the USB Host APIs. The problem; however, are the advertisers of the USB to ODB cables are quick to specify the programmed microcontroller (ELM327) but not so much the brand of USB to Serial adapter used in the cable.

Yes I am in Massachusetts. The seller was bestdream_gift on ebay. I got the android 4.1 unit with two physical knobs. (offered $350 and was accepted, may have even accepted a lower offer)
[Android Head-Units] typos1:
Sorry, I was quoting from memory, just looked at the notes on Torque Pro and its the Android version that it mentions (has to be 4.0 and above), not the kernel version. I emailed the dev a few months ago as I was having trouble connecting with usb and he said the lead had to be FTDI compliant as well.
[Android Head-Units] djblaze852002:
Something I noticed... When you're in the "Phone" (Bluetooth App) and you see a device like a phone... You can long press it and a menu pops up showing an option for "OBD". I wonder what thats all about...

Also does anyone know what the Color app is all about?
[Android Head-Units] pgarrity18:
You said you had trouble with connecting to USB. Was that with one of these unbranded units? I just ordered the scantool.net OBD USB cable (non-bluetooth) but it has not arrived yet.
[Android Head-Units] donaldta:
Yeah with all due respect to Ian Hawkins, sometimes I wonder about his ability to document and check facts. Let me give you an example, below is a screenshot of Torque Pro running on my Nexus 4 running KitKat (Android 4.4.2 - API Level 19). Mind you, I am running a stock kernel which does not support USB Host.

While the first part is correct and reflects my device, the middle part is a wee bit misleading. First of all, Android 4.0 is Ice Cream Sandwich not Honeycomb. Honeycomb encompasses Android 3.0 to 3.2 (API levels 11, 12 and 13 respectively) and as I written earlier, the USB Host was introduced in 3.1 (API 12). Of course, it is not entirely, uncommon for manufacturers to backport features from a newer API to an older one.

Now, take a look at the same screen on my Asteroid Smart running Gingerbread (Android 2.3.7 - API Level 10).

Now magically, Torque Pro supports USB with Gingerbread contrary to the what was displayed on the Nexus. In fact, if you check the the connection type. I have the following options:

The amusing part of the choices is that my USB ODB cable isn't even plugged into it. The USB0 is the external GPS unit and USB1 is a barometer sensor. Of course, someone whom knows the difference will point out that the "USB" option is using the the USB Host API provided by the Java layer where as the TTY USB# options are provided by the Linux layer. Therefore the notes shown between the two devices are somewhat device specific.

I tried to update my VW unit today, but something doesn't work.

I put all the update files onto my sdcard (extracted) and then tapped System Update. The unit reboots, it says Update Started and then immediately Update End... I tried 2.6.60, 2.6.60-2 and 2.6.62. Currently I'm on 2.6.60.

Did I miss something? Thanks for your help!

Edit: Should the sd card be empty (except the update files)?

Theoretically it should be possible as long as a few variables are in the programming.

Because your then connecting using the dongle and not the bc5 module. It's like if we could hook a digital tv tuner to our usb and use that for ota digital tv

I have not had good luck with 2.8.6, however even worse luck when flashing 4 files.

I would do a full restore to stock

And then update to 2.8.6 with this https://yadi.sk/d/tbaxJYL9cJjKK/Firmware

The problem ... I haven't been able to properly root 2.8.6 , though I will admit it's only been installed for about 10 minutes, I probably didn't reboot the unit for root. Was to impatiant to try a different file explorer.

I installed 2.8.7 for the newest whatever it may be experience. I'll attempt to get the radio app installed from 2.8.6 but, my antenna isn't even connected so it's a lost cause for me.

2.8.6 installation with the boot image from the 2.8.7 files should get you root.

USB Storage Permissions error

I have recently had problems which required me to factory reset my head unit and reflash the firmware. I now have issues with read only permissions affecting my USB storage (Internal SD). Applications are failing to install or save settings as they don't have permission to write to the storage.

Does anyone know how I can either reformat the entire internal storage on my head unit or alternatively how I can force write permissions on the internal storage?

Also, does anyone have the latest full firmware ie 2.8.7 for this device? also would like the latest MCU firmware updates too

Cheers :confused:

thank's for your reply.

is not exactly like that of your link,

frontally is equal, but behind is very different,

also has the DVB-T

( i can't send a link )

if you tell me how I can get MCU version and system version,

I read them and send them to you.

// Now for me is creating a new problem.

sometimes you start another rom, and many things do not work,

I have to press the reset button and the system will reboot with the ROM that works.

for this reason, if you tell me what I read, I do them and sent.

you tell me that my stereo has an MCU - AN-21U?

for this MCU I read that I have to use the rom with this title

"Tonghai Create AN-21 U"?

is that my stereo has the DVB-T

is there any benefit of updating the MCU and should you update ur MCU along with the software firmware upgrade every time?

I am running 2.8.7 and my MCU is 4.39-1-10-20210101

thanks in advance:

[Android Head-Units] shadowmike:
If you have a proper matching mcu to update then the only benefit is a properly working radio

Perfect example. At one point a system update came out and the mcu for some units was not released. We tried a mcu and it broke either Bluetooth or the knobs.

Volume down was up and volume up was down...

The only way of fixing this at the time was using an updated mcu that had the programming for the knob rotation settings.

Some people had to wait a few updates because the mcus for their unit was not being updated.

My rule of thumb for mcu is just like Android phone firmware.

Unless it is absolutely needed to allow the radio to be 100% functional. I will not update it.

My phones WiFi will not work until I update my firmware because 4.4.4 isn't compatible with my 4.4.3 firmware... I don't use WiFi so I haven't updated it yet.

But the mcu is what runs the radio, so technically any update would only help the radio, but it can be a bad thing if you don't use the right file

[Android Head-Units] wanxu:
Well, as I am on 2.8.2, I can't use Tomtom. I also can't use online soft as I am offline in the car. In my opinion:

Sygic is the best in terms of smoothness. There are 2 versions though, old (14.3) and new (14.6) with different interfaces.

I would use the new one because is beautiful, but in my screen (8 inches) everything is really small. Check this out:

[IMG="14.6"]http://i.imgur.com/yFqgg49.png?[/IMG]

[IMG="14.3"]http://img11.nnm.me/6/a/3/5/3/b2f9966deb89af9c185a277a0ec.png[/IMG]

These are internet screens. The ratio isn't the same with big screen, so the text is the same size and buttons are so little...

Igo , for me, is far more complete and configurable (there are bunch of skins available), but it's less cool, and is slower than Sygic.

Right now I am using both of them, haven' decided which one will be my daily option. Others like Garmin or Navigon, I don't like them.

in sygic I don't know how to edit or add red light cameras. I have sygic 14.6.6 on my android phone it look ok but it seem hard to enter directions like the 14.5.

Igo have lots of addons that make it great, like shins and voices. also in IGO manually set police area and camera areas. also you can use tomtom maps in ogo.

That behaviour is MCU related and typical for "wrong mcu version for your mcu board".

If you noted the version of your original MCU somewhere, you can track the corresponding correct mcu for your hardware. If not ..... you'll have to experiment. Carefully. :)

It only took me 3 months or so to rectify a bad MCU because no correct MCU was available at that time.

hey guys,

its me again. The WiFi problem is still not fixed so I bought a 4G Dongle. It does not connect itself so I wanted to give PPP Widget 2 a chance. Turns out it needs root access so I tried rooting my device.

I am on 2.7.38 and I tried to root it with the Baidu App from the wiki and several Super User apps from the Play Store. They both have this "SU binary needs update". SuperSU can not finish the update of the binary, Superuser von Clockwork can. Checked with the app "Rootchecker" I could confirm that my device was rooted. However, after every restart, the root ability is lost. Also, sometimes I cant even get it in first place?!

What can I do to permanently get root to use PPP 2 Widget?

Bests,

btw: I don't really want to flash to 2.8.6 since I feel there are mixed feelings about this version here and besides internet my device runs good so far...

If you flash new system (2.8.6 or whatever) the MCU doesn't update itself. Then, you can update it from settings/extra settings/car model, and selecting your car model (or flashing it).
