I like the new EQ app & the new radio app too.... I just can't get the radio to store presets & the EQ always defaults after a power cycle.

BTW. my MCU version is 4.2.15-1-20-2101 on system 2.7.11

Bluetooth works, volume knob works (clockwise makes it louder & press for mute) I hope I was helpful & didn't steer you in the wrong direction
[Android Head-Units] fcortes626:
it working right now. i think mine is 1-10-201 or it might be the same one you have. but i didnt choose a model because thats how i bricked my last one so aslong as it is working im ok with what i have. my presets seem to have saved after updating. i will check and make sure the eq doesnt reset.

This message is shown by the com.tw.service_a5a4.apk... BTW, this error message will also appear if you try to mod the service apk.

Nevertheless, the error message is only a simple layout file in this APK. So if everything is working and it's only about that persisting error message, you could decompile the service apk, set the LinearLayout's visibility of the error message to "gone" (in com.tw.service_a5a4\res\layout\ui.xml) and then pack again. If you do so, the error message should disappear...

[Android Head-Units] jpapadami:
So what is the latest firmware and MCU anyway? I know that there are 3 new firmwares. Some are legit while others are possible fakes. AFAIK, there is

1. Android 4.1.1 with firmware 2.7.11

2. Android 4.2.2 with firmware 2.7.11

3. Android 4.2.2 with firmware 2.7.22

I've installed Android 4.2.2 with firmware 2.7.22 and it has MCU version starting with 4.3.1. I don't know if there are any improvements to the MCU as I don't have any issues and I don't see any changes in the firmware. Only real change is that the EQ, BT, Radio, Music player, etc... stock apps are now with the red theme and not blue.

Who's using what firmware/MCU and which one is recommended as the most recent official update?
[Android Head-Units] Miwer:
I have also updated to the 2.7.11 - and updated the MCU to 4.2.15-1-10-2101

I haven't tested storing radio presets, but I also have the problem with the EQ resetting to default (even though the sliders are where I set them). This is not only during power cycle, but every time I start the radio app.

I didn't have this problem with MCU version 4.2.5

I think I might try to downgrade to 4.2.13 as Skratchuk mentioned in post #3752

Although I think my AF is working now, because I have seen my radio switching between frequencies on the same channel. But I think it's buggy at best, because sometimes my radio just suddenly start scanning forth or back, and I need to select the station I want to hear again. Wierd.

TA is still not working properly for me. The radio still don't switch to the local traffic channel when they broadcast an announcement.

On another note: I'm trying to decode how the MCU update works, and so far I have discovered how the MCU filenames are "translated" into car model, features and such in the model choose dialog. I just need to make sure I get it right before I post anything. [MENTION=1915855]KID52[/MENTION] are you interested in such information on the Wiki?
[Android Head-Units] Skratchuk:
Using 4.2.13 did sort the eq problem out but then started a problem with the sound not working on android apps only stock apps.

4.3.1.1 Does seem good BUT yes there is that annoying problem with eq with radio i have managed to store radio stations (was not easy at first) by keeping your finger on the station name displayed and dragging it to a preset.

I s there anyway to edit eq for radio presets manually?

About Blutooth OBD

I bought mine from Aliexpress. When I told them I wanted to use it with OBDII Blutooth, they told me they would have to wait 4 days to send the unit, because they had to install some BT hardware module to make the BT ODB-connectable.

I have recieved it now, and testet it, it connects to BT OBD22 (a cheap ELM327) fine, using it with torque with no problems.

I connect it by going into "phone", clicking the search-icon and/or the list icon above it,then my ELM327-device shows up, I longpress it, you can then select "OK", "OBD" or "PHONE", i click OBD, and thats it, it now connects automatically in the background whenever i turn on my unit, and BT for phone music with e.g. a phone at the same time works aswell, so it seems to handle multiple BT-connections with no problems.

I bought my unit here (but I had to ask spesifically for them to add the hardware-BT module to support OBD, this is free, no extra cost):

http://www.aliexpress.com/item/2014...-Dvd-Player-Pc-Gps-Navigation/1696603095.html

It came with FW 2.7.9 on it, works very good right out of the box, with audio stock vs 3rd party, radio saving, bt, eq, 100's of led-colors everything is problemfree so much that i'm staying away from upgrading anything on the MCU / FW.

It rooted fine with the method described on page 1 in this thread, with ADB via WIFI from a Windows PC. (the ADB via WIFI was necessary, just booting then clicking option 2 was not enough).

Only thing other that root i've done is run Sygic on it, since its much nicer and smoother (faster) graphics than IGO/primo, and installed "Screen Filter" which removes the white-burnout problem on the LCD-screen without making it darker for other than burned out whites. Just remember to disable "Screen Filter" when installing things from outside Play Store, since Android has an overlay-protection from hitting "Install" when anything is running as overlay over everything else. Other than that Screen Filter is very good, and does not slow down the unit at all.

Running Screen Filter with the "black" option at 40-50% will completaly get rid of the white-burnout problems in play store or other apps with much light backgrounds etc.

In viper, hit menu & scroll to the bottom & select "driver status" and look to see if "processing" say "yes"

Under phone speaker, make sure the top checkbox is checked "enabled"

For Slacker, Pandora, and the radio to utilize the VIPER processing I had to check "Force enable V4A"

I use PowerAmp for my mp3's. In PowerAmp, I had to uncheck "Direct Audio Output" for VIPER to process.

Experiment. Learn. Be a little brave & play with some settings. (at your own risk)

As for the Launcher, I use HD Launcher. I like the new launcher but it STILL does not allow for customization. There are many in the Play Store. Download a few & try a few out. Find one you like.

I experimented with Launchers on my Nexus 7 prior to deciding which one I was gonna install on my Head Unit,

Good Luck!

Have you connected to it via WIFI ADB and done all the commands in the video? I had to do that even though the description says its not needed anymore.Using android terminal did not do it for me, i never got temp-root, so I had to do it the adb-way:

Connect your unit to your wifi network,make sure you have a PC also on it

download the adb and su (have su in same folder as the adb) for windows from the videolink or wiki (so you dont have to install the whole google/android sdk)

find out what IP your unit has on your wifi network (see seetings - wifi - advanced by pressing menu)

make sure you have a folder-link or link to the superuser.apk from this thread on your units homescreen, and memorize where on the screen it is (any other superuser will not work, just the one from this forum)

Click on step 1 in the rooting-app

reboot - will be slooooow, dont touch anything

connect with the adb from your PC to the address of your unit which will now have ADB enabled and then do all the commands from the video exactly (he pauses sometimes when he types, so make sure you see the whole lines he types before doing it yourself)

after doing all in the video - click the superuser.apk to install it, reboot, slowness and blackness will be gone and you are now rooted.

some old default skinned apps

Is there an option that I can find some default apps from before new red skin update?

After updating my unit new red skin looks awful and I'd like to revert its look to older blue-gray skin.

I thought that I could extract apps from older update, but I don't know how to get into those files to look after desired apps

Does anyone have backed up default apps from before v. 2.6.40 and would like to share it here?

Everyone that has been setting up Viper4Android, make SURE you set up the IRS files in the /sdcard/viper4android/kernel folder, change the UI setting the moderate\expert, then enable convolver. From there you can select different impulse responses. Some of them sound horrible, keep looking, there will be on that makes your stereo sound GREAT. I can't believe the different it makes.

Same problem, unit is a few days old, sygic stopped working, and mentioned access to SDCard wont work.

I noted that after this happens I cannot modify the SDCard in any way (ESFile Explorer), however if i unmount it, and remount it, I can then create new folder/file in the SDCard (ESFile Explorer).

Until! I open Sygic again. At which point the SDCard becomes read only again :(

Any ideas?

Question for those using Viper4Android

What settings do you keep your stock equalizer on? I leveled all of mine at 50%. I wish that Viper would completely take over, but it seems like the stock equalizer still has an effect on the system and Viper works "on top" of the stock equalizer.
[Android Head-Units] PsychoMcSatan:
My seller sent me this file after multiple requests for an updated MCU. My unit originally came with 4.1.0-7-10-2501-1, but that version hasn't been included with the last few system images. I'm not sure if my seller just had no idea what I was asking and sent me this, or if perhaps it'll clear out some driver remnants that are messing up my bluetooth with all but that one version of MCU.

In any case, I'll give it a go and see what it accomplishes. Here are the install instructions that came with it. Actually, in rereading the instructions, it sounds like this is a fix for non-booting systems. I think that can also be fixed by flashing the .70 version of the image:

--------------------------------------------------------------

Dear friend,

Here is what we got from the factory. It is only for updating the system, not MCU. But they said that the MCU can be updated inside the radio after the system is updated.

1st step, please download the following compressed file and Decompress it into SD card: (please do not forgot to decompress!!!)

http://betopseller.com/img/8f1149c0-ea4a-11e2-9029-000c29ba27c0.zip

2nd step, please insert the SD card when the radio is stuck in the logo.

3rd, long press in the round button on the top left for around 5 seconds, then the radio will be shut down automatically. Then take away your fingers, and use one finger to LONG press in "Home" button , and then Long press in round button again, (long press the two buttons until there are some codes above the car logo, which shows updating)

Then the radio will be updating automatically.

If you do not understand quite clear, you can download the following video for instructions.

Best regards

To tell you the truth, I haven't touched the stock EQ. I just used the viper EQ to sound good around the stock EQ then saved that EQ setting so I can just load it after I flash a new firmware or something of the sort. That way I don't ever have to mess with it.
[Android Head-Units] MFKinSINY:
VIPER4Android

I don't know why (because it's senseless to me) 50% on all 6 bands is not normalized EQ. Select the "normal" preset & see (I mean "hear") if it sounds more like you expect it to.

Also... Try switching between modes & see if one works better than the other for you (Normal vs. Compatible)

From here: (FAQ's)

http://vipersaudio.com/blog/?page_id=28

3. Can I still install V4A if I already using other sound mods?

A: Yes, after installation, open V4A app and switch to Compatible Mode.

From here: (Instructions)

http://vipersaudio.com/blog/?page_id=52

7. After installation done, Reboot device.

8. If you want to use only V4A as audio effect, follow normal mode. If you want existing audio effects to work, follow compatible mode.

Normal Mode:

9. In Sound settings > Music effects, always choose V4A FX unless FX is not installed.

10. Open up V4A FX (and xhifi), in menu, FX Compatible Mode set to Normal Mode.

11. If not working, try Compatible mode before trying Force-Enable.

Compatible Mode:

9. Do not change anything under Sound settings/

10. Open up V4A FX (and xhifi), in menu, FX Compatible Mode set to Compatible Mode.

11. If not working, use Normal mode and disable other effects.

Good luck!!!

What you do to change and have this?
[Android Head-Units] PsychoMcSatan:
So sure enough, this tiny system image(?) does seem to reset permissions on the file system in likely a more complete way than a regular "Factory Reset" from within the menu system. Since a few updates ago, my ES Explorer could not see the contents of certain system directories (and yes, I did configure it properly). After installing the linked System Image file above, all my apps were cleared and everything set to default like a Factory Reset, but once I re-rooted, I could see all directory contents.

It does take a little while so I thought my unit had hung, but it does eventually boot up. So anyone having file system access issues, this looks to be a working fix.

And don't be confused by the instructions above or the video. It installs like a normal System Image so just unzip to the root of your externalSD and then run a system update as if you're applying a new system image. It'll eventually boot back up with the same version you had, but just clean like a factory reset. One I re-rooted and restored my Titanium backup, I was up and running again.

As for my MCU issues, this didn't seem to have an effect. Though I did apply 4.3.1-10-10-2501 (instead of the missing one I need, 4.3.1-7-10-2501) which allows bluetooth to work but the knobs are completely screwed so no matter if I switched or reversed them in the settings, they just cause volume to jump around spastically. So I just mapped two buttons beside the knob as vol+ and vol- until they decide to compile an MCU for my hardware.

[Android Head-Units] booba5185:
Try installing Poweramp as a test, just to see if Viper will actually work. Install Poweramp, start something playing, goto Settings->Audio->Tweaks and make sure Direct Volume Control is DISABLED. Then while something is still playing, enable Viper (if it is already enabled, disabled then re-enable it) and check to see if it is working. Make sure you are on the Phone Speaker tab in Viper as well.

you have to make sure nothing else is in the sd card. once the unit boots it created folders on the sd card you have to delete those and everything else but the update files.
[Android Head-Units] PsychoMcSatan:
Yes, I already mapped my steering wheel controls to control volume as well, but my wife claims she also needs volume control.

Under extra settings there's something called "Panel Keys" which lets you change the function of the various buttons on the unit. I mapped "BT" and "EQ" to volume up and down since they are just above the volume knob on my unit. I then mapped the DVD Eject button to Bluetooth.

It's not ideal, but I wanted to move from 4.2.9 to 4.3.1 version of MCU just to see if anything else is different or fixed.
