2.7.38 to 2.8.8 TT Permaroot Success

Just wanted to update that I finally upgraded the firmware on mine from 2.7.38 to 2.8.8 (TT). Thanks shadow mike. Everything went off without a hitch. Used a 16GB Sandisk microSD card. I installed Baidu root, then CWM Superuser, then uninstalled Baidu with no issue. Root is maintained after reboot. One caveat I noticed when installing Cerberus Anti-Theft is that busybox is installed on these but you have to type "busybox cp" instead of just "cp" in terminal because the shortcuts aren't "linked". Using "the hackers keyboard" also sped up terminal usage haha. I am glad to report that Cerberus is working as a system app and is completely hidden. I do note that the audio recording function does not work. ES File Explorer doesn't like root for some reason but Root Browser works perfectly. Also, after upgrading to 2.8.8 the TomTom app is working when it was not before. I hope this update also fixes Waze and all apps losing GPS signal after a half hour like it was doing on 2.7.38. I kept having to reset the agps state with GPS status & toolbox.

It might be all in my head but for some reason Music Visualizer seems to be redrawing slower during animations after upgrading (but not due to rooting). Again, it might be in my head. I do not have a video of it before I upgraded. MX player is working better than before but it could be because I upgraded MX Player as well.

I plan on uploading a bunch of videos to YouTube within the week. Thanks so much to everyone involved on hacking these devices.

It would help to understand what you"re actually asking ?

As I THINK I understand it, you've got a car that has this automatic self-parking type of features where you only control the gas/break, and the car itself does the necessary maneuvering to allow the parking itself ?

And while doing so, you don't have a rear-view/camera view on your radio ?

Or do you mean you have front and rear sensors, and you don't see the sensor status on your screen ?
[Android Head-Units] roystervi:
[MENTION=4736782]kaween[/MENTION] what do you think about my last post about hooking up side mirror cameras that power by the turn signal. A splitter will be use to add the cameras to the same input as the rear camera input.. I have tested it and it work when you click on the turn signal the side mirror will pop up on the HU just like the rear camera does...
[Android Head-Units] kaween:
Hi !

I must admit not having read the forum for a couple of days (other obligations + januari is re-certification month for me, so I had a lot of studying to do so everything has been put on hold). I've read your post, but admit I don't exactly "get it". What/how are these cam orientated ? To the front, rear, "to the outside" ? Do you try to emulate a sort of low-cost solution for full-360°-birds'-eye parking views ?

Anyway, I applaud all and EVERY attempt at experimenting and thinking-out-of-the-box.

Some pictures about the results and realisation of the idea would be nice.
[Android Head-Units] roystervi:
please close your eyes and pic it "kaween" ....rear cam sees power and it turn on lol

I order some cameras http://www.ebay.com/itm/Multifunction-HD-CCD-Front-Side-Rear-View-Mirror-Swithcer-Car-Reverse-Camera-/111203910018?hash=item19e4450182&vxp=mtr that can be mounted under the mirror and they have not reach as yet..they are coming from China. I am guessing pony express lol, I have an house security camera that I was tested it with. I have notice when the rear camera sees power it will turn.

@"comptechltd" is using this http://www.amazon.com/gp/product/B00B155G5M/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 to do what I am describing..he is using this with 3 separate switches..so if he want to see the left mirror he would flip the switch and the side mirror will pop up on the HU.. What I am doing different, is to don't use a switches and connect the side mirror cam power to the turn signal. Hope this clear up some. I'll post some pic when I am done... In short ones the rear cam sees power it will pop up on the HU screen

I was thinking about this one day, because I have after market mirror for my car to match my car bumper and side kit, but style come with a price. The mirrors are so small that I can't see well and they do not have the power input to move them..

If you are still lost its all over youtube. but I mind you I did not saw this on youtube before I tough of it, so great minds think alike lol hahahha
[Android Head-Units] comptechltd:
This video is using different equipment but it is kinda what [MENTION=5906490]roystervi[/MENTION] is doing I think. https://www.youtube.com/watch?v=1r4gAY0qcaA Except he is switching the cameras using the turn signal. Turn right and the right camera comes on etc..

I work for a fire department and I speced something similar on one of my fire trucks. When you click on the right blinker a camera on the right mirror turns on and displays the right side on a screen in the cab to eliminate 'blind spots'. Of course this is in a 10 ft tall 34 ft long 48,000 lb truck....lol.

[Android Head-Units] lipe1982:
I know it's hard to explain, but when the car intend to do the automatic parking, press a button, a message should appear on the screen, saying he was looking a park. After found the park, the display should change and have the information whether to go forward or back. Look on YouTube for "Ford Kuga active park assist". Sorry for not putting the link but I'm not allowed.
[Android Head-Units] foggydew88:
There is another way to know if your board has BC5 or BC6 BT module.

- Open BT app

- Go into Settings

- Type Topway as device name (don't worry, device name will not change)

- A message box will appear showing your BT infos.

Slán!

PS Thanks to our Russian friends.

Just a question from a n00b like me...

I just did an MCU upgrade and have the impression that my radio signal got significantly better (more channels found, better audio quality) - is this possible at all?

Thanks and regards
[Android Head-Units] foggydew88:
I say yes, radio is managed by MCU, I like to think that there were improvements and bugs correction along the time [emoji346] [emoji346] [emoji346]

[Android Head-Units] roystervi:
[MENTION=3973207]comptechltd[/MENTION] yes that is what I am doing..........but I am not using a switch. Mines is on the turn signal itself... however I will add a switch to turn on the rear camera manually and the front camera.. So in total I will have 4 camera.
[Android Head-Units] wanxu:
Guys, I do have a real problem here.

I copied a new bootanimation (I was root), set it, them restarted the unit and everything went wrong then. It was black (just the first VW logo boot, then comes the bootanimation, but nothing appears) and then the unit boots but it's black. I can touch the screen and it responds, but everything black. So the bootanimation I placed must be wrong, but I don't know what to do.

My first solution was to flash new firmware, but I'm not sure if it replaces the boot animation. Anyway, I downloaded last firmware (8.9.1 for 1024x600 devices), placed it in the root of an USB stick and connected it to the unit before booting it, but it does nothing. My unit just have 4 buttons: power, home, back, volume + and volume - and I can't locate any combination that makes it flash new firmware.

Do you have any idea what can I do? Any way to force flash new firmware when there's a usb connected?
[Android Head-Units] ryhoo2:
Try to put the firmware on an SD card and put it in the first slot (labeled "GPS" probably).
[Android Head-Units] wanxu:
I don't have SD slots, just 2 USBs.
[Android Head-Units] wanxu:
I don't know what to do. I am not able to push any combination of buttons that makes the unit flash firmware from USB. Maybe there's some file that can make the unit flash new firmware without human intervention...

Or any way to connect to the unit via adb?
[Android Head-Units] Mamay72:
Device stitches not with USB and SD card or internal memory of the device.
[Android Head-Units] wanxu:
I'm sorry, I don't understand what are you saying.
[Android Head-Units] Mamay72:
I read through a translator. If I understand correctly, you are trying to flash the radio via USB. It is not stitched through USB. Only via SD card

Remove all USB devices, leave only the SD card with the firmware.
[Android Head-Units] wanxu:
Ah ok, the problem is that my unit does not have SD, just USB. If I could access I would remove the conflictive bootanimation and replace it with one correct to try to boot.

Thanks anyway.

Edit: Can you ask in 4PDA, please?
[Android Head-Units] Mamay72:
Transfer firmware files to the root of the internal memory, remove any other USB devices and sew from the device Settings.
[Android Head-Units] wanxu:
I can't. It does not load bootanimation and the system does not boot, although I can hear and control radio over wheel.
[Android Head-Units] TheSSJ:
Sorry if this is off-topic now, I just wanted to thank kaween here regarding the cabling of the SWC! Connecting Key 1 to my SWC cable and plugging the SWC ground to the car ground did the trick! I could not be happier now with my 2DIN unit! :)

Even though I worked so long on it that my car batterie had to be powered with a booster :D
[Android Head-Units] svEmirKo:
Great work :good:

Could you please tell me how to increase the icon size in apk editor?

[Android Head-Units] wanxu:
You have to use the app Apk editor, select Nova Launcher, edit Resource (it will take one minute to load), go to XML/preferfences_lookfeel and edit iconsizedialogpreference from 130% to whatever you want.

Re Dissassembly Guide

Hello,

I know that this is an old post. Please bear with me.

I am interested in the dimensions of the heat sink that you used (L x W x H).

I have 2 units one came with a heat sink on the CPU the other has none!

On the unit with the heat sink, it is the size of the CPU but its height does not reach the outside case. The manufacturer has applied some thermal pad to " bridge the distance" between the case and the heat sink. The pad is quite thick perhaps as much as 10 mm.

My trouble is that I can not seem to find a suitable combination of heat sink and pad to work properly. :confused:

Any suggestions would be helpful.

Thanks.

GPS Issues

I have been experiencing similar issues to [MENTION=1445076]striker1211[/MENTION] where my GPS signal will sometimes be lost after about 20/30 minutes of use. It will not show up in any application and can only be fixed by resetting the agps state or rebooting the unit. I have also updated to 2.8.8 and the problem seems to persist. I think the GPS is more controlled by the MCU so my next step before returning the unit as defective is to try a newer MCU. My unit came withe MCU version 4.2.15-1-10-2101. I am having a hard time finding a newer version of the MCU I need. The closest one I can find is 4.3.9-1-10-210101. Has anyone had any experience? Do you think it will work? Anyone know what the additional 01 could stand for? [MENTION=1445076]striker1211[/MENTION] have you had any luck in resolving the issue?
[Android Head-Units] ryan-mc:
I missed the earlier posts saying that. it might take removing it and some disassembly but how about getting the internal one out putting your files on that way?does it have the pinhole style reset button?

Xtrons TD630a sd card issue

Hi,

I have an xtrons unit which I think basically is the same like the an-21 unit with a different housing.

Lately I have problems with it, navigation apps started not to run each after another. Waze quits with "sd card not accessible" error message and it seems to me some apps simply cannot write on the sd card. I've tried different sd cards but it seems to me it is not an sd card or hardware problem because I can use it in total commander (check the contents, create folders etc.). The unit is on 4.2 updated from xtrons files so kitkat's fixes for similar issue don't work either.

Anybody has a clue what can be wrong with it?
[Android Head-Units] wanxu:
It has the pinhole reset button, but it does nothing. Just restart de unit (maybe reset some settings, I can't see it), but radio stations are saved. Are you saying that there's a microSd inside the AN-21 that can be extracted?

Thanks anyway.
[Android Head-Units] ryan-mc:
the pin hole is used to get the files to load you would use the pinhole in conjunction with the power button.

hold power button push pin hole while still holding power button then release pin hole but still keep power button pressed

update is displayed while files copy.

not sure if you followed those directions.

its my understanding and this is copied from the first post "SanDisk 8GB SD1N5C2-8G (1GB system storage, 6GB internal USB storage)"

im not sure if its minisd usb or what but maybe something for you to look into
[Android Head-Units] wanxu:
Thank you, I'm gonna try it right now!
[Android Head-Units] ryan-mc:
looks like SD1N5C2-8G might be built on the board and not something that simply unplugs

Last 2 digits could be indicate the cam recorder function, my unit had original 10-E501, I replaced with 10-E50101 and into the system settings appears the choice recorder on/off.

It's only my idea, anyway a MCU firmware with 2 more ending digits works with no problem in my unit.

[Android Head-Units] striker1211:
I drove over 2 hours the other day with no loss in GPS signal. Waze messed up once because my wifi on my phone dropped but other than that I'd say it was a success. The temperature here has also decreased so that could be one variable as well. I am on MCU 4.3.7-1-10-210101 from factory. Good luck.
[Android Head-Units] djblaze852002:
Mine had also been intermittent. Some days it was fine, I would drive to and from work (30 min each way) then drive for an hour or so straight with no problems. Then randomly the next day it would say no GPS signal after 15 minutes on my way to work. I hope your issue was cleared up, although I have a feeling it is either defective hardware or an issue with MCU (MCU tends to have a more direct connection with the hardware than the actual firmware). I am going to update the MCU to something newer. I will keep you all informed.

In my case it was due to high preassure of console mood (frame in central part of interior) on touchscreen. I've also read that sometimes either condensate, or broken lines on PCB, or bad soldering, or some overheated parts, or loosely connected (not aligned) cable from touchscreen may cause same behaviour.

Purchasing a new unit!

Hi everyone,

I have been updating you with all the issues I have experienced while owning 2 of these units (first one fried, second one has a defective GPS). I purchased both off ebay and they were the "single volume knob version". After my second unit failed, I am working with ebay to get a refund for the order. I am now in the market for a new unit!

Can someone help me find where to buy a new unit with the following specifications:

- I would like one with a BC6 bluetooth module

- standard definition screen so i can use most common firmwares

- ability to change color of buttons

- I like eBay/paypal vendors if possible, since they will step in on my behalf for return/defective issues.

- Am I missing anything?? I already have a reverse camera...

I found this listing on eBay

(http://www.ebay.com/itm/Android4-4-...594?pt=LH_DefaultDomain_0&hash=item3cf16e8bea)

It is the only one that lists OBDII as an option (I hope they mean OBDII via Bluetooth). But it says it comes with 4.4.4... Is that still an AN-21U that I can root and update with the firmwares in this forum?

Any help is greatly appreciated. Thanks everyone for being so involved. We have a great community here.
[Android Head-Units] macca017:

As far as the Launcher I have ADW EX and its great but the problem is every time you restart the unit it goes back to the default launcher. Anybody know how to change the launcher permanently?
[Android Head-Units] djblaze852002:
Warning: ADW EX is very nice to use, but upon installing, it seems to screw something up that does not let

ANY

3rd party launcher set itself as default even after you uninstall ADW!!! I spent hours today trying to fix this, but the only option I found is to factory reset and start from scratch (and make sure to not install ADW!). For that reason I now use Nova Launcher Prime. You can only increase the size of the icons to 130% (compared to ADW's 150%). But it seems good enough and is able to be set as default with no issues. Also I had bad luck getting google voice commands to work with ADW but with Nova Launcher is it no problem at all. I just tap the Mic icon on the homescreen. I can command my car to navigate to a location, play music by artist or any other google voice command. Lastly Nova provides some nice gesture shortcuts that allow access to the "background apps" view that I have otherwise been unable to see. There you can swipe away apps you want to no longer be in background. This helps with quitting apps or even fast switching between apps!

I spent about 8 hours messing around with this unit today. I will be making a video of my setup and all the quirks and workarounds I have found to make the unit as useful and smooth as possible, hopefully tomorrow. I also have simplified root instructions for n00bs.

I think I have this unit pretty tricked out, I hope my findings help others achieve what they want out of this unit or inspire further development.
[Android Head-Units] donaldta:
I'm gonna shoot from the hip here but do you have multiple launchers installed? If you change the wallpaper on one it doesn't necessarily carry over to the other. If you do not choose a default then the one that is present in /system/app directory will be loaded after it boots.
[Android Head-Units] djblaze852002:
See post above... I removed all other launchers and still after having ADW installed, I was unsuccessful to get another launcher to remain as default. I kept getting prompted to choose between the 3rd party and the system default. The last option I thought of was to use titanium backup to "freeze" the default launcher hopefully forcing the system to finally use the 3rd party launcher as default. But that was going a bit too far. I chose to just restore to factory, stay away from ADW and use Nova Launcher Prime instead...
[Android Head-Units] sorin129:
It has to be another way to fix the launcher without factory restore. Nova launcher looks nice but i want icons bigger than 130% for the car

Do you lose root if you do a factory restore?
[Android Head-Units] omarko:
I did a factory restore and now apps like Sygic which came with the unit are gone :(

also, the main screen now gives 5 large icons sitting at the bottom (radio, dvd, menu, ipod, nav) which I cant change.

just ignore this and get a 3rd party launcher like Nova Launcher Prime?

thanks
[Android Head-Units] sorin129:
Than I will def. will not do a factory restore because i don't want to lose Sygic. You can prob. back up Sygic with Titanium and restore after.
[Android Head-Units] omarko:
please do ! I cant wait to see what you did so please post what apps and setups you did as well as a video if possible!

thanks!
[Android Head-Units] omarko:
ok guys, its still not working.

I spent a while reinstalling everything and then for the recommended Nova Launcher Prime. Problem is that I downloaded few new live wallpapers and the unit does not remember them after I shut it down. It always starts with the winter theme one.

why is that? How can I force a specific live wallpaper to run on each startup ? It seems just impractical selecting a live wallpaper each time I start the radio.

also, the icons are so tiny ... even when at 130% magnification, they are super tiny which I can see it will make it hard once the car is moving and hitting them. Is there a way to address this and make like large 6 icons of my default apps on my home screen?
[Android Head-Units] gpmg762:
After I factory reset, I still have the apk in /sdcard/Sygic , just re-install.
