Hello, i have Golf 7 (SZKAIE KR-8043) Head Unit with android 4.4.2.

This car have several canbus integrations like air conditioner, parking radar, fuel consumiption and i cant loose those functions, but i have big problem, it have internal memory (about 6GB), and for some reason spotify only intall on this unit, i tried everything to make it storage cache files on SD card (32GB), so i see tutorial explaining that need remove cache files, uninstall, then delete folder (android/data/com.spotify.music) and then reinstall spotify, problem is that after remove spotify, when i try delete folder insede internal usb flash memory, it say that i cant remove, need root for that.. And when i install spotify, it keed storage cache cash files on small internal usb.. Now problem is worse, because downloaded offline music with normal quality and if i try change to high quality, it get error and say that i not have space (i have space both on internal usb and sd card).. It disapear music when i get offline... I think only way to solve it is root and delete that folder to try install it on sd card..

I am afraid make root process and lost canbus integrations.. Somebody can help me ?

About root, i see that have Baidu root tool 2.4.6, it require android and mcu images root? It's easy to do? It is permanent or non permanet root ? in instructions tell to install superuser app, what reason ? Transform non permanent in permanent root ?

Instructions:

Download the Baidu Root v2.4.6 APK from the links above (alternate sources may not work) and the superuser app of your choice (SuperSU from the Play Store is proven to work).

Install the Baidu Root v2.4.6 APK and open.

The program is in Russian. When Baidu Root opens, there will be an agreement that you have to accept. Select the option on the Right to accept and continue. The Left option is Disagree.

There are a lot of options in this program, but only one actually roots the AN-21 U. Do not select any other option as these download and install unnecessary Chinese apps on to your unit. The root function can be activated by pressing the blue button with Russian text in the top 1/3 section of the window. The "Root" button on the bottom doesn't do anything.

The program will run some processes and may take a few moments to complete. The progress circle will disappear and the window will cease shimmering when complete.

Install the superuser app of your choice and run it. When it is gaining superuser access, Baidu Root's superuser controls will ask you for superuser permission in Russian. The option to the Right is the option that grants superuser access. The option to the Left denies it.

Once your superuser app has access to the root and is running properly, uninstall Baidu Root.

Now another problem ithatI believe that all android car dvd should have..

I have iphone 6 that i use to share Internet connection using wifi.. Problem is that ios disable Internet thetering after 60 seconds with screen off, so every time that I use car, I need manually activate hotspot on my iPhone.. Also it use a lot of battery..

So I thinked that we could have perfect solution..

Anyway I have bluetooth paired with car (ad2p), it work automatically and very well..

I would like to make some tasker script (on Android car dvd) that can detect iphone paired and then start bluetooth Internet thetering automatically, so we would have perfect solution, automatic connection using only 1 hands free connection (bluetooth only), automatic connection and low battery usage (mobile phone). what you think? Somebody already tried something like this?
