[Android Head-Units] ptolomeo:
Hello, I would like to share my experience with my first Android Head Unit (an Intel Sofia Joying JY-VM130N2), installed in my 2009 Volkswagen Passat (B6) in case it works for any one ealse.

I never installed anything like this or related to car audio, but I am familiar with computers an tablets and that sort of things.

This is the before:

The front panel gets out with your bare hands (but maybe in your case you have to use some kind of prying tool)

As an advice I read many places, don't disconnect the AIRBAG cable in the frame. I just left it hanging.

The radio gets out unscrewing 4 torx screws. You can see there is behind a blue box, and that was a Parrot hand-free that was broken and I had to also remove.

I just disconnected it, connected the Joying unit and voilà (didn't even take pictures of the unplugging/plugging process):

I just installed it with the canbus and disconnecting this cables (which I think other people connects and after they report problems with the unit...):

I had some weird problems with the bluetooth, but it seems to be working perfect now. I can send/receive calls using the Head Unit, and also I have it conected to a cheapo ELM327 bluetooth dongle bought in amazon, and working great with Torque.

Good things about this Joying product:

Cheap, it gave me the opportunity to have a GPS navi system, bluetooth hands free, and other insteresting features a very reasonable price

Installation was really plug&play, as advertised. It took me less than one hour to make the swap (I didn't install any rear cam, or microphone yet, but the unit works decently with the built in microphone).

Cons:

I suspect this unit will not last as an OEM unit, but didn't cost the same neither, I asume that

Not top notch quality here. Some buttons get deleted, the LED color for the buttons is incomplete, and the white LED color is... pinkish. Cheapo, but it works right now...

I had to solve over-heating problems. I installed a heat sink, and a fan, and a modded cover to allow evacuate the heat from the unit.

In any case I would rate this as a 6/10, basically substracting points for some issues as quality endings, terrible English manuals (at least Joying has a very nice collaborative community that makes Joying worth double it deserves). The English manual is simply sad. I had to search in XDA and their carjoying forums/blogs to find out answers I needed to proceed to the installation of the unit.

I demanded a new button that came like scratched or something, or wrongly painted; I hope to see how their after-sales respond.

If you have any questions, don't hesitate to ask. I have some questions I would search the answer and come back here...

Does any body know if I hve my Head Unit paired with my telephone, can the HU use my phone's data plan to navigate or do online stuff?

Can I start SYGIC in the background everytime the Head Units turns on? I live in a place with many speed radars and the main reason I want this unit is to advice me of speed radars in case I get distracted... Now I have to manually start Sygic every time...

How can I improve the radio reception? AM doesn't work at all...

EDIT: I forgot to mention I found it extremely easy to install (AND REMOVE) this units... I think, I could steal this unit in 2 minutes. 3 minutes if I remove the cables carefully and also steal the GPS antenna... Have to do something about it...

EDIT 2: By the way, if you're interested in buying one Joying they have a promotion code 'joyingESP' with a 10% in the Intel unit. I don't know until when that code will work. If you need it, just try to use it and good luck.
