[Android Head-Units] talaman:
Okay, some impressions:

Pros:

- Device is fast. It lags a bit only during software update, as any android does

- Screen is bright. Map and navigation are clearly visible under direct sunlight right into the screen.

- Surprisingly usable pre-installed offline navigation (iGO). Interface is ugly, but in general it is ok

- 32 gig is a lot of space. SD card is needed only for music

- Sound via bluetooth is good

Cons:

- Bluetooth is limited by regular speakers/headset. I cannot connect any device to the head unit, I can only cast music and phone calls from my phone and that's all. Android just doesn't see any bluetooth adapter in the system. I can make calls using special application, sound from the phone just play when it's connected. Only one phone can be connected at the same time.

- Internal sound is very bad. I'm not an audiophile, but I've tried to play the same song from the soundcloud app from my phone via bluetooth and then from the head directly. I will probably never play music from the head unit, it is awful. Same for music from files on flash drives/sd card

- Screen frame is quite high, so I can't see some google maps interface elements (miles to next turn, top left corner)

- There's 2 mm gap between the unit and my Nissan's dash cover in the bottom. I will handle this later.

- Bad screen sensitivity in the lower part of the screen, some Ok/Cancel buttons are not responsive while installing software. Maybe, because of android lags. In the maps application touchscreen works fine everywhere.

- Android 4.4 interface is ugly to me. I'd prefer 5.

Conclusion: DO NOT BUY IT, unless you know what you are doing. Limited bluetooth looks a deal breaker to me. None of my 2 bluetooth adapters worked with the android. And without full-featured bluetooth I can't connect OBD2 and set up screen mirroring.

I'll try to send it back, but it might be too expensive and not worth it. Anyway, I keep searching for unit with good sound and full featured bluetooth (and bigger screen resolution, but I haven't seen such units so far)

I haven't attached rear camera yet. I will update this post as soon as I do.

Some pics I made (There's more of them, but I cannot attach links yet, you can add this to photos.google.com, sorry for inconvenience /share/AF1QipMkaPjBvN0gqef5SaFPDg6Br1xbnD1f1sstcIQLxlawDkqPAKsWE5ZQ3tJ1b-0F0g?key=M2NJd3FDQTFIMnBfRGF5c05RUEt3bXdKZGlMRzhn):
