[Android Head-Units] Old Grey B:
I have the Ownice C500 with the DVD player.

My observations.

Radio seems good, Ownice have incorporated the front end developed by members of this forum and it works well. I didn't get the digital radio so can't comment.

DVD/cd works well.

Reversing camera works well. For those in earlier threads wondering what the back wire does, just connect the red wire in the long loom supplied to 12v at your reversing light, at the other end connect the other end of the red wire to the back wire, 12v signal from reversing light switches to reverse screen, its not CANBUS. Dont forget to use the same 12v to power your camera.

Dash Cam works well.

Playing music and videos from USB ports good, I put VLC on the unit. native player is OK though.

GPS iGo is OK but still requires a bit of work, originally it would lose all settings on a reboot, that's easily fixed by adding the line data="/sdcard/iGO" in sys.txt in [Folders]

I am still battling with voice commands, they just don't happen. If I go to the voice command menu and change the person instead of "have a nice trip drive carefully" I get ---------------------ip dri------------------ so it seems they are being clipped by something. I haven't tried TTS yet.

I installed Oziexplorer GPS software and it works well but doesn't do turn by turn navigation, still my favourite for off the beaten track..

The 4G antennas aren't plugged in yet so I don't know if that works or not.

I have tried the unit paired to my phone and it worked as a phone.

WiFi is pretty terrible, they have brought the WiFi aerial out the back of the unit but its still stuffed in the back of the dash with a whole heap of wiring and metal screening. It would be better with an aerial you could bring outside the dash.

Bluetooth, I am still making my mind up about that, its quite variable.

OBD2 is rubbish, I am told that it will be supported in a new software release, but I still can't get a bluetooth signal from the ELM module unless my laptop is right beside it, like 2 Cms away. So I think the module, built by the same company as the TV module is just rubbish.

DVBT module, also rubbish, it comes with 2 aerials and a cord to connect it to the unit, no instructions of any sort, it also has normal RCA connectors for video and sound, why? It has a USB port, again no idea, a socket for I think an IR extension but no remote or extension. It comes complete with software that looks like it last saw the light of day in about 1980. When you get the unit all you will have is a black screen with a notice "don't watch videos while driving" no menu buttons apart from an exit X in the corner. To get past that you need to turn that notice off in Android settings. This will allow you to see the first page of the menu, again no gestures or buttons to push to accept changes and move forward so end of story. Did I tell you the software is crap.

An installation guide for the C500 unit would be a big help, as would a decent user manual. Putting up a dozen or so "you tube" videos of someone pushing and swiping heaps of blurry buttons and pages rapidly for the C200 unit doesn't count. There is an inbuilt user guide which is also very lean on information.
