As yet, it lacks SPDIF output but we could put it to test to compare analog vs optical ! For short interconnect I'm hoping there won't be any perceptible difference in SQ.
      Lets meet on Sunday and finish it off. Please ping me ur number once again. My phonebook is going bonkers atm

      Congrats on the project. Whats the progress on this project? You were saying about tab integrations. Can you be specific?

      About using kodi skins in the raspberry pi3, did you make a skin for it?

      Project is still in progress, currently a portable version has been developed that can be plugged in to the USB car charger.
      It will have integrated digital MIC for handsfree calling and an audio DAC. Hoping to release next month.
      Full version has additional functionalities but requires more cabling.

      We haven't delved into tab integration in vehicle dash, so will have to be used with aftermarket tab holders.
      Project has been specifically developed for using android tablet or phone and not with raspberry touchscreen.
      Probably we can add support for KODI app on android by auto mount of a USB hard drive on Raspberry as NFS music server.
      It seems Kodi has added MPDclient support too and the unit has MPD support for apps like bubbleupnp.

      The aftermarket tab integration is just for Display purposes I suppose ? Still audio will be decoded and routed from your solution right ? And does your solution support Tinkerboard ? I remember you saying you want to take Digital out (which was not implemented yet). Tinkberboard natively have Digital out and will ease a lot of tasks for you I guess.

      very well, looks good. Anything on the obd side? for displaying the climatic info as such. Another way to get info is over bluetooth serial port from infotainment.

      Yes, audio is decoded through the device. Bluetooth audio will be of much higher quality than most bluetooth devices in the market because the system uses CPU cores and floating-point resampler which is a lot faster.

      SBC is the codec used with the A2DP bluetooth profile and it is the codec that linux supports. Although there are proprietary codecs like AptX in the market,in subjective tests, we haven't noticed improvement in the audio quality, and there’s also some research suggesting that aptX isn’t really better than SBC when SBC is used with similar bitrates as aptX.

      For more info:

      Another benefit of this solution is that you can effectively use Android-Auto standalone app by making use of BT HFP/A2DP and remote control for navigation & voice command input.
      Tab or phone can be used as MPD control point for WIFI/lossless music streaming.

      OBD Integration can be done with aftermarket OBD bluetooth adapters and Torque Pro app.
      TPMS apps can also be useful with aftermarket TPMS sensors.

      Will add a variant with SPDIF digital out very soon.

      AJ_V can this be installed separately meaning I have a RasPi and Allo DAC. Can it be installed over it? Let me know as I can help you in some testing if needed.

      Here is a demo of how I've used Tasker app to automate tasks like the auto detection of USB power when ignition is turned on and then launching favourite apps. Once tasker detects the USB power, I've added tasks to launch ICEapp, set a few seconds delay and then set another task to launch Android Auto app. It also sets the display timeout to 20 minutes. While ignition is turned off, tasker sets minimum value supported by the tab which is 7 seconds, so it turns off the display after 7 seconds. I guess adjusting screen brightness can be done too if the tab has a light sensor.

      I've installed Samsung tab A 2017 in my Polo by inserting the front part of flip cover between music system and dash panel. This allows the tab to be taken out anytime from the back cover and can also easily access the buttons of the tab.

      Software only works with our hardware, so cannot be installed on Allo but if you have Raspberry Pi3, it can be used. If you are located in Chennai, I'll be visiting soon, probably I can help work out some solution.
