Infotainment System for Porsche Car [from CAD, prototyping to finish]

Thanks Fred!

I will check out that OBDII chip you mentioned.. I really would like to a obd2 app on my phone that could work through android auto / carplay.

Years ago (10+) I used to have a software I purchased that displayed the smart phone screen on a desktop (which I could remember the name). But at the end of the day the smartphone HCI paradigm is not perfect for the car either (hence all the software experimentation) Today though I think Android and Apple have the right idea with car integration. From the design perspective you are right there is no real control (they figured out the approach for you).. In the past I was figuring out the right path. But in the end, treating it as a driver, other than some occasional quirks connecting, the experience is pretty solid, just lacking compared to what I would do in the past when I had complete control. If android auto development allows it, i think a cool path forward is adding to the ecosystem through apps. But i think possibilities might still be limited there...

Going to try to force myself to find a bit of time over the next couple of weeks with the obd2 app. Would be a really nice addition, and i did a bit of searching and there does not seem to be anything out there (other then an experimental xda-developers forum post). It might not be possible (yet).

If you decide to jump back in at any point, let me know! Would love to help in any way I can.

I will let you know, for sure. The more we are the better!

Sure you'll find a way to comm with the obd with your device(s). Never seen the unit layout or schematic but I'm sure they left you a uart interface somewhere in there for you to hack. If you go that diy route then also look up for the NXP's TJA1055 for the transceiver (low speed). Doesn't need much; 3.3-5V decoupling, CAN-H/L input and RX/TX output over that MCP2515 and that's pretty much it. Example libs and clock cpp are literally everywhere (ps. DTCs are roughly same as VW and Audi). GL!

Let me know if you are stuck (I doubt!) and I'll do my best to help out if needed.

edit: if no uart avail then just use a BT module. That (should) set-up a new com port in your unit, then just write your stuff to port over that. Easier that way maybe (less wiring lol)
