Mazda 6 (2004) Stock Navi: NaviPi!
#1
Hello! 



I'm pleased to be able to finally present my completed project. I installed RPi 4B+OAP inside the stock Navigation unit of the first generation Mazda 6 (2004). I had to track down the unit and ship it to me because my car didn't come with it and painted it. 

I also used an AUX XCarLink module for Bluetooth audio + music so that the stock stereo can remain fully functional (including the small display). I also took extra care so no permanent modifications are made to the car; I made a custom Mazda to Mazda harness so you can remove everything. 



Features:


  • Functional OAP (no backup camera because I use an aftermarket Mirror camera)
  • Functional OBD
  • Functional wireless AA
  • Functional Google Assistant
  • Functional steering wheel controls (including answering/hanging up calls)
  • Functional stock stereo unit
  • GPS module
  • RTC module
  • Automatic screen dimming (photoresistor inside stock IR sensor window)
  • Temperature (including greek summers: 40-65C)
  • Functional stock Navi behavior (all buttons work, screen tilts and opens/closes, position "memory" works)
  • Safe power up and shutdown (RPi powers up on "ACC on" and triggers a shutdown on "ACC off", BAT power stays on for 15 seconds waiting for RPi to turn off safely then turns off).

I want to thank the OAP team because this wouldn't possible without them, and also all the forum members that helped indirectly with their posts and input. My Mazda thanks you all.

Looks great!!! i was going to put mine in a Mazda 6 2008 but hit a deer last year. Newer 2017 jeep replaced it so now i dont want to put it in until the warranty runs out.

But nice job.
Tested build hardware that works!!!

Thanks! Shame for your Mazda. Well maybe you can get it inside your jeep but make yourself a custom harness and buy second dashboard parts as needed as well so that it can be uninstalled without any permanent modifications.

Good to see such a great setup and execution. Looks like it was there from the beginning. Idea with custom harness is really clever.
Thank you very much for sharing, providing list of components, photos and description. We appreciate that.

We also encourage you to present your project on Reddit in Rpi section. We think that larger audience should be able to see that.
