Hi guys,

This is my first post on here for a VERY long while. I bought a 2004 Subaru Legacy Turbo Spec B a few weeks ago. It came from Japan with an after-market navigation unit which couldn't be converted to English. So, I ripped it all out and started on a hobby project to replace it.

The requirements were:-

  • Had to replace the Japanese touchscreen. The hole was roughly 8" 16x9 aspect.
  • Handsfree phone, preferably with a way to place calls & answer calls on the touchscreen
  • Navigation
  • Music would be nice, but not essential because the headunit is a 6cd MP3 autochanger
  • DAB Digital Radio would be nice because headunit is Japanese & the radio frequencies all wrong
  • Canbus? OBD2? Nice to have



I've dabbled in car PC's in the past, so I considered doing that again with a separate cpu unit & screen. I also considered Raspberry Pi or similar. However, it was much cheaper and easier to use an Android Tab. The Google Nexus 7 fitted the bill perfectly. It was cheap (45 from ebay) and easily modified from both a hardware and software perspective, and most importantly it was exactly the right size. It was a bonus that others had used this unit for in-car entertainment so there's plenty information available on what and how.

It's turned out quite well, if I do say so myself. Let me know if you want more details of how I did this?



Next things to do:-

  • Fit a bluetooth car kit. Thinking of using the Grom with audio-over-usb input.
  • Get my bluetooth OBD2 adapter working
  • Play with CANBUS adapter
  • Get a webcam working as a reversing camera
