Yep, this is another OEM Nav hack. I've seen people do similar solutions, but I think this is the first that shows how to do more than just movies. Mainly, I wanted to display digital performance gauges on the Nav screen. The stock Subaru digital gauges... suck - I don't care about my throttle position or MPG when I'm at the track. But, I like a nice, clean look inside my car, so I didn't want the classic gauges stuck all over the place.
- iPod Touch (Free - it was my old one before I got an iPhone)
- iPod AV Composite cable (~$44 - can get a generic one for cheaper)
- Composite extension cable (only need video, but my cable included all 3 - Free... I have 6 of these from other electronics purchases)
- iPod USB car charger (sold by Belkin - ~$20)
- Composite to Aux cable (Free... had one laying around)
- Composite pass-thru connectors (Need 3, $2 each)
- OBD-II PLX Kiwi WiFi plug (~$150)
- TVOut2 Mirror (requires jailbreaking the iTouch and loading Cydia - Free)
- DashCommand or Rev ($29 or $39)
Not much of an explanation on how to do this, but here are the basic steps:
1 - Pull Nav system out (pop out bezel, remove 2 screws).
2 - Cut bluish-grey wire in large harness and ground to screw (this unlocks the screen with the e-brake disengaged).
3 - Run Composite exention from back of Nav down to passenger side of car (I had to use a snake - it's pretty packed back there).
4 - Hook all the cables together.
5 - Snake the iPod adapter, USB connector, and Aux connector to center storage box. (Working on a better solution than just routing cables through the top... but I'm having issues getting into the box from the bottom side).
6 - Plug the USB power adapter and Aux connectors into plugs in the storage box.
7 - Hide rest of cabling under passenger seat.
8 - Jailbreak iTouch, load Cydia, and load TVOut2 Mirror (this allows the iPod display to be seen on the iPod and on the Nav screen at the same time).
Sit back and enjoy all the iPod functionality on the Nav screen.
DISCLAIMER - You're not allowed to blame me for watching TV / Movies, etc, and getting into an accident while driving.
My OBDII adapter has yet to show up yet, so I can't give a final opinion on the full gauge functionality. However, so far I prefer the look and feel of the Rev gauges on the screen over DashCommand... the DashCommand ones are really hard to read on the screen. More to come once I get to test out the OBD connection. I'll also note that the DashCommand application is slow, and very touchy for screen flips with hard driving (if you don't have the iTouch locked down, a little slide is enough to make it transition from landscape to portrait).
