isimple sounds awesome, but I've never done much work on cars until today I hooked up some spyder projector headlights. I've been looking for a way to hook up my Samsung S2 (Android), but I also have an old 32GB ipod touch just laying around. Adding Bluetooth would be awesome, along with HD radio, that would still keep my HUD working. I'll see if I can Google it, but I'm not sure what an ign switch relay is or how hard it would be to do that.
