I'm installing this unit into my 2008 Impreza 2.5i soon and was wondering if anyone has had this unit and was able to just ground out the parking brake wire. I'm kinda electrically challenged when it comes to relays and so on, but I had heard one could just ground out that wire and it should allow for video/Bluetooth without having the parking brake engaged. I'm hoping that in the 2008, they didn't require a signal to it and I could just ground it somewhere inside the cubby hole where the head unit goes.
