Don't know about the BRZ's system, but for the Scion... they had to keep the costs down somehow right? (Basic stereo, basic interior materials, manual air controls, headlights, ect.) Reading from what the First 86 stated about the BeSpoke option sounds interesting...but $800 is a bit much in my mind, especially for a unit that uses your cell phone as its means of data and apps build in yet isn't even ready for Andriod whichh is the largest market share OS on cells phones right now.
Course they were also stating the VP of Scion was still signing off on particulars of that unit as of last Friday so I guess only time will tell.
