Hello there, I just got a 2011 Prius II and want to go crazy with the stereo. I love this car and want to make the stereo rock! I am sorry to beat a dead horse but after hours of research and searches I Still can not find clarity to which unit will provide the following: Look totally factory with matching grain Provide Garmin quality GPS Sound really clear Be able to use steering wheel controls Provide back up camera Work well with I Phone 4S and work with JBL 5 channel amp I am leaning towards the Rosen unit but have not heard good review about the GPS. I drive a lot for a living relying heavily on the GPS. Your Input is appreciated. Brian
