So, when I picked up my '11 WRX I was happy w/ the radio system (BT, USB, Sirius) but I was jealous when I saw the 2011 Forester high end radio was a 4.5" LCD. So, I set out to find one and was lucky to score one!
USPS dropped it off today and I got to "installing" which is a light term considering I just yanked out the old one and plugged this in. LOL
I retained 100% functionality of all previous functions. In addition to the obvious 4.5" display, the radio also had HD Radio built in, and I might add works quite well.
This unit also has an input for a rearview camera (on the way...) and another port that would handle a subwoofer input.
Anyway, on to the pics! I snagged a pic of each unique screen. What's also interesting is that in one of the setting directories is the change the background and screen saver. I'll have to do a bit more research on that.
