For a car that's supposed to be minimalist, I'd have been happier with a HU that didn't try so hard to look better than it is. The on-screen buttons are a joke and the NAV is pretty useless. So much stuff around the screen that you can't see cross streets ahead of you. Sure, you can zoom out by pushing THREE BUTTONS but then you can't see the small streets. My 2010 STi had a much better system and I wasn't really that pleased with it either, but it was more user-friendly.
So far I like the BT audio (never used this before), but I wish it'd pull the tag info. Do any HUs do this or is that just a limitation of BT?
I'm going to have to look into that Pioneer 8400. I really liked the 4100 I had in my WRX.
