This is a very tough question. I think I would. But there are some annoying issues with the F series that I wish Pioneer would fix.
The navigation is very sub-par to my old Kenwood KNA-DV4100. In fact I really don't use the nav at all. I end up using my VZ Navigator instead.
I really like the SD card, but the music player is junk. Something that Pioneer could easily fix.
One thing I noticed this week was a power supply problem in the unit. When using the video input, the screen flikers with bass hits.... LAME!
