I have been wanted to upgrade the head unit in my car to a full screen unit with navigation, IPOD controls, bluetooth for my phone, and Sirius (I already have a subscription).
The Pioneer F series seemed perfect. I don't care about DVD, so the F700 was fine, but spending more for the F900 or F90 was okay.
I was ready to go until I read this forum... I'm afraid you may have talked me out of the Pioneer.
It seems like the things lacking on the Pioneer are things that are important to me and would drive me nuts. Here are things I've read that would keep me from purchasing the unit.
