I'm pretty sure the F90BT was the only head unit at the time that offered that much for around $1000. All the other units with that feature set would have cost $1500+.
The other companies have finally caught up and put together attractive $1000 head units this year. However, I'd still be happier spending $700 (I actually got mine for $500, yeah for live.com cash back!) on a F90BT and $300 on accessories (like an HD radio module, an iPod, etc).
Bottom line: Navi works, BT works, dvd works, and I definitely got more than I paid for.
Bottom line for me is NAVI sucks, BT REALLY SUCKS, I dont watch DVDs while driving, and I also got more than I paid for! (MORE PAIN that is!)
Of course Pioneer had a "better" unit on paper than others did when it was released, it was rushed and there was zero QA. Remember the 1.13 software version?! Holy crap it was bad.
