I am the frustrated owner of an F90BT. When the unit is working properly (but rarely), I love the system. However, I am my second unit (first had to be sent to Pioneer 4 times until they replaced it with a refurbished one) and now it just enters in a constant reboot. I've looked at other companies but Pioneer seems to have the best system if they can make a stable one. So, I am hoping that the issue I am having with this unit are because it is a first generation and that the newer units are more stable, more responsive, and process quicker (i.e. loading a 2GB SD). Could you please let me know
