First off great site. Now my problem, just had my f-90bt installed about three weeks ago and find that it won't boot up every time. After splash screen comes up and goes away music will start to play but I can not do anything else. Buttons on screen will not do anything, acts like it is froze up. I almost think that my blue tooth is causing this problem so I have turned this fuction of my phone off so it will not auto connect.

When it does this I have to turn off my motor and restart it and usually head unit will then say "wait system starting" and then everything works like it's supposed to. Thinking about adding an on/off switch that I can use to manually restart the system with out having to actually turn my truck on and off.

Any ideas?

I have that issue as well. I think it's happened to me twice. I've seen that both times, I was using the Bluetooth feature, then turned the car on before the call fully ended (i.e. waiting in a gas station and using Bluetooth).
