Ok i have the F90bt and have been using it with no problems for the last year and a half. Yesterday i start my car and the start up screen comes on and the the whole unit powers off! WTF!!

One thing i've tried is booting up to the windows ce and i can do that, so i'm not sure why it's powering down on a regular start up when i haven't touched or changed anything.

Any help please????

I have EXACTLY the same problem as you. I am trying to access the Win CE. Would mind letting me know how to acess the Win CE? Thank you so much!!!
