I am having a smiliar problem...kinda. When I come out to the car in the morning..or sometimes only an hour or 2 after the car has been off....the computer is booting from scratch. I gueess it is just loosing power while the car is off for some reason. I too amusing the P1900...and had no problems until a few weeks ago. Also...for some reason all of the sudden I am not getting the turn on "bong" noise...then again i dont remember if i ever was with the usb sound card. If anyone has any input it would be great!!
