hello i have avic f900bt , if i playing mp3 from usb and schut down the car for 20min

its dont remember te song it playing the first mp3 from usb ,

but everything els remember it well radio , instelligen ,

but from usb not ?

thanx

ok try this, start playing a MP3 on your computer, then shut down the computer. now restart the computer, does the mp3 start playing in the middle of the song? or does it even remember that it was playing a song in the first place?

the short answer is no, that is just the way they are designed, which is the same for most brands of radio's

now when you shut off the radio while listening to a CD, the laser stops moving, and then when it is started back up, the laser is in the same position so it can start back up in the middle of a song. it is just another drawback to using flash media(SD or USB) as a source.

ok sorry

no problem, i was just trying to help you visualize why it doesnt work
