I have just installed my new F900 and i have a weird problem with the sound. When I start up the car for the first time, it plays the mp3's that are located on my 8gb kingston SD just fine. When I turn the ignition off and then on, the f900 tries to resume the mp3 and I get all garbled sound and I have to reset the unit. I hope here is someone who has a solution. Thanks.
