I installed the Vais MML-L1 for my 2005 IS300 and i can play everything fine off the usb stick but when trying to fastfoward or rewind, its painfully slow. I can't fastfoward to the exact spot i want to, like i can with the stock cd player where it responds instantly when rewind/fastfoward buttons are pressed. Changing tracks is not too bad but i wasn't expecting the slow rewind and fastfoward. Do other owners of MML get the same lag also when playing files of the usb stick? It happens with all the files, mp3, flac, wav.
