about the radio , its not bad at all......unless you are picky! and demand full clarity from a 100$ unit.......but if your like me you will use the SD card almos 100% of the time. bluetooth also works great! i recomend to take the extra time and install the Mic that comes with it .....it made a big difference on my phone calls while in the car.

the scrolling part for music on the SD is a little tricky and you need time to adjust. once you learn how to switch from folder to folder in SD mode you can press the "back button " and the selector will drop down to the music of that folder then you can scroll by song with the **** insted of the "forward or back buttons" again unless you have tons and tons of music this may take a while . but remember that this unit does not handle "high capacity SD cards" so for now 2GB is the most I have been able to use.
hope this helps .
