I have been reading mixed feelings about the mic that comes with the X930BT. I was wondering if there are alternate mic options that can be used with this system, or does it have to be the mic that comes with the unit.
Just bought the 930bt and couldnt believe how small the knob was, it doesnt look that small in pictures..will def. be purchasing this upgrade once I get it installed.
The class usually refers to read/write speed of the card, so yes the card can have an affect on terms of loading information depending on its speed. I would assume that a class 4 card would be good enough for reading music.
