Today we are checking out a portable GPS device from Asus called the Asus R300. The R300 packs in all sorts of features like an FM transmitter and an internal GPS antenna. Volume levels for the spoken directions are very good making them easy to hear over road noise and loud kids or music. The built-in FM tuner can also send the directions to your cars speaker systems and allows you to listen to music and hear audio tracks with video over the car stereo system.
