The Sony CDX-GT340 is a car stereo with AM/FM radio and a compact disc player. The unit can store up to six different radio stations, and offers sound equalisation, repeat and shuffle disc play and a digital clock. When the stereo is first installed into a car, the unit may still be set to "Demo Mode" which is commonly used in many car stereo stores. Taking the stereo off of demo mode only requires a few steps.
