USB & SD Ports View larger General Features RDS Tuner: "RDS" stands for "Radio Data System" and it allows FM broadcasters to send far more than just an analog audio signal out over the air waves. Using a 57 kHz "subcarrier," stations can transmit digital RDS data for reception by RDS-equipped FM tuners. Depending on what the broadcaster transmits and what your tuner can pick up, you can receive information such as the name of the artist/song, name of the station, genre, traffic information and more. Switchable US & Europe Tuner Frequencies: If you happen to take the BV9979B outside of the US, you are able to pick up European frequencies so that you can enjoy your music abroad as well. 7-Inch Monitor: A motorized-7 inch widescreen, touchscreen, digital TFT monitor slides out and up from inside the unit with a high quality 800 x 400 pixel resolution. Front AUX (Auxiliary) In: This little input in the front of the BV9979B that says “AUX” is an interface that allows the input of audio signals for MP3 players, headphones and portable music players. It is for audio only and not video. Output Power of 85 Watts x 4 Channels: The BV9979B offers 4 channels that can be used to hook up 4 speakers. Typically though, it is a much better practice to have an amplifier running your system.

Two Bluetooth-enabled devices (like a mobile phone and a car) can be paired so that they establish a communication link when they come within range of each other. Depending on the device, the range can be anywhere from 3 to 300 feet. The BV9979B supports A2DP (Advanced Audio Distribution Profile). A2DP is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system).
