[Standard Packaging]
On the front of the BV9558 is an input labeled "AUX," which allows the input of audio signals from MP3 players, smartphones, and portable music players using a cable with two 3.5mm male plugs.
Important: Please note that this feature is not the same as the "Full iPod Control." This feature will only allow you to control your music and video by clicking on the designated buttons via the face or front side of your unit.
Be even safer with the interface capability that allows you to connect the existing steering wheel controls that you already have straight to the BV9558 in a wide variety of vehicles to almost any brand of aftermarket stereos. Control the volume, change channels, answer calls, and more.
The front face plate detaches and you can carry it with you in the included hard-cover carrying case.
If you happen to take the BV9558 outside of the U.S., you are able to pick up European frequencies so that you can enjoy your music abroad as well.
The Radio Data System allows FM broadcasters to send more than an analog audio signal out over the airwaves. Using a 57 kHz "subcarrier," stations can transmit digital RDS data ? 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.
The BV9558 offers four channels that can be used to hook up four speakers. Typically though, it is a much better practice to have an amplifier running your system.
