Bluetooth technology is a short-range radio technology that was developed to provide wireless audio and data transmission. 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 BV9757B 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).

There is flip side to the Bluetooth Audio Streaming mentioned above. With this function you’ll be able to answer you phone with just one press of a button. When the call ends you’ll be able to either hang up first by pressing just one button again or do nothing at all as long as the person you were talking to hangs up first. Just keep on driving without any distractions.

A great feature that comes in handy is the AUX input located in front of the unit. What this does is that it allows you to connect a device that has an Auxiliary output, such as your iPhone/iPod, smartphone and MP3 player straight into the Auxiliary input of your head unit. So basically a cable that has (2) 3.5mm (male) plugs. Important: Please beware that this feature is not the same as the “Full iPod Keep an eye on”. This feature will only allow you to Keep an eye on your music by clicking on the designated buttons via the face or front side of your unit.
