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 619UAB 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).

Detachable Faceplate

The face plate detaches and you can carry it with you for safety and security.

Bluetooth Hands-Free

There is flip side to the Bluetooth Audio Streaming mentioned above. With this function you are able to answer you phone with just one press of a button. When the call ends you can 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.
Compatible With Audio Output of iPod / iPhone, Smartphones and MP3 Players

You can connect a device that has an Auxiliary output, such as your iPhone/iPod, smartphone and MP3 players straight into the Auxiliary input of your head unit. So basically a cable that has (2) 3.5mm audio (male) plugs. Important: Please beware that this feature is not the same as the “Full iPod Control”. This feature will only allow you to control your music by clicking on the designated buttons via the face or front side of your unit.
SD Memory Card Port

After the face plate is removed, you are able to insert an SD card with all your favorite music in it.
