Bluetooth 3.0: The Sony MEX-GS620BT is equipped with built-in Bluetooth 3.0, allowing you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your smartphone to the head unit. In order to use Bluetooth wireless technology, your phone must also be Bluetooth compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:
- Hands-Free Communication: HFP 1.6 (Hands Free Profile), PBAB 1.0 (Phone Book Access Profile).
- Audio Streaming: A2DP 1.3 (Advanced Audio Distribution Profile), AVRCP 1.5 (Audio/Video Remote Control Profile).
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Sony MEX-GS620BT.
Multi-Device Pairing w/ Dual-Phone Connection: Up to nine Bluetooth-compatible devices can be paired to this receiver. You are even able to keep two Bluetooth-enabled phones connected at the same time, so you can make and receive calls from either phone through the head unit. Only one audio device can be connected at a time, which means only one of the two connected phones can stream audio. One an already paired device is in close proximity to the Sony receiver, the two units will automatically re-connect. The head unit offers three pairing modes - SSP, NFC, & USB Auto
- Simple Secure Pairing: With Simple Secure Pairing (SSP), you can easily pair a Bluetooth enabled phone to the Sony MEX-GS620BT without having to enter pin codes or go through complicated settings.
- Near Field Communication (for Android): Android (OS 4.0+) smartphones that have Near Field Communication (NFC) pair simply by touching the Android device's NFC tag to the head unit's NFC tag on its rotary-knob. For older Android smartphones that don't have OS 4.0 or better installed, download the NFC Easy Connect app from Google Play to use the head unit's NFC pairing function.
- USB Auto (for iPhone): You can pair your Apple iPhone (iOS 5.0+) by simply connecting it to the Sony head unit via USB and activating the Bluetooth function on your Apple device.
Hands-Free Communication w/ External Mic: The Sony MEX-GS620BT supports Bluetooth hands-free communication for your Bluetooth enabled cell-phone (such as your iPhone or Android smartphone).

- Peak Power Output: 55 watts x 4-channels (220 total watts)
Note: The power specifications for the Sony MEX-GS620BT are compliant with the CTA-2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Technology Association (CTA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.
6ch/5V Preamp Outputs + Sub Control: The Sony MEX-GS620BT is equipped with 5-volt Front, Rear, & Sub pre-amp outputs giving you the ability to connect external amplifiers to your car stereo system. The unit's subwoofer preamp output is non-fading. You can adjust the subwoofer preamp output's volume level independently from the head unit's main volume control from -10 to +10 in 1dB increments. In addition, you can select the phase of the subwoofer output from Normal or Reverse.
Note: You can also connect a subwoofer to this head unit without the need of a separate power amplifier. Simply connect a single subwoofer (4-8 ohm) directly to head unit's left or right rear speaker leads (but not both). Same subwoofer controls apply.
High-Pass & Low-Pass Crossovers: The front & rear speaker outputs offer a selectable high-pass crossover frequency of 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, or Off.

Digital Time Alignment (DTA): This unit can change the localization of sound by delaying the sound output from each speaker to suit your position, and simulate a natural sound field with the feeling of being in the center of it wherever you sit in the car. You can choose from Front Right, Front Left, Front Center, or Off. You can also set the subwoofer distance of the subwoofer to Near, Normal, or Far. You can also further fine tune the listening position from -3 to +3.
DSO & DSEE: Dynamic Stage Organizer (DS) adjusts the signal, improving the stereo positioning so music sounds like it's coming from the dashboard. Digital Sound Enhancement Engine (DSEE) improves digitally compressed music files by restoring high frequencies lost in the compression process.
ExtraBass + RBE: Activate ExtraBass at the touch of a button for an instant, low-end boost. Unlike conventional bass boosters, ExtraBass minimizes distortion at all volume levels by automatically adjusting frequency and gain to their optimal positions. RBE (Rear Bass Enhancer) enhances the bass sound by applying the low-pass filter setting to the rear speakers. This function allows the rear speakers to work as a subwoofer even if there is no subwoofer connected.
ClearAudio+: ClearAudio+ reproduces sound by optimizing the digital signal with the Sony recommended sound settings. It automatically adjusts the head unit's EQ, ExtraBass, and DSO.
Advanced Auto Volume (AAV) + Loudness: This feature adjusts the playback volume level of all playback sources to the optimum level. Loudness reinforces bass and treble for clear sound at low volume levels.

A face-fixing screw is supplied for making the face non-detachable, if desired.
High-Contrast LCD: With 5x the contrast of conventional screens, plus an optimized viewing angle, the MEX-GS620BT's LCD screen is always easy to read. You can adjust its brightness level from 1-10. You can also set its dimmer to Auto, On, or Off. The Auto mode dims the head unit's display automatically when you turn your vehicle's lights on (illumination wire must be connected).
Dynamic Color Illuminator (35,000 colors): Dynamic Color Illuminator lets you match the head unit's LCD & button illumination to complement your existing vehicle lighting components. You can select from 15 preset colors or a customized color (R-G-B). You can choose to use the same color for the LCD screen and button illumination, or use a separate color for each one. You can even set the head unit's LCD screen's illumination to pulse with your music.
Auto Scroll: The Auto Scroll feature allows long displayed items to scroll automatically across the display when the track is changed on a disc or device.
Display Illumination/Clock Display: Pressing the SRC/OFF button once will switch sources. Pressing and holding the SRC/OFF button for one second will turn off audio output, but the clock display and button illumination remain on. To turn the unit off completely, you must press and hold the SRC/OFF button for two seconds.
