The USB port of the Buick Regal is located inside the small compartment between the driver and front passenger seats. Main functions of the USB port: Utilizing the vehicle's standard power supply, the USB port serves as an interface for charging electronic devices or as a fixed power source for electrical appliances. The USB interface is a type of automotive transmission cable that offers advantages such as fast data transfer, user-friendly operation, hot-swappable capability, flexible connectivity, and independent power supply. It typically serves as a universal interface for USB devices like flash drives and MP3 players. USB port applications include: Playing music from a USB flash drive, charging mobile phones and MP3 players, functioning as a USB car cigarette lighter adapter, serving as an interface for radar detectors and dash cams, and charging laptops and tablets.

I've been driving the Regal for three years, and the USB port location does take some getting used to. It's hidden in the upper left corner of the storage compartment under the center console, right in that phone tray in front of the gear shift. Took me quite a while to find it the first time - the placement is somewhat concealed. When inserting a USB drive, make sure to clean out any dust as accumulated debris can cause poor contact. By the way, it's better to plug charging cables into the separate Type-C port nearby - mixing ports can cause device recognition issues. Remember to use high-quality USB drives; I've experienced situations where cheap drives kept triggering pop-up warnings from the car's system.

The USB port layout of the Regal varies by model year. For the 2017-2020 models, it's located inside the storage compartment under the center console, while the 2021 redesign moved it to the armrest box. To locate it, first open the flip-top storage compartment beneath the center console - the port with a musical note symbol on the front left side is the one. Check for a phone icon next to the port, which indicates it's dedicated for charging. The interface supports storage devices up to 128GB, but only reads FAT32 format. Last time my friend bought a 256GB flash drive that wouldn't read at all, but switching to a smaller capacity solved the issue.

It's located at the upper left corner of the storage tray at the bottom of the center console, right where your knee touches. Open the phone storage compartment, and you'll see the square-shaped port at the front left corner. Don't insert the USB drive too forcefully as the plastic frame can get scratched easily. I recommend using a short USB drive - I've seen people break the port when their extended USB drive snapped during sudden braking. Also, wait about half a minute after starting the vehicle for the system to recognize it; don't rush to unplug. For music playback, MP3 format is recommended as FLAC files may sometimes lag.

The USB port of the Regal is hidden in the storage compartment beside the driver's right leg. Look down at the rectangular storage box in front of the gear shift lever, and you'll find the black port with the USB symbol on the left side inside. Note that hybrid models after 2020 have an additional port in the center armrest. When using it, choose a USB 2.0 flash drive, as USB 3.0 may sometimes have unstable power supply. Plugging in a flash drive during a car system upgrade can easily cause errors, so don't let the 4S dealership update the system with a flash drive inserted. My car's system crashed because of this.
