What feature of the QX55 supports connectivity for mobile devices?

The feature that supports connectivity for mobile devices in the QX55 is multiple USB ports. These ports allow various mobile devices to be connected for charging or data transfer, enhancing the user experience by ensuring that smartphones, tablets, or other gadgets can easily integrate with the vehicle's systems. The presence of multiple USB ports provides flexibility for passengers and encourages the use of technology on the go, facilitating functions like playing music, using apps, or utilizing navigation features directly from the connected devices.

While Bluetooth capability is important for hands-free communication and connecting devices wirelessly, the question specifically pertains to physical connectivity options. Wireless charging pads offer a convenient charging method but do not provide the same level of accessibility for device data interaction. In-car Wi-Fi expands internet connectivity for devices but does not address the direct connection aspect. Hence, multiple USB ports stand out as the most relevant feature in the context of mobile device connectivity.
