The SD card slot is for the navigation system. For vehicles with the naviga-
tion system, the SD card (Toyota genuine) with stored map data is inserted
into the SD card slot and used.
● This mode may not be usable depending on the portable audio device to be
connected.
● Before using the auxiliary jack/USB port, refer to the instruction manual for
the portable audio device.
● Use a commercially-available, non-impedance (3.5 ∅) stereo mini plug for
connecting the portable audio unit to the auxiliary jack. Before using the
auxiliary jack, read the manufacturer’s instructions for connecting a portable
audio unit to the auxiliary jack.
● To prevent discharging of the battery, do not use the auxiliary input for long
periods with the engine off or idling.
● When connecting a device to the auxiliary jack or USB port, noise may
occur depending on the connected device. If the device is connected to the
vehicle’s accessory socket, the noise can be reduced by unplugging it from
the accessory socket.
