【USB/HDMI Extension Cable USB15｜Smartly Add Terminals to the Switch Hole on Toyota/Daihatsu Vehicles】

You want to connect your smartphone, USB memory, or HDMI devices to your navigation system or display audio, but the terminals are recessed and difficult to use. Or, you may leave the cables hanging out somewhere inside the glove box, making the interior look a bit cluttered.

In such cases, the Nav Option USB/HDMI Extension Cable USB15 is very convenient.

It is designed for the genuine spare switch hole (23mm × 23mm) used on Toyota and Daihatsu vehicles, allowing you to install the USB Type-A and HDMI terminals neatly in a more convenient position inside the cabin. By making use of the factory switch hole, it helps reduce the “retrofit look” and makes it easier to connect smartphones and video devices.

Convenience: plug in instantly when you need it

The USB terminals can be used—when combined with compatible navigation systems or display audio—for connecting and charging smartphones or USB memories.

With the HDMI terminal, you can also expand how you enjoy your car by enabling features such as video input and output to a rear-seat monitor via connection with compatible devices. However, what functions are actually available depends on the specifications of the navigation system or display audio, so simply adding terminals does not mean all functions will be available.

Be sure not to judge based on the product alone—check the compatibility with the navigation system or display audio you currently use.

To fit naturally into the switch hole

USB15 is a product that installs terminals by using an available switch hole.

Depending on the mounting location, surrounding interior trim, and the distance to the navigation unit, the routing of the cables and the final finish can vary. Even if the terminals are neatly placed, if the wiring on the back side is under strain, it may become difficult to handle during future inspections or when replacing the navigation unit.

At LOGON, we install not just by attaching the terminals, but by considering usability and how well the interior comes together—while also confirming the vehicle’s specifications and the connection method to the existing navigation system.

This is a part that is easy to change for those who want to “make it easier to connect a smartphone,” “enable HDMI devices,” or “make use of the genuine switch hole.”

Let’s confirm together whether it will work with your car’s navigation system or display audio, and which installation position would look and feel most natural.
