I suggest something similar to these Hard wired units from Ebay etc. They are quite easy to fit to a flat surface, or maybe a curved surface if you mount it vertically. Those featured have upgraded PD C type and usb3 sockets but if you prefer you may be able to find one with 2 standard usb sockets
Even if the parts are available separately from Honda they are designed for a different car. Probably much more expensive , and might be made in China anyway.
