    I just purchased a 2025 Prius PHEV Premium with the advanced tech package including the digital rearview mirror and I would like to hardwire my Uniden radar detector with a RJ11 plug. Are there any wiring diagrams available? I would like to use a mirror tap like I have in all my vehicles for the last 15 years. However if that's not possible, is there a tutorial on how to wire it to the fuse box and get through the firewall?

    There is a power source inside the upper moulding covering the mirror mount.
    I don't know any details; I paid someone to connect it.

    Thinking about it, I'm not sure they didn't run a wire from the fuse box, under the window moulding.

    I connected mine to a usb hub that connects to the power mirror cable thru an adapter. Tucked the hub above the mirror housing.
