    I’m looking for help with my 2010 Toyota Prius (JBL system) and the factory E7022 head unit.

    I tried installing a Binize CarPlay radio, but I was missing some cables/adapters for the JBL setup. After attempting the install, I put the original E7022 back in, but now the head unit is completely dead.

    Current symptoms:

    • Screen stays completely black
    • No Toyota logo
    • No button lights
    • No audio
    • No backup camera
    • Climate controls still work
    • Car starts and drives normally
    What I’ve already checked:

    • RADIO fuse tested good
    • Other related fuses tested good
    • All connectors appear fully plugged in
    • Reinstalled the original unit carefully
    • Disconnected/reconnected the 12V battery
    I’m wondering:

    • Did I possibly damage the harness during the aftermarket install?
    • Is there another fuse or relay specific to the JBL system I should check?
    • Has anyone had the E7022 stay completely dead after an aftermarket radio install attempt?
    • Could the Binize setup have caused a communication issue with the JBL amp?
    Any advice or photos of the correct rear connector setup would really help. Thanks!
