  1. I downloaded the 5.1 firmware from pioneer's website (currently, I have 4.6) and tried to update the unit following the instruction, the update went through and shows complete, but the unit didn't do automatic reboot, so I manually restarted the car, when in program force write, it does show the ucom version of 8.5, however, in system setting, the app version is still 4.6. Do I need special tool to be able to update to 5.1 firmware? Thanks!
