Dear all, eventually one of BRaVer‘s member got copy of Honda BR-V Prestige head unit updated firmware. One I know that this firmware will allow head unit to display movie while parking brake is lowered (or you can follow my alternate DIY here). Oh ya, the head unit is Panasonic with Nanoe, don’t know exaclty the P/N.
Before flashing the firmware, please do read your head unit manual carefully! For no hazzles, just go to nearest Honda service and ask for free firmware upgrade.
Warning: do with your own risk! Download the firmware here.
Note: Don’t ask me how to do it because my Panasonic head unit is replaced already.
