This is probably why there is no OTA. they can not manage to get the leatest MPU work with different ECUs versions.
I want R63 becuse R59 have slow startup, and when you engage Reverse when the system has not fully lodaded it will decrese the brightness setting of the screen.
just to be sure that i understand. this is the steps to install (Trophy LR):
1. copy AVN_MPU with the usb_ota_update.zip inside to the root folder of the flash drive
2. enter enginner menu and preform AVN-SOC update
to downgrade its the same but i just need to use the R59/R46 file.
no AVN-VIP update in order to keep the newer MCU.
i correct?
