No. You do not need any diagnostic tool or any software. Just an empty FAT32 formatted SD card or USB flash memory (for MIB3) and a computer.

That's all you need to update your infotainment system.

No, you cannot. Firmwares are dedicated to VIN number to keep all functions and setting same after the update. It is valid only for the purchased VIN.

If you install to another car, you may lose functions or completely brick the infotainment unit. And this is no covered by your warranty.

No, you can't. MIB is hardware. To make an upgrade from MIB1 to MIB2 or MIB2 to MIB3. You need to change your hardware.

You can perform firmware updates only for your existing hardware. For example, you cannot install MIB3 firmware on MIB2 device.
