For example I have coding normally 040004000400001300. To hide compass i change to 040004000400005300, because Byte 7 normally I had 00010011 (in hex 13) to hide commpas 01010011 (in hex 53). Don't use long coding helper , because bit 6 is indescribable. Type coding manually in main menu.
Audio, Navi, Phone on MFD working well. We lose only small compass.
