    Writing to the Nav Screen

    FYI, For anyone who stumbles upon this in the future, the correct messages are: 0x68, <len>, 0x3B, 0xA5, 0x63, 0x01, <index: 0x40 + Index number (1-5)>, <Text>, <CRC> Then Update the screen: 0x68, 0x06, 0x3B, 0xA5, 0x63, 0x00, 0x00, 0x93 As previously stated, you need an MKIV Nav with software version > 40. Note that you can write up to 38 characters per line in this mode. Thanks! -Ted

    Writing to the Nav Screen

    Richard, Thanks for the reply! I actually have the all the messages to write to the different fields down, as seen below. I realize that the "static" mode won't work on the unit pictured, but the unit in my car is a MKIV with the newest software revision (from 2008), so I'll test it there once I figure out what the secret sauce is. Hmm, it sounds like you're saying I may be able to write more than the 14 characters to an index field, then send another command to switch it to "static" display mode, where the extra characters will be displayed -- is that right? Another question; Am I correct in assuming that the static display mode only supports a max of 32 characters, due to the protocol only allowing 32 data bytes per packet? Thanks! -Ted

    I think I may have found it -- is it this? 68 21 3B D4 03 1A <00 - 07> <Text> <CRC> It doesn't seem to do anything on my MKIII unit with software 3-1/31, but I'll try my MKIV unit later. I see that the static now playing screen is an MKIV-only feature, so this makes sense. I was still unable to get this to work on my MKIV unit :/.

    Hello, Kind of unrelated, but does anyone know what I-Bus message is used to write the text to the Static"Now Playing" screen (center of the Nav screen). For example: Thanks! -Ted
