welcome to Xoutpost, James...

2005, E46, MK4, 16:9 monitor, TV tuner, paid version of Navcoder.

the version of nav firmware is unknown, the nav does not really specify 16:9 or 4:3, as the full/split screen refer to a different view of information on screen.

the TV tuner on the other hand, has a setting for 4:3 and 16:9 setting...

can you snap a pic of your screen and post it?
