Alright so I have an 06 TSX as well as my girl. Both navi, 1 owner, navi never messed with updated etc.

We both have F CAN System Error Active showing only one code,

meter 1F4

I've searched but no definitive answer or people run the 1F4 with other codes, I only have this and both navi's seem to function properly it just irks me.
