09 TSX w/ navi - Looking to change the clock from 24 hr time format (i.e. 1:00 PM = 13:00) to standard. There is nothing in the manual about changing the format and I can't find it messing with the settings. Can someone point me in the right direction? Thanks.

 

hit clock once? This is just a guess since its not in the settings menu. I changed mine but don't remember how Maybe hold the clock button first and hit it again to change the format

 

There is no clock button on the head unit with the tech package like there is on the non-tech cars. The nav satellites send the clock time signal to the car. It can be adjusted via menu in the settings on the nav screen. When I try to adjust it, it shows 1 o'clock and not 13:00 on the nav screen, but the clock display on the LCD readout bar on the head unit stays in 24 hr format.
