i'll find out at 1am in the morning i'll repost and see if i got it..this what i did

i have an 04 tl with an 04 screen an 07-07 dvd rom..a few others had issues with clock sync with navigation..here a few steps that i did last night and it worked

after 1am im clock dispay about 4 hours ahead on my dash but my navi shows the correct time so i played around and went too

clock adjustment

click auto daylight off

auto timezone off

cycle towards the corect time again(like if your navi say 2am you click the + untill it shows 2am again on your navi screen

then press auto daylight on/auto time zone on

press done

do not press reset again..once your press reset the clock gets screwy again..

before from 1 am till 10pm it showed the wrong time on the dash..i just checked right now and it displaying the right time after 10am still...at 1am i'll let you guys know if it still the correct time

 

I'll try it, but I don't think it will work.
I think the clock will go back to the incorrect time when you turn off and restart the car.

I'll let you know.
