...in my 2010 Toyota HiLux.
Manual is less than helpful and cannot find instruction on www. :'( :'( :'( :'(
Any Hilux owners know how to do that.....?
Ok..figured it out....combining 3 different answers for other model Toyota's..
1. With ignition ON and radio OFF, press and hold the AM button.
2. After 3 seconds, it will beep. Continue to hold down.
3. Use 1 button to advance hours.
4. Use 2 button to advance minutes...........
5. Release all buttons.....Daylight Saving is in...... ;D
