Thanks for your thoughts. I'm sure you know better than I, but it is weird that it always changed automatically until I disconnected the phone. Maybe it's because we keep changing the time that daylight savings time begins and ends. I will wait, but temporarily I changed the time setting from PST to MST and picked up the hour. Now, if I could just figure out how to get the tire pressure indicators to display that would be great. My CL has every option available (parktronic, distronic, nav, AMG, you name it) and I understand that tire pressure monitors are supposed to be included (per the owner's manual), but I can't seem to get to it. Thanks again...Doc
