New problem. I was driving my 24 LX600 (with 60K miles) on the interstate yesterday and the clock lost an hour. Later last night, I turned off the daylight savings time and it displayed the correct time. Again today, I was driving on the interstate (back and forth to Wichita for a b-ball tournament) and at the same place, the clock lost an hour. Obviously, Wichita, KS is north of OKC so I didn't cross any time zones.
I also discovered that my nav doesn't work. It keeps on showing "re-calculating". I tried it several different times, including after turning the car off and restarting.
Any suggestions would be appreciated. I have no idea what is going on.
