Hello, I had a weird issue on my way to work today. I was driving in the rain and turned my head lights on. When I did that, the dash lights flickered and the warning lights all came on like when you first start the car. The radio also stopped and the nav system reset to the loading screen. I experimented a few more times as I drove in, and the nav system continued to reset, but the dash lights remained on. By the time I got to work, I was able to turn on and off the lights without a Nav system reset. I did the same test at lunch today, and everything seemed to be working. Any ideas?

 

check your battery terminals and grounds for corrosion.
