A few days ago I was using my SDS100 in the car. I parked, placed it in the cupholder and stepped away. Well, I didn’t realize that there was a cup of water in the cupholder. Almost two hours later I returned to the car and realized the horror. The water had completely covered the speaker area and reached the keypad. It did not reach the SD card. I tried turning the unit on but it would not stay on. I got home, partially dismantled it to drain as much water as I could and let it dry for 24 hours. I put it back together and it’s working as if nothing had happened. No damage to the speaker, screen or any keypad functions. Kudos Uniden. Very impressed.
