Hello, I have a 2005 SN 196 with Perfect Pass version 6.4. This is long overdue as we've had it a few years, and Perfect Pass has never really "worked". It's not a necessity as it never sees a course but would be nice for free skiing. What happens is, the display will turn on and off while the boat is running. And when it is on, IT BEEPS A LOT!! Also, it'll start timing. Kinda hard to explain what it's all doing, but something is definitely not right. Does anyone know if this is a common problem or if the display is shot? Might be some loose connection? Only 670 hours on the boat, so I don't think that should be an issue. Thanks. Any help greatly appreciated.
