Wow! Humminbird has just sent me a email saying they have fixed my Humminbird 899ci hd si unit and it is on it's way back to me. They received it on the 17 and it is on it's way back to me on the 21 that's just 4 days turn around, Wow! Humminbird is a #1 company in my book you just can't beat that type of good service. Can't wait to get it back out on the water and see those great side imaging pictures again. Thanks everyone here that has helped me with this problem and a special thanks to Humminbird you and your customer and repair service are #1.
