Sent my 899 in today. Humminbird service is the best.
Sent my 1199 in on Thursday for loss of 2d and fish ID only showed orange fish 200 kHz no blue fish 83 kHz. I have the washout issue also and asked about that and was told they are working on a update for it instead of sending it back. I have a 1198 and plugged it to the 1199's ducer and was fine so know it was the head unit. The CSR said they probably wouldn't fix the washout on my unit but I put it down on my issues list that you send in with Id # and unit anyway.

Mine still sucks on 800 after sending it back in. Run it on 3 sensitivity and 20 on contrast to make anything out. Quick turn around time though 8 total days on shipping and sub par repair. As soon as bugs are worked out on the Onix this bad boy will be for sale.
