I have a 899 unit that I paid 1,000.00 + dollar for a few year back. I keep it in a padded waterproof case to keep it safe, nice and clean. This unit has NEVER been dropped or mistreated. That being said I ran into an issue with my 899 SI HD Unit. The screen when black on me. When there is power hooked to the unit, if I hold down the power button and the backlight to the buttons will come on but no dice with the screen. When I let go off the power button the lights turn off. So here is the catch, after multiple calls to Hummingbird they informed me that they don't make parts for my unit. That's it end of conversation and no solution to the problem was presented. They didn't offer a discount on a new unit or a trade for a new used model. They just said they don't make the parts Had I known this is what would happen the only time i call to get help with my unit, I would hot have invested in the Hummingbird brand. I would have gone a different route. So that being said, if you have any hummingbird units know that they stop making parts after so many years and you will be stuck with a very expensive unit that can not be fixed.
If anyone has an old unit they don't use anymore please let me know. Hummingbird - if your out there and reading this I would appreciate some help regarding this issue. My boat is build around the Humming bird brand and I cant afford to switch.
Please Help!!
