I just tried to install an upgrade on my 787c2i. The unit was working fine before the install. Now it will not power up. when you turn it on the loading screen appears then blinks and the screen goes black, Then it repeats that over and over. I talked to Humminbird for 30 minutes trying to figure out what happened. I now have to send the unit to them at MY COST and will have to wait 3-5 days for the repair plus the days to ship.

I was told that this upgrade would make things run SMOOTHLY and take care of some problems others were having. Now I'm out of pocket. I know this could happen to any brand out there, But when you spend this much money on something you sure don't want this to happen.

So much for fishing over the holiday weekend!
