Hey all, a little background first. I have a 997c SI at my console and a 778c at the bow. I recently bought an Interlink to network them together. After setting up I found that the 778c needed to be updated to run the same firmware version as the 997c in order to work correctly. So I bought the AS PC2 serial cable, and downloaded the latest software to perform the task.
I followed the exact instructions as they lay out in the manual, but when I pressed the Next button to initiate the Update a progress bar showed up on the HumminbirdPC window but did not move. The unit went black except for two separate vertical lines of text coming from the top of the screen to about 1/4 way down the screen that were too small to be legible. I left it for quite a while because I thought it might take a bit, but eventually had to cancel as it had obviously failed. Now when I turn the unit on, the screen comes on and the backlight sweeps across the screen and then goes dark with numerous blue vertical lines and stays like that until I unplug it. I have tried to hold the View button and start up to bootstrap mode but no luck.
Any ideas? Did I do something wrong? What should my next course of action be?
Thanks
