Greetings. I suppose these 2 issues will be for Greg and here goes: I have the 798ci si HD, which I purchased 3 years ago and which I used a few times before parking my Trident Ultra 4.7 kayak for quite a while as I had complicated personal business going on.
Now, 2 years later, I am ready to get the kayak back out and do some fishing. The problem is that when I power up the unit (and yes, I have a new, fully charged battery), the screen is exceedingly dim, if I can see anything at all. But the unit is going through the power cycle as I hear the audio working fine, even though I can't see anything. Also, when I tap the unit (actually a firm slap of the open palm) on the side, I see a flash of full color display, which immediately then disappears back to near dark if not all dark, until I slap it again, and it appears again for an instant, then disappears and so on. So I need some help with that issue, please.
Second issue, I went to the Humminbird website to do an update and I see where my unit is discontinued. Oh well. The issue arose when I was in line to update the 798 software, and I received a list of what the update will correct, followed by a warning NOT to update the software if I have the Humminbird Weather Unit--which I do. So now what? I need an update, which I can't obtain without losing the capability of the Weather Unit, which I use and paid good money for?
I am obviously stuck for the time being with no visible screen, and with a conflict of whether to update software or save my Weather Unit, and wouild therefore appreciate any advice that is offered.
Thanks in advance.
Scott
