I'm trying my hardest not to lose my mind. I've done just about everything I can to get my 797c2si anywhere close to my 788ci. I've sent it and the transducer to HB. I've rewired it directly to the battery. I've purchased a TS&S bracket not once, but twice! Now, I can't even get my unit to accept old updates so I can update the unit back to 5.450.
I started my unit up, and restored defaults. I turned the unit off, and tried the last two updates on separate cards. It wouldn't take either of them. The unit still says 5.450. I figured it would go back to facotry settings after default, but it didn't. It never gave me an option to update, nor did it change colors like it has in the past when it is updating.
What else can I do? I'm at an end. I feel I've spent enough money getting 788ci where it's at now. No interference. I just wish I got any use out of 797c2si. At this point, it's an expensive GPS unit.
