Help with Lowrance Carbon 12

I recently downloaded the latest 2.0 update version as a repair to help me reinstall the downscan feature! It came directly from the Lowrance
website but something went wrong somewhere in the process. On the side bar display it use to read left side, right side and downscan but
not now. I seemed to have lost the SONAR feature. When i go back to the page menu, it doesn't show it there as an option. I went back to facrory
setting but it did not recover it either. The console unit is working fine and it has all the features available if i need to drag and drop a new view, no problem!
I can upload some photos from my cell phone if that will explain it better. Thanks for any and all advice than you may have.!

Sent you a private message. Be glad to give you some phone support when you can get in front of your unit. Don't have to be on the lake, on the trailer will work in figuring out what needs to be turned back on.
