SIAP…I couldn’t find an answer using the search feature here or on BBC. I have a 2012 Eyra with factory installed HB 1198c SI in the console. Long overdue, but finally getting around to replacing it. Given the large hole in the console, what is the largest HB Mega graph that will fill that hole? Or does Sherm (or anyone else) have a mount that will cover that hole. Just doesn’t seem to be much fiberglass left around the perimeter to structurally hold a mount, but am sure others have already ventured down this path. Other option is to leave the 1198 in the console and use primarily for mapping and add a second graph on the side. Thanks for any input.
