Hi, just got a new to us Sylvan 8522 cruise n fish. It's a 2017 and it has an older fish finder on it, but I am going to switch it out with my Garmin. It appears to have a place in the dash for a flush mount plotter/fish finder, but the plastic is very thin. My Garmin does have a flush mount kit, but I am wondering is there anything else I need.?
I'm almost inclined to use the bracket I used before just to mount it on the helm and use the swivel, though the flush mount is a nice clean look. Anyway, has anybody put on there? any mounting tips? I put picture on here for reference. It's the big empty square space in the middle
