Yeah, the dash is one of the biggest drawbacks to these boats. I have had multiple setups, beginning with color machine and loran mounted on the port dash to built in to dash combo units.
Now have a combo unit mounted on brackets on dash, seems to work best for me.
I always wanted to remove the helm / glovebox pod and cut the angled part off. Then put a flat panel on top and have a lot more real estate to work with. Never could get up the nerve
this is what i have now
