Yes,Nobeltec and Furuno both...
There are quite a few integrated systems available now.
My buddy has Furuno radar, chartplotter and sounder integrated, and his radio is also connected for GPS location with emergency transmissions. I think he can see all this on either his radar or sounder screens. The screens are about 6" each and are die by side. Everything is overlayed in his system. It all fits in the overhead bin. What else is practical other than sounder,radar,charting?
I do get what you mean by one big screen for everything, that would be sweet, but in a CC or cuddy it seems it would be in the way and could get smacked.
Of course this is just my inquiring and opinion, I do mean you are wrong or anything. Its just my thirst for knowledge !!!!!
I only last year bought a chartplotter and I am totally blown away by what it can do and the features packed into that little machine.
I would like to know how you system works when we can finally get out on the water again....
