Team Jo-Jo

Need some assistance, can you project your GPS/Fish finder screen on your TV , (Would like for our crew to be able to see it as our guest explains / interprets what is on screens )so you can see what its shows as you move through the options on GPS/Fish finder?

If above can be done how do we do it?
