That's fine for some things, like graph or a trolling motor on a smaller, uncomplicated boat. You aren't going to do as nice a job as a professional would integrating Vessel View with network linked graphs and trolling motor along with the stereo, VHF radio on my 25' bay boat. I rigged the linked units in my Bullet, and it took me a day and a half, and I can tell you for sure where it could go wrong. It took a day and a half to do, and longer to remove when I sold it.
