I was able to install a larger 8 port hub this past weekend and get the BBWX1 installed and Sirius Weather working. Thanks for your help with this. Now I'm thinking i will add AIS since we plan to do a lot of overnight trips. Once I get the receiver, connect it to power and antenna and the hub, what else is needed? I am running the latest software and c-map on right ghost unit and navionics on main left unit. This doesn't seem that hard. It was suggested that I upgrade my radio to a new one with a AIS receiver but I have no idea if that can be connected to VX2 and show up on screen. Any thoughts or suggestions? Am I missing anything here?
