So i want to be able to use airplay in my boat for music.. Specifically pandora... So i want to connect a apple airport express in my boat... So i can wirelessly stream music to my stereo (will just connect the express to my boat radio) The problem is... Since this is on a boat i wont have internet connectivity on the airport express, but i would i my phone... So is there a way to have the phone connected to the airport express to be able to use airplay while still been able to use my 4G network to get pandora playing in my boat?
