Trying out some new hardware that's going into our small boat, but couldn't resist hooking it up temporarily in the big boat to see how it worked. With the meteor 300 I can stream via Bluetooth, USB, or from one of the two aux inputs. Works like a dandy and there's no head unit it's all controlled by the 741xs which makes room on the dash. Also the helm app works well with iPad and iPhone.
First pic is the 741xs itself and the other two are on an iPhone through the Helm App.
