I’m having the same problem. The unit recognizes the iPhone through Bluetooth (it shows the correct song playing etc) but no music plays. The FM stations play without problems. Perhaps the gain needs to be increased per the manual?
I’m planning to buy a Searay 34 ft about a 2011. There are two different engines available, the large 8.1 and the slightly smaller 377. I’m not looking for a speedboat, just cruising but would like to plane easily without killing the engines. Any help would really be appreciated.
