I noticed that posts regarding how to mount a cell phone or other device to the BV 350 are out of date. The newer model 350s make this very simple. I installed this model Ram Mount (RAM-B-176-A-UN7), available from Amazon for $58. All you need to do is remove the Piaggio bolt from the center wind screen support, and then install the mount using the bolt that comes with the Ram Mount. It is such a perfect fit that I think Piaggio must have designed this piece with the Ram Mount in mind.
