      I've started to notice that every now and then while on a cell phone call through the Explorer, I will get this hissing noise for about 2-4 seconds. It almost sounds like waves at the ocean. It starts softly, gets progressively louder and then disappears. At first I figured it was my phone or the persons phone I was talking to. However, I got a new phone a couple of weeks ago and its still occurring when talking to different people.

      I've not noticed any correlation to other events, its just random. Anyone else heard it?

      Look like no one else has heard this but me, and I can't find any other mentions of it on the net. Have the Sport in for service today and the advisor said they applied all the Sync / Radio updates so I'll report back if it the noise goes away.

      I doubt any updates would solve this issue since no one else has reported the same issue. Sounds more like some kind of short term interference. Have you ever asked if the person on the other end can hear it?

      The people on the other end of the call cannot hear it. When it does happen, its the same sound with the same characteristics. It does not sound like random interference, call quality, or signal strength.
