That's the way mine works, and if you have the sync on and there is a selective fade with IBOC .... WHOOO boy you get the digital rushing noise that reminds you of a train running through. It's better in narrow, but PFFFT I would rather listen in wide.

From: gkinsman1 The 2010 shouldn't "automatically" be selecting the sideband in sync mode. Mine doesn't work this way.
Also, listen to the 2010 in sync mode on an IBOC station, and you'll hear digital "rushing" noise, no matter which sideband is selected. On the E1/E1XM, in DSB sync, this noise is absent.
