anyone know if there is a way to code or set the RNSE to remember that its on shuffle in between it being off/on?

my 2007 would remember to stay on shuffle 75-80% of the time but the 2010 i have doesn't remember ever. it actually seems like it's remembering and purposely turning it off... when i hold down power it goes black. turn it back on and it say smix at the top for a second then turns it off.

jw if there is a way to control this, or if its just random?
