On our 2006 jazz we had a central armrest as an extra and excellent it was too. Expensive Honda part it had a lower box, lift lid and the armrest part slid forward. On our new jazz 2013 have a drivers armrest only, it's OK ish but a tad short in my opinion. You can get a Honda central armrest over £200 , not the same as the last one but not sure it will fit if one has already a drivers armrest on the seat side
