I don't know.... I would assume it's the same radio and the wiring harness is missing for the AUX port. Your only option may be to open the dash and look. You can order the harness and other parts for the AUX from
http://www.hondapartsdeals.com/honda_parts.php. I've been unable to find an Aussie parts store.
On another note - maybe you can get the part from CollegeHills, see Auxillary Jack - price $54
