How are you entering it? You should go to "Where to?", "Address", then "Spell State/Province". Enter "On" and the unit should pull up "Ontario". Press this, then press "Spell City/Postal Code". Type "Ot" and the unit should pull up several cities, including "Ottawa, ON" Press this, then enter the rest of the address. Let me know if this helps.
