The 5 spd EX does come with a small folding armrest on the drivers seat only. You can get an optional large storage type armrest for it. However, Honda does not recommend fitting it because it could possibly interfere with operating the parking brake. I put the large armrest on 5 spd EX and have not regretted it.
Very curious. I was lead to believe that there was not an armrest on the 5-speed at all. Thanks for the update - I guess i should have read the installations guidelines on the web more carefully - it's the full-size armrest that is not suggested to be used - it does not mean that there was not an armrest in the first place.
