Borrowing parts from a 2013 Civic you can now add a sliding armrest to your 2012!
Upgrade for 2007-2009 CR-V models. Swap your stock armrest with the updated versions found in 2010 and up models.
The accessory armrest for the Honda Fit provides both storage and comfort. It also can fold up when it is not needed.
Do you have a LX or manual transmission Element without an armrest? Well if you have less than 30 minutes to do a little work you can add one!
