I have a Isuzu Dmax XTerrain MY22 and while it is loaded with worthwhile accessories and safety features I am wanting to add an extra module that will close side mirrors when you lock the vehicle. I watched youtube video on how to install module BUT the actual install action is not as easy i  have stalled at trying to remove drivers door arm rest I just cant get it off .  As the vehicle is basically new  I dont want to damage the arm rest. Any one had experience doing this MOD or any  ideas.  Feeling frustrated to say the least.
