For your TV, YES! We picked up a set of the CW mirrors that use the rubber straps to attatch over the mirrors and so far have worked OK for us. I did add a small wire "leash" that slips over the TV mirrors incase one decides to fall off while driving. I think I paid about $11 each on sale. Wouldnt hurt to add a convex mirror on the passenger side also for added visibility.
