Yes, installed them myself, there are detailed directions in other threads, but basically you get your fingers behind the edge of the existing mirror and apply pressure until the plastic retaining latches release. A bit nerve wracking the first time... ;-) ! Then disconnect the heater and dazzle wiring remove the old mirror elements and then connect up the new mirrors elements and pop them in. On North American tregs, there is only factory "anti-dazzle" wiring to the drivers side, which I didn't use, so I wrapped the connector with self vulcanizing silicone tape ( to waterproof it) and tucked it up out of the way.
It really is a simple job, and will improve your rear and side view immensely.
