With all the desktop trainers Garmin puts out, it hardly makes sense not to have one on your PC and make use of it to build proficiency with the system. Garmin knew there would be a massive culture shock for GA pilots using such an advanced panel. Early on, they poured money into product support and training. They made clearly written user manuals and inexpensive, quality PC trainers for this very reason. When I read about people having trouble with the system, I always wonder how many hours of desktop time they log. If you fly the desktop an hour a day for a month you will be a master of the system. The training CDs run $25, each is a working replica of an existing airframe installation. In addition, many of the PC flight sims now have G1000 panels, although in my experience they are not as useful for learning.
