For the mean time, just shoot GPS approaches. Open up the GPS, press the PROC button, press the enter button for "Select approach," select the ILS you want for the airport you want, then press enter, then enter again to load vectors, then press proc one last time to say activate approach then activate vectors to final. Its not the cleanest way to do it, but once you do, you can hit LNAV on the auto pilot and it will fly you right in.
