Installed - Premium plus carenado C182 plus ORBX Tacoma Narrows and Fairways.
In free flight and doing circuits etc. without using G1000, everything is OK (so far)
Flight plan made for Tacoma to Fairways - GPS.
About 2/3 of the way down the route, I went into the procedures menu in the main flight display - OK. Cursor select button for approach - CTD!
Ideas?
