There is the usual lack of documentation from Carenado, but they have utilized a menu system allowing several states of aircraft readiness, the last being fully powered up systems and engines ready to fly. I too like this aircraft and purchased the Carenado version from Day one of release, the visuals inside and out are extraordinary and will not leave you disappointed. Also want to know if it uses the default GPS from Microsoft. I've always loved this commuter since I've flown on it several times. If you have it, I would appreciate hearing your opinion about the plane. Looking for some forum members opinions on the new Carenado Saab 340.
