I have PilotAware setup as a wifi. I've noticed I can get SD to work either using the PaW option or GDL90. Is there a loss of functionality if choosing one or the other? 

The reason for the question is that I also have an ADL Weather unit which can transmit weather using GDL. So if i select GDL as the nav source in SD will I loose anything from the PaW capabilities?

Thank Tim, that makes more sense! I've had several thread with fairly good traffic to help PaW and SD intergrate with a more standard approach. At you request the summarised thread is here

with the original thread having way more interest
