Carenado PC 12 GTNXi 750/650

[Shugsta]

I think I may have misunderstood and maybe someone might confirm one way or another.  I thought that the two default units in the Carenado PC 12 were replaced with the GTNXi 750 and 650.  However when I enable the GTNXi in the ipad on the aircraft, only the 750 is installed leaving the default smaller unit in place.

Also, I have to go through the process of loading the unit each time I start the sim.  Is there any way of keeping they unit in nthe aircraft until I decide to remove it?

Many Thanks
