F.A.Q. on the above FAQ.
Q. When I click the NAV button <your Navigation program> does open but it's not embedded. It just opens as a program in front of RR.
A. If it opens but does not embed, it will be down to one of two things.
1. The window name is incorrect. (use winspector to find correct window name)
2. The program does not like resizing and won't embed.
Q. I've finally got it embedded and working, however now it's not receiving any satellite signal. (I think this is because RR is intercepting it from the com port)
A. Either use a com port splitter or don't enter a value for GPS port in RRConfig.
