I´m trying to file a flight plan in the Garmin 530 in the CT210 for P3D v4 and am getting nowhere with it. Can anyone give me a hint what I am doing wrong. My navigraph is up to date. I wish there a was a place to attacht files directly here to explain. But that appears not to be an option. It would make things a lot simpler

Do you mean to file an IFR flight plan with ATC from the stock Garmin 530 ? 

I'm also struggling with this, I understand that this topic was brought up a while ago, but hopefully someone can still reply. I'm trying to enter an IFR flight plan in the Garmin 530 in the 210, but I'm getting a something completely different to any one of the tutorials I have followed on YouTube, and I have not been able to work it out. All I get is the Active flight plan page, but i cannot enter anything and there are no dashed lines for me to input VORs, Intersections, ICAO codes, etc.
