GTN750 no contest. (I have most of the RPX guages and the 530). See pics at link below.

Is the GTN 750/650 nav database up date able? I realize this question has been asked before. Is there any way possible?Thanks

Yes, but it costs a lot. See towards the end of this avsim report.

The Garmin GNS Trainer and GTN Trainer program uses the exact same file format, so if you have one, you can use it for the other.

 

If you are willing to live with "recently expired" navdata,  it is available in the community, just like recently expired paper charts are available at flight schools for flight sim enthusiasts.. send me a PM if questions..

Well, as I bought all RealAir Dukes, I´ll get this one. Unfortunately no GTN 750 for me at the moment. Just out of my spending budget. I´ve used the GNS530 in all planes. It´s nice but so complicated. Like someone else said, still feeling utterly hopeless in using it. GTN 750 is with touch screens, right? That should make the interaction way easier than these pesky knobs.

GNS 530 is pretty easy... It won't do airways like the GTN though

 

Just google GNS 530 tutorial there's a few you tube videos out there.

As pretty much everyone else has said, go for the newer GTN units as they are the way of the future in regards to compatibility and functionality.

 

The only reason i'd recommend the 430/530 is because they are more widely used in real GA aircraft than the GTN units at the moment, and would be more of value for training purposes. (eg. I am doing IFR training IRL with twin 430 equipped aircraft).
