    I'm looking at swapping my 440 for a 540. Would plan to do this in the next few weeks and sell the 440 effectively like new as I've had it less than 2 months so still have everything it came with and the warranty is barely started.

    For people who've used both, is the switch worth it?

    No question, the switch is worth it.

    I think the upgrade to 550 would be more useful than to the 540. The 440 to 540 upgrade primarily just gives you a bigger screen. An iPad running IFD 100 gives you that.

    The 550 provides AHRS SV which unless you have some nice glass primary instruments you’ll really find value in.

    I would not spend money to go from a 440 to 540 but I would to go to the 550. Just my opinion.

    Agree that the 550 is a better choice. Having seen one in action, I'm overwhelmed at the utility that brings to the GA party.

    If I already have synthetic vision fed from an external AHRS on my tablets, does that still make the 550 an attractive option?

    I personally think so. I have a stratus 2 / foreflight as well and since adding the 550 have never given the iPad SV another look.

    Although it’s not my primary method I can easily and confidently hand fly an approach to minimums using solely the SV function of the 550.

    There are some YouTube videos out there on the 550. Give them a look.

    The 550 is great, but for the cost difference, I’m not sure it’s worth it unless there are some other promo items offered with it.
