October 5, 2026

• New Avionics: Avidyne IFD, Entegra, and Vantage database updates via USB key • New Avionics: Collins Pro Line 21 and Fusion Chart updates via USB key • MachDB remembers the last 10 external storage devices used so you don't have to re-select them when switching SD cards / USB keys • New option to auto-select the databases previously transferred to a card/key when swapping storage devices - this is useful for systems which require different databases loaded on different cards

Doesn’t work for me

Could not find detailed instructions. Entered my Jeppesen info. Seemed to download something but it never transferred to my IPhone or data card. Jeppesen did not sense that anything got downloaded because my data was available to download via conventional system. Too bad I can’t get it to work because I love the idea.

CTCool with that

Wow. Great App

I found out about this through a Cirrus forum because the JDM manager is not supported on Mac anymore. MachDB works perfectly. I actually prefer it far better than using a computer. There’s a great YouTube video that’s made by the developer which shows how easy it is to use.

Excellent

Worked easily and quickly for our Garmin GTN-650 SD card download using my iPad mini with an SD card reader attached and cell service. Now we can dispense with using the clumsy Microsoft laptop and wifi connection method. Will help when updates are needed and the aircraft is away from home base since we can use our iPads or iPhones which we have with us anyway. Thank you for developing this.
