Thanks @Awful_Charlie. I went ahead and bought the AEROX 4110-712 SERIES OXYGEN MASK FAA-TSO as we already had cannulas. My problem with the cannulas was I was needing more oxygen at 17,000 as my pulse-ox was dropping into the mid 80s so ended up descending to avoid issues. With the Aerox Flowmeter showing excellent flow we went back up to altitude on a much shorter trip over the weekend and the pulse-ox showed 95% and above consistently with the flowmeter at 18K. I misread the specifications as it says it delivers a minimum of 2.5 lpm. I am new to high altitude flying and appreciate all of the information I have gotten from those who have done it a lot.

Thanks everyone. The reason I asked was the masks we purchased for flights into the flight levels requires a 2 lpm flow.

Yeah, I ended up buying the FliteChart and SafeTaxi (first one in the link) and all is well now. Thanks all!

Anyone know what the expected flow rate in liters per minute the built-in oxygen system of a 2000 Mooney M20M Bravo should be? Also, what would one need to measure the output and validate that it is putting out at least 2 liters per minute?

If you have this card and would be willing to copy the contents onto a blank 2GB card or send me the original card if you don't need it anymore, I'd be grateful - let me know how much. Garmin doesn't sell it anymore and my unit is missing it.

Thanks kortopates. Interesting because I took a blank SanDisk 2 GB card and was able to just copy the files off of the old 512 MB card and put it on the 2 GB card and it boots up and does all the stuff the 512 MB original did. But, when I added the SafeTaxi and FliteCharts to the card (and it did put the data on the card) it didn't see them in the GMX-200. Leads me to believe that you need the image of the part 010-10820-01 data card to initiate the features.

Garmin didn't give me anything other than subscriptions to SafeTaix and FliteCharts. So subscription done. The card I have that came in the unit is a 512MB SD Card. The card needed for the activation of SafeTaxi and FliteCharts is 2GB. Garmin confirmed that part number even though they don't sell it anymore. I just need someone who has that card to image it and send me a copy of the image and then I can download my subscriptions to that. How frustrating...

Garmin doesn't sell the card anymore. They say Jeppesen sells it. Jeppesen says they don't sell the card either. So I'm trying to find someone with the card to make a copy of the contents and I'll provide a drop box for them to upload the data. Otherwise, I'm stuck.

Thanks McMooney but the GMX-200 doesn't use CompactFlash but Memory Cards. Different connections on the cards. :-)

New owner of N2231X a M20M Bravo and loving it! We have a Garmin data card in our GMX-200 that is only 500 MB. Garmin gave us free SafeTaxi and FliteCharts for the GMX-200 at Sun N Fun and the files are almost 1 GB rendering the existing "chip" invalid. We purchased a new 2GB SD card and downloaded the charts from flyGarmin to it (or so it said) and inserted the card but it was a blank screen. I have taken the old card and loaded it onto the new card and going to insert that into the unit tonight. My quesiton is, does anyone know how to prep a new SD card for use inside the GMX-200? Also, what's the largest card it will support if you know?
