I used the oeaaa.faa.gov link and it took me to the exact place I needed. I forwarded the letter I had sent to Garmin and I am expecting to hear back from one or both of them soon. Thanks for the info.
As far as using the obstruction info on the GMX 200, I find it extremely useful. I have had very few if any reliability issues with its accuracy. No pilot but an extremely foolish one would rely solely on the presentation and it certainly does not lull me into any sense of security while using it. In fact the entire point of the system is to alert you to a possible safety issue. In other words to heighten your concern, not put you at ease. It is a tool, along with TCAS etc to assist pilots in becoming aware of possible safety issues. I would rather have a warning of a tower that no longer exists than no warning of one that does exist. If I am landing near a tower presented on the system, of course I put eyes on the actual tower (s). Sometimes there are multiple towers in the same area, some too short to be in the data base. I have noticed that tower builders like to group their creations together, tall and short.
If there are towers in your area that need updating, even if you are unsure of the height of the tower, take a proactive approach and let the right people know. It will help you and may save someone elses life in the future. Or you could wait for the gubment to take care of it all for you
I know they are supposed to take care of it and tower builders and wire stringers are supposed to report their stuff, but we are all human and things can happen.
Here are the two I am reporting for scrutiny:
First location is: N35.23.55 W110.52.90. There are a couple of low comm towers together. This location is 205 degrees, 2.7 miles from Tolani Lake, AZ
Second location is: N 34.38.180 W 111.06.546. This is a tall comm tower just north of the Blue Ridge Fire Department, AZ. If you find the helipad, look .1 mile north and you will see the tower on google earth.
