Good luck. If you find somebody please let us all know. It is not a very "user friendly" machine. I can perform the basic functions on it (task loading, editing & downloading) but I struggle with it.

I found ownership of it was the most compelling argument against gun control I have encountered. It was repaired twice, firmware updated twice and replaced once. When it broke again, I sold it and replaced it with the LX NAV8080. Different company from LX Navigation. The 8080 is a little too small, but so much more reliable and intuitive to use.

My advice: if you ain't bought it, don't do it.

My LX7007pro IGC has worked for about 500hrs without any problems, the club has 4 of them and they have also never needed any repairs or replacements.
David what exactly do you need to know?

When I bought a near new glider (just 4 flights) the Flarm part
of the installed LX7007 IGC F was erratic. After repair by LX
the unit functioned perfectly; it never failed or crashed. I liked
it. Its moving map/Flarm display can be ignored, much better
to use a PDA/Oudie linked to the LX7007.
The software is not very intuitive but pretty easy to use so long
as you are not flying comps with AAT type tasks, that part of
the software is clunky.
There are plenty of pilots out there cursing their (expensive)
unreliable computerised varios/map displays; I quite liked the
reliability of the LX7007: not state of the art in 2016 but it
worked.

This topic may be best discussed via PM or even a telephone conversation. In a nutshell, I'm in a partnership in a 2009 DG1001 that had an LX 7007 Pro IGC installed as original equipment. I have two issues I'd like to get more information about.

The first is rather minor. The airport database still contains the original 2009 data. No update is available on the LX Navigation website. How do I update the airports information?
The second issue is more serious, and a lot more complicated. I have done a lot of work trying to solve it, to no avail. The vario speed command has never functioned properly. It has always commanded a speed that it obviously too slow. I have checked the following:
Pitot/static connections are correct
Proper TE compensation is set (electric compensation)
Proper load/aircraft weight set for the flight.
Proper glide polar set for the glider used for the flight.
Airspeed data received by the device are correct, verified by IAS display on the instrument.
Occasionally the variometer averager does not work (very rarely), and when it does not work, the variometer seems to be acting as if it is uncompensated. This is a new problem that started last season.
The aircraft has a high quality total energy probe, but it is only connected to a mechanical variometer, not the LX7007. The LX7007 is correctly connected for electronic compensation.
I have not checked the quality of the static system. My assumption was that with a new glider, it would be suitable for the LX7007.
The home gliderport for the glider is closed for runway upgrades right now, but as soon as it reopens, I'm willing to check any and all ideas, including the ones I've already tried.
I contacted LX Navigation on both of these issues. They did not respond to the first issue, and suggested I retest the IAS indication for the second. I'm certainly willing to do so, but as I have said, it's been checked.

If we discuss it here the others can also profit :)

The database for Europe normally is published on their website in spring, but there is none for 2016 yet. I don't know about the US ones, there doesn't seem to be one newer than 2009. Maybe the US distributor know something about that? Normally you can use the windows application "LXE" to import multiple different database formats, edit and re-export for the LX7007.
A friend once had a similar problem with the vario being as not compensated, in his case the vario unit had to be repaired. But before sending it to repair you should check the pressure systems and the other instruments for leaks (http://media.wix.com/ugd/043502_adf4de69363a4ba39dd91488238ca4a8.pdf). I have no experience with electronic compenstation, we always use the TE probe. Also with the LX7007 in our clubs DG1000.

I can probably help with the database update, using data from my website (http://www.soaringdata.info). I haven't done a 7007 before, but it appears from the manual that it can read .cup files for Airports/Waypoints/Tasks, and .cub files for airpsace. My site produces the first (.cup) files directly, and other airspace formats that can be converted to .cub using SeeYou desktop.
You know how to contact me privately. Let's meet at the airport sometime and see if we can get this working.

Thanks guys. Yes, LXE can export the required .lxa file that the 7007 will read for the airports database. The problem is to produce the .lxa file, you need to have an airport database to point the LXE software to.
The directory that the LXE software looks to contains files with several types of file extensions, one of those file types being .cub. So yes, 2KA, maybe a new .cub file would do the trick. I'll contact you in a while and we can discuss this. Maybe even try out that new runway.
As for the SC issue, also yes, I need to check the static system. Thanks for the link to the Winter Instruments system test. Good stuff. I also thought about connecting the LX7007 to the TE probe and configuring it for pneumatic compensation, just to see if it made a difference. I had hoped it was just a software setting issue.
I guess there is no hoping in aviation.

I had prepared this answer for you after your last post so please forgive duplication of some of the points you already know.

The last US airports data base available from LX is the Jeppesen 2009 edition. You can use the program Lxe on a PC to construct a user airports data base. The user airports file is a text file but the LX7007proIGC V2.01 manual page 89 states airport data base format is .LXA. There does not seem to be a direct way to construct an airport database in the .LXA format. To construct an up to date airport database in .LXA format using the program Lxe, you first need to construct a User Airport file in comma delimited text format and convert that text file to .LXA format during the save dialog presented by File>Export>Airports>LX7007.
There are two simple ways to construct the airports text file:
1. Create a text file from the turnpoints in the Turnpoints tab, right click>Save As>TPfilename>SaveAs type>Comma separated file (*.txt)
2. Import a Cambridge .dat file into the User Data base file (lower list) in the Airports tab. Right click>Import>Cambridge .dat file. Next, Right click>Export to save the file to disk.
You are now ready to convert the saved text file to .LXA format during the save dialog presented by File>Export>Airports>LX7007.
Before converting to .LXA format you will need to edit the text file to strip out waypoints that are not airports. It is simplest to do this exercise in Lxe or in a text editor. You can do the edit in a spreadsheet but you may find some strange characters turning up in the data.
There may be a simpler way of doing this exercise but this is the only one I know. Also useful to know is Lxe does not perform properly on operating systems after XP.

It works perfectly on my Win7 and also Win10 VMs on a Macbook. I think there can be problems if your User doesn't have Administrator privileges.

Yes that was the problem, thanks for the tip.
