That's not relevant here unfortunately. WingX can communicate directly with the XGPS device (not via iOS location services), so changing that setting forces that scenario.

I found the fix below

One would assume it will work with SD if you simply alter the privacy settings.

Haven't had opportunity to try it yet.

I haven't flown for a few weeks but I wish I'd visited the forum before I flew today. I only updated my iPad yesterday and like everyone else I couldn't benefit by using SD with my Garmin glow.
My wife does have a nexus 7 so I'll have to give that a try until apple sort it out.
I did try to downgrade back to OS 8.2 but the downloaded zipped file didn't seem to work when I synced my iPad to my PC

I flew on Wednesday last (15/4/15) and didn't realise there were 8.3 issues. I have a Bad Elf Pro+ and we flew almost 2 hours with a perfect GPS lock on my iPad Mini 3 which does have an internal GPS but I tend to use the Bad Elf as it tends to be more robust and reliable.

I have just checked again now, with the internal GPS both off and on, and am getting a position fix on SD as soon as the GPS gets a navigation lock.

I always make sure I update the i-devices by connecting to my Mac and updating through iTunes as the OTA update is reputedly more likely to introduce issues as it (apparently) only updates and patches iOS whereas an iTunes hard-wired update refreshes a complete replacement OS. How true this is I don't know but there have been reported comparisons with the download images for both the OTA/WiFi update and the iTunes update and the iTunes update is a fair bit bigger.

Unfortunately this is definitely an Apple bug, and there is definitely nothing we can do about it. The GPS receiver manufacturers themselves are talking with Apple about it, though, which is a good thing.

I tried this, it works, but you have to be fast as the 8.2 build will disappear soon

FYI SkyDemon have update their FB page with some info confirming this is an iOS8.3 bug, see https://m.facebook.com/profile.php?id=113971685335895 and see also http://bad-elf.com/blogs/bad-elf/18013536-alert-compatibility-issue-with-apple-ios-8-3-and-external-gps-receivers

The article here: http://www.gottabemobile.com/2015/04/09/ios-8-3-problems-fixes/ suggests trying Settings > General > Reset > Reset All Settings to fix iOS8.3 Bluetooth issues. Sorry to report trying this has not helped.

So I also have same issue since upgrade to iOS 8.3 --- haven't been able to use SD in the air in my iPad with my DUAL XGPS150 since

I have also been experiencing the same problem since upgrading to iOS8.3 but the problem is not isolated to SkyDemon or the Satnav receiver you are using as I have both a BadElf receiver and a GNS200 receiver and the results are the same...SkyDemon Navigation does not work. More frustratingly I am being shunted around between Apple Support, SkyDemon support and BadElf support getting nowhere.
