GPS data not available to apps after iOS 8.3 update

Apple admits to bug in GPS on iOS 8.3. Scroll down to "notes and known issues" under MFI GPS

Downloaded 8.3 on my iPad yesterday and today my Dual XPS 150 worked fine with WingX Pro. Check out WingX Pro for more information.

Does your iPad have WiFi + Cell? If it does, the GPS data could be coming from the iPad's built in GPS receiver rather than the external BT GPS source.

Can you tell in Wingx Pro whether the GPS is coming from the DUAL or from your iPad?

I was unable to update my Garmin GLO software because my PC refused to "see" it. But then somebody on this forum suggested that I try a very short cable. Bought one on Amazon and amazingly it worked! And having updated my GLO software, my iPad is now receiving GPS position data again even though Garmin said that a software update wouldn't help. Haven't tried it in the air yet, but it's looking much more hopeful than before.

My Ipad has both WiFi and Cell. Both are set in the OFF status. Bluetooth status ON. The data is coming from the DUAL. WingX published their fix on April 22, 2015. It Works. Check out WingX Pro for more details at Hilton Software LLC.

After posting my "8.3" problem a few days ago on this thread, my iPad 4th gen wifi iOS8.3 is now working with my Garmin GLO. Upgraded the GLO firmware to v2.7, reset and rebooted the iPad. Also, tested it with our iPad Mini 2 wifi iOS8.2.and that also worked before and after the Garmin GLO firmware update. Tested using Co-Pilot Premium, Apple, and Google maps. All is well again!

Ipads with wifi and cell have internal GPS antennas (GLONASS) these work irregardless as to wether or not cell/wifi is on or off.

Hallc, Dual data could be getting through via Bluetooth or the internal GPS supplying signal. Who knows?

You can sometimes tell because the internal GPS will fire off Cell towers quickly but not very accurate whereas the Dual may take a little time to get a fix but is very accurate. If you turn the Dual on first and give it time to get the GPS/GLONASS fix then activate the Nav App, you might get a better idea whether the data is coming from the Dual or the iPad.

In any case, you still have a flyable GPS location. 😎

I can't entirely blame Apple for this. Bad Elf and Dual, if they were actually doing their jobs, would have been verifying along the way that updates wouldn't break their products' functionality. Especially for something as important as a GPS receiver... Where was Bad Elf and Dual when the betas for 8.3 were coming out? Why did they have to rely on CUSTOMER REPORTS to realize their mainstay products were broken long after 8.3 was made public? It's truly wonderful when you get out on the water, and see Navionics failing to get a fix.

Trying to restore my iPod Touch G5 back to a 8.2. I went to the iDownloadBlog.com site and followed the instructions to the letter. I ran into a problem after downloading the iOS 8.2 IPSW file, when I did the Check for Updates, iTunes could not find the extracted file. I did notice on the web site the message, "This ISPW is not signed which means that you cannot restore it in iTunes". Does this mean I a stuck until Apple releases a fix?

Just updated the Garmin GLO with my Mac, works fine now with my iPod touch. It also connects with iPad. They had to be re-initialized first.

Afraid so. Apple stopped signing 8.2 yesterday.

You can be serious! Did Apple & Microsoft merge?

If someone downloaded the iPod Touch 5G ISPW zip file prior to yesterday, would it still work for me?

I updated my garmin glo last night to the current version, 2.70 I guess it was, used it in the car this morning on the way to work. Worked great. Tracked speed, heading, and chart rotated properly. Using iPad wi-if only, garmin pilot, with a garmin glo. I had the same issue before as everyone else it see,s with the iPad not connecting to the GPS receiver. Glad I didn't roll my iPad back to 8.2.......

You will have to use anything except IE to download the ISPW file as IE changes it to a ZIP file! However if you cant get the file anymore then its pointless anyway!!
