Update, for those of you still running the "ancient" Garmin SP version 2.2 on your recent-vintage iPhones running iOS 9.0.2:
I'm currently running JB iOS 9.0.2 on my iPhone 6 Plus--Garmin SP 2.2 still works decently enough, with the following observations:
1) It would seem that you may no longer need to modify the /etc/hosts file as outlined in post #1--I installed 2.2 on a different iPhone and followed my own instructions, other than the part about editing the /etc/hosts file--everything still works, including Traffic (see below) and Public Transit routing.
2) My iPhone doesn't crash to the home screen nearly as often when I tap on nearby traffic hot spots, whereas when I was on iOS 8.x Garmin would crash to the home screen every time I tapped on a traffic hot spot.
3) I'm also finding that I no longer need to put my phone in Airplane Mode before starting up Garmin.
4) Now this is the part I have yet to understand why it's happening--for whatever reason when I try to add a (freeway) traffic camera via MyCameras it doesn't list traffic cameras that I know are nearby and used to load before I updated the iOS to 9.x...but it has no issue listing cameras that are 80+ miles away from my (current) location--e.g., no matter where I am in the Sacramento, CA metro area, it'll list only those cameras 80+ miles away (meaning, in and around the San Francisco, CA metro area). I thought maybe something went bonkers when I updated my iPhone 6 Plus to iOS 9.x so I did a completely clean install on an iPhone 4 I had lying around (I first did a DFU restore to iOS 7.1.2 since that is the highest version supported on iPhone 4, just to make sure the phone is wiped completely clean), then JB it, then installed Garmin SP 2.2 and did my tweaks--even on this phone with everything installed from scratch it shows only traffic cameras 80+ miles away...hopefully it's just something weird on Garmin's end. Actually I'll be heading to SF tomorrow so I suppose I can test to see what traffic cameras are listed when I try to view/add any while I'm physically over there.
