Well, I know it's only been a few days, but having an issue with iOS 8 on 2 devices and UConnect. Using the software update that came out 9/15/2014, but still having the issue.
Having the issue with both iPhone 5c, and iPhone 6 Plus.
When connected via USB, songs will play, however it never actually captures the music catalog... If that makes sense. ie... I can browse songs only by clicking next/back. Shuffle is greyed out, Browse is greyed out. No access to playlists or anything. Have drove around for 45 minutes hoping it would update, but nothing happened...
I've seen some posts on a dodge dart forum that are also having the issue, but sounds like no one has a resolution for it yet.
