Hello All, I have been working on this issue after IOS update on my old iPhone 7, as well as brand new 12 Pro for a few months. The issue is most definitely not hardware related as we have tested this in multiple vehicles with both devices. I am not an apple developer, but do work IT at a larger company. (User Access Management, Application Support) Symptoms include: complete de-sync of headsets during music, sound, application sound play; frozen head-units after de-sync or automatic un-pairing. Crashed Applications. The issues persist while the phone is unlocked, locked, applications playing sound open or closed. Troubleshooting has included the following on BOTH devices: Reset Application(s) Forget, re-pair Turn Bluetooth off, re-pair Network Reset Factory Reset of iPhone 7 The vehicles include: 2021 Elantra with Apple Carplay 2020 F-250 with Apple Carplay 2020 Nautilus 2019 Rav 4 (Daily) 2017 F-250 2015 Tacoma (Daily) Headsets/Paired devices include: Blackweb HPhone A003 Bose Color Soundlink Bose SLIII Bose QC 35II Gaming Headset TaoTronics TT-BH053 TaoTronics TT-BH07 TaoTronics TT-BH085 Stealth 700 (PS4) TAOTRONICS Soundliberty 79 TAOTRONICS SoundSurge 77 Pathfinder 3 Uconnect MIL-PRV21 (Lund Boat) Summary for our testing has concluded that the iOS 14 updates have (once again) broken functionality with our hardware. The frustration with Apple updates has continued for years with our devices. Unfortunately, we can not safely use our phones and drive, even with the connection functionalities of brand new/older phones. Reversion to a previous iOS version temporarily fixed the issue. Unfortunately, we will need to upgrade the phones to a newer version of iOS at some point. Because of this, we have liquidated our Apple Products and purchased Android-based phones. Good Luck Everyone, Ryan
