Hello! Please help. Mid-drive Wednesday, that's three days ago, my
Dasaita 8GB+256GB Car Radio for 2010-2019 Toyota 4Runner Upgrade, 10.25" 2K Touchscreen, with Wireless Apple CarPlay Android Auto, GPS Navigation, Built-in 4G Cellular, Android 13, Qualcomm 8 Core
dropped the connection with my phone (Apple iPhone 16 running iOs 26.0.1). I tried all the easy 'fixes' listed in other threads. Turned off and on phone and headunit. Updated phone. Unpair/re-pair. No joy!

Without this feature, your product us worthless to me. Please help me fix whatever has caused this problem.
