Many iPhone users in the U.S. and Canada face issues connecting their iPhones to car Bluetooth systems. This can affect calls, music playback, and navigation audio. This AvNexo guide provides step-by-step solutions to fix iPhone Bluetooth connectivity problems with vehicles.
Software glitches on iPhone or car system.
Outdated iOS or infotainment firmware.
Bluetooth cache or pairing conflicts.
Interference from other devices or networks.
Check your iPhone and car model support Bluetooth.
Ensure iPhone runs iOS 14 or later for most car systems.
Refer to your car manual for compatible devices.
AvNexo Tip: U.S. cars manufactured after 2015 generally support iPhone Bluetooth audio, calls, and Siri integration.
Turn off the iPhone and car system.
Wait 30 seconds and power them back on.
Attempt pairing again.
This resolves temporary software glitches that block connections.
iPhone: Settings → Bluetooth → Tap info (i) next to car → Forget This Device.
Car: Delete iPhone from the car’s Bluetooth memory.
Re-pair by placing both devices in pairing mode.
AvNexo Tip: Re-pairing clears cached data that often causes connection failures.

Car: Check manufacturer website or app for firmware updates.
Keeping both systems updated ensures compatibility and bug fixes.
iPhone: Settings → General → Reset → Reset Network Settings.
This clears Wi-Fi and Bluetooth caches.
Re-pair your devices afterward.
