Bluetooth Connectivity Issues
Software Incompatibility with iOS Updates
One of the main culprits behind iPhone and BMW Bluetooth problems is software incompatibility, especially after iOS updates. When Apple releases new iOS updates, they can introduce changes that disrupt Bluetooth software in older BMW models, leading to communication issues between the devices. For example, users have reported that their iPhone fails to connect to the Bluetooth system in their BMW following an iOS update (BMWGeeks). Ensuring both your car’s Bluetooth software and your iPhone’s software are up to date can sometimes solve these connectivity issues.
Signal Interference and Frequency Band
Bluetooth connectivity can also be disrupted by signal interference from other electronic devices or a crowded frequency band. Many common household electronics, such as Wi-Fi routers, microwaves, and baby monitors, operate on similar frequency bands to Bluetooth. This can cause interference, resulting in connectivity issues between your iPhone and BMW’s Bluetooth system.
If your BMW’s Bluetooth keeps disconnecting, it might be due to such interferences, software glitches, or a problem with the Audio/Video Remote Control Profile (AVRCP) version. The AVRCP version plays a role in sending commands between devices to control playback. If there’s a mismatch in versions, it can lead to disconnections. Updating either your phone or BMW’s software to ensure compatibility can help alleviate this problem (BimmerTech).

Understanding these common connectivity issues can help BMW owners take the necessary steps to maintain a stable Bluetooth connection in their vehicles.
Troubleshooting Bluetooth Problems
Low Battery Impact on Connectivity
A low battery on either the iPhone or the BMW can lead to Bluetooth connectivity issues. Ensuring that both devices have adequate charge can resolve these issues (BMWGeeks).
| Device | Recommended Battery Level |
|---|---|
| iPhone | Above 20% |
| BMW | Regular maintenance of battery levels |
Low battery issues can also affect other BMW features, such as bmw key fob not working properly.
Advanced Troubleshooting Methods
If basic troubleshooting steps like restarting devices and toggling Bluetooth off and on do not work, more advanced methods may be necessary to resolve Bluetooth connectivity issues between iPhone and BMW.
- Reset Network Settings on iPhone: Go to Settings > General > Reset > Reset Network Settings.
- Reboot Car’s Infotainment System: Follow the manual specific to the BMW model to reboot the system.
- Software Updates: Ensure both the iPhone and BMW software are up-to-date.
For further assistance, some users suggest reaching out to Apple Support if steps like toggling Bluetooth, forgetting and reconnecting devices, or renaming the iPhone fail.
Additionally, referring to bmw remote software upgrade not installing can provide more information on keeping the car software updated.
Specific Connectivity Issues
Bluetooth connectivity can be disrupted by signal interference from other electronic devices or a crowded frequency band, leading to connectivity issues between iPhone and BMW Bluetooth systems.
| Issue | Potential Cause | Solution |
|---|---|---|
| Frequent Disconnections | Signal Interference | Avoid other electronic devices |
| Can’t Pair | Firmware Issues | Update Firmware |

iPhone 12 Pro Bluetooth Problems
Issues with BMW e90 (2011 328i)
Owners of the iPhone 12 Pro have reported significant Bluetooth connectivity issues with their BMW e90 (2011 328i). Despite earlier iPhone versions like the iPhone XR connecting successfully, the iPhone 12 Pro faces persistent glitches. Software incompatibility, especially after iOS updates, is one of the primary culprits behind these complications (BMWGeeks). Users have encountered dropped connections and the inability to maintain a stable link, even when using voice commands or Siri.
Troubleshooting Experiences
Many users have attempted various troubleshooting methods to no avail:
- Restarting both the iPhone and the car’s infotainment system.
- Turning Bluetooth off and on.
- Resetting network settings on the iPhone.
Despite these efforts, the Bluetooth connectivity problem persists. Advanced troubleshooting steps, such as resetting the infotainment system in the BMW, may provide a solution. However, the likelihood of resolving the issue with a software update from BMW is slim since these updates are typically available only for vehicles with navigation systems (Apple Support).
Manufacturer Hardware Differences
One underlying cause seems to be differences in the Bluetooth hardware used by manufacturers. The Bluetooth 5.0 protocol of the iPhone 12 Pro introduces changes that may not be compatible with the older Bluetooth modules in BMW’s e90 generation. The hardware differences between previous iPhone models and the iPhone 12 Pro could lead to the connectivity issues observed (Apple Support).

Common Bluetooth Problems
BMW owners often encounter various Bluetooth issues. Here, we address common problems such as music not playing, audio connectivity failure, and poor voice quality.
Music Not Playing
One common problem is when Bluetooth is connected, but music does not play, resulting in silence. This could be due to smartphone settings, audio streaming configurations, or connection conflicts with other devices trying to connect to the BMW’s iDrive via Bluetooth (BimmerTech).
To troubleshoot this issue:
- Check your smartphone’s Bluetooth settings and ensure it is set to stream audio.
- Go to the iDrive system’s Bluetooth menu and verify that the correct device is selected for audio playback.
- Disconnect any other devices that may be interfering with the connection.
Audio Connectivity Failure
Another issue is BMW Bluetooth audio not functioning correctly, which may require checking that the iDrive system is set up for Bluetooth telephony from the device, inspecting for BMW Bluetooth pairing problems, or making sure there is no connection conflict with other devices (BimmerTech).
| Connectivity Check | Status |
|---|---|
| iDrive system setup for Bluetooth telephony | Confirmed |
| Bluetooth pairing issues | Inspected |
| Connection conflicts | Resolved |
