If your vehicle is equipped and your phone is connected through available Bluetooth† and you are having issues with the phone disconnecting, calls breaking up or calls sounding distorted, here are some possible solutions.
Sometimes, you may have trouble with Bluetooth because your phone’s software is out of date. So, if you’ve already checked if your phone is compatible using the Bluetooth Device Compatibility Guide, the next step is to make sure you have the latest software version updated on your phone.
If your phone still disconnects, your cellular signal may not be strong enough. See if the problem persists when your signal is stronger.
Also, if you are on a call when the engine is off, the vehicle may time out of accessory mode to save the battery. When this happens, the connection between your phone and the vehicle will disconnect and the call will be transferred back to your phone.
Here are some possible causes and remedies:
Call volume is determined by both the volume setting on your phone and the audio system’s volume. To adjust:
Once you end a phone call, you may need to readjust the audio system’s volume.
There are several factors that may affect your Bluetooth call performance. A problem may be caused by your phone’s or vehicle infotainment system’s software. Be sure you have the latest software version for your phone. If you’ve updated your phone and are still experiencing Bluetooth calling concerns, try deleting your phone’s pairing and then pairing it again.
Select the phone or vehicle you’d like to connect. In most vehicles, you can only have one active Bluetooth connection at a time when your vehicle is on. Check your phone’s and vehicle’s paired devices lists to see which phone is active. The system defaults to the last paired device used in your vehicle. If that device isn’t active, it goes down the list of paired devices until it finds one that is active.
Check your phone’s and vehicle’s paired devices lists to ensure that the connection is active. If it is in one of these lists but is not active, simply select the phone or vehicle you’d like to connect. If you are still experiencing issues, you will need to delete and pair again by following the initial pairing instructions.
Delete the phone that is no longer in use from your vehicle’s paired devices list.
When you pair a phone with a vehicle, it involves a process of exchanging security credentials to allow your vehicle to gain access to it. An encryption key is generated and if the key is lost by either your phone or the vehicle, they may need to be paired with each other again. Follow the instructions for How to Pair Your Bluetooth Smartphone.
