Procedure notes
This is how to pair your iPhone or Android phone to a 2021 Toyota 4Runner. Generally, pairing a Bluetooth compatible phone to your car will allow you to make handsfree calls. In many models, you can also play music through a paired device over the Bluetooth connection too. Check your owners manual to see if this is possible in your 2021 4Runner. Some models only allow Bluetooth devices to take calls wirelessly and do not support Bluetooth music. Typically, these cars will require an input jack to play music from your phone.
Do you have Bluetooth problems? Is Sync not working in your 4Runner? Or are you having Bluetooth issues? The steps needed to sync your phone to your car tend to vary substantially from one vehicle to the next. If you followed the steps in the video above and your a 2021 4Runner will not connect to your phone, then you may need to delete some saved phones. Used cars will often have several saved phones in them. Once a maximum number has been reached, the 4Runner will not allow additional devices to be paired without deleting some first. If your 2021 Toyota 4Runner requires a password, try 1234, 0000 or ABCD.
