- TT: Some customers may experience echoing on the line calling the vehicle when using Bluetooth Hands Free. This is caused by the phone Hands Free volume being too low. These settings may need to be reapplied any time the phone is paired to a new head unit, a phone update is applied, or the phone is un-paired and re-paired.
