Condition Other symptoms may occur immediately prior to the reboot might include an echo in a Bluetooth phone call that eventually drops the call to the handset, or the radio may be non-responsive to touch or hard button inputs. This condition seems to occur much more frequently while CarPlay is in use, but a reset can also occur outside of CarPlay use, with other device brands, or with no device connected. While the condition is very intermittent and di cult to reproduce, when this condition occurs it will always end in the radio doing a hard reset or reboot resulting in the splash animation playing again. Cause This condition may be induced by externally connected devices or by software anomalies. Correction Engineering has identi ed possible causes of this condition and are working on software enhancements to resolve this and other possible software anomalies. Service Procedure: Note: A hard reset is when the radio shuts down and reboots displaying the myBrand splash animation (just as the radio does when the ignition is rst turned on). Similar, but unrelated symptoms could occur with a soft reset. Those are NOT related to this PI. A hard reset occurs quickly, generally in a matter of seconds, not lasting longer than one minute. A soft reset occurs when the radio seems to shut o , but resets to the previous display page. It may show a working / thinking / scrolling circle as it resets, but it will not show splash animation in a soft reset. This PI ONLY applies if the symptoms are immediately followed by a hard reset with splash animation. Con rm with the customer that this condition exhibits a hard reset with splash animation. Please document any speci cs of what was being done prior to, or led up to, the symptoms beginning and submit a Field Product Report with that information. If it occurs at any other time, or if there is not a hard reset, then this PI does not apply and the technician should continue their diagnosis of the customer’s concerns.
