Before updating the software to Ver. 6, the map screen turns blank (white) during the Downloading
process until it is completed. If the customer stops (by turning off the H/U,) during the Downloading
process, the map display will stay in blank condition. The MOTA operation can be restarted even in

lowering the volume 6 - 8 steps.
The base audio volume setting chosen at the Factory Data Reset is at level 22 compared to the
previous setting, which is level 30. (This means customers will no longer have to adjust the base
audio volume to get comfortable Hands-Free conversation volume.)
NOTE 3: Added function for SXM Weather Alert is only applicable to HIGH grade head unit.
