9) When MOTA (Map update Over The Air) is conducted, the map display goes blank (white)
temporarily. In case the customer terminates the MOTA when in this condition, the map stays
blank (white). See NOTE 1 below.
10) Hands Free conversation volume not loud enough compared to the audio volume (unfavorable
balance). See NOTE 2 below.
11) Added function for SXM Weather Alert setup. See NOTE 3 below.
NOTE 1: The MOTA operation is performed in two steps, i.e., Downloading (download the map
data to the H/U via Wi-Fi) and Overwriting (replace the map data to new one inside the H/U.)
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
this condition. After the Ver. 6 software is installed, the map does not turn to blank (white) during
Downloading. However, the map still turns to blank (white) during the Overwriting process, which is
a normal operating characteristic.
NOTE 2: To meet with customer expectations, Ver. 6 software will increase the Hands-Free
conversation volume by 6dB against the base audio volume. Customers will now be able to hear
Hands Free conversation volume which used to be at audio volume level 30 at level 22 after installing
this update. If the customer prefers the original Hands-Free conversation volume setting, it can
be manually adjusted by following: Home >> Settings >> Sound Tab >> Phone Volume >> then
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.
Conditions Addressed By Update #3:
1) Steering wheel satellite switches (other than volume control) and head unit hard buttons (other
than volume control) may become inoperative at times.
2) For Crosstrek Hybrid, the charging scheduler function has been eliminated.
Conditions Addressed By Update #2:
1) AM/FM radio station presets are lost.
2) Favorite Phone Contacts list is lost.
