CONDITION# 5.2 

Hurricane or Severe Weather warning message is displayed:

or

CAUSE: 

The head unit is designed to receive severe weather alert information from Sirius XM 

(SXM) and display a pop-up window with the alert message, whenever there is a signal from SXM.  

So far, we are only aware of HIGH grade units to have this feature available.

RECOMMENDATION: 

Please note when there is no date information supplied by SXM, the details 

(dates/ times) will be shown as --/--/---- --/--   in the alert notification message.  The head unit is 

operating as designed when this occurs.  

Effective with the most recent software version update Harman has implemented an enhancement to 

allow user control of some weather alerts from Sirius XM service.  Settings are found under Settings/

General/Sirius XM Settings.  See below.

Please note this feature is available only in HIGH grade units.

CONDITION# 5.2
