OnStar with Text Telephone Capability (TTY)
General Motors is pleased to announce that the safety and security of OnStar  is now available to our deaf, hard of hearing and speech impaired customers. The current  vehicles listed above, as well as forthcoming vehicles equipped with OnStar hardware
 version 7.0 or higher, have the ability to utilize texting telephones. Vehicle specific  TTY capability can be determined by utilizing the VIN lookup Tool. Additional information  may be found by referring to  www.onstar.com/tty
  
.
TTY equipment allows people who are deaf, hard of hearing or speech impaired,  in-vehicle access to 911 and basic OnStar® services by pressing the OnStar®  blue button or red emergency button. The keypad provides a means to communicate by  allowing
customers to type messages back and forth, with an OnStar® advisor or  other party when using the OnStar® Hands-Free Calling feature. A TTY is required  at both ends of the conversation in order to communicate. OnStar® Turn by Turn  Navigation and
Virtual Advisor are not available with the addition of TTY.
The Reimbursement Program
This equipment will be made available to eligible customers through GM Mobility  and OnStar®. Under this program, the customer must complete a GM Mobility application  form. To take advantage of the program, vehicles must be adapted at the time of
delivery  for purchase / lease and a dealer claim ($1, 000 Maximum per GM Mobility guidelines)  with the application form submitted to GM Mobility. Saab dealers must fax documents  to (248)577-7320. GM Dealers will receive electronic reimbursement
directly from  GM Mobility. Saab dealers will receive a check directly from OnStar®. Additional  questions or concerns should be directed to the OnStar Dealer Center at 1-(888) 667-8271  prompt #2.
