Thanks to GM's TechLink, we know more about the new wi-fi system present in the 2015 Corvette StingRay, Z06 and many other GM vehicles. The following is GM's internal direction to its Technicians, including noting additional PDI components.
OnStar Generation 10 and Wi-Fi
"Faster service and an available Wi-Fi® hotspot are just two of the advantages of the new OnStar Generation 10 system available in many 2015 GM cars and light-duty trucks. The OnStar Gen 10 system uses Global System for Mobile Communication (GSM) to communicate data and voice signals over the national cellular network. The Telematics Communication and Interface Control Module in the vehicle also has the ability to act as a Wireless Local Area Network (WLAN) Wi-Fi hotspot similar to a household wireless router.
The Telematics Communication and Interface Control Module houses an internal WLAN antenna enabling hotspot connectivity and streaming high-speed media to the entertainment system. The module is capable of up to 4G LTE speeds (4G is the fourth generation of mobile telecommunications technology, and LTE, or Long-Term Evolution, is a standard for wireless communication of high-speed data) and houses two technology systems: one to process Global Positioning System (GPS) data and another for cellular information. The module sends and receives all cellular communications over two cellular antennas and cellular antenna coax cables.
Wi-Fi Hotspot
The Telematics Communication Interface Control Module acts as a Wi-Fi hotspot router and provides direct 4G LTE connectivity to the Internet. It has the ability to connect up to seven compatible mobile devices (smartphones, tablets and laptops) at one time. Devices must be WPA2 compliant Consult the device manufacturer for information regarding the WPA2 security protocol and Wi-Fi device compatibility.
An OnStar data plan is required to use the vehicle’s Wi-Fi hotspot. New customers receive a three-month or 3 GB (whichever comes first) trial data plan with the purchase of an eligible 2015 vehicle.
The system uses a secure autoconnect feature between the Telematics Communication Interface Control Module and the radio/Human Machine Interface (HMI). It is always available and ready to connect to a dedicated in-vehicle device. The ignition must be in Run, Accessory or Retained Accessory Power for Wi-Fi to operate.
TIP: The Wi-Fi hotspot has a range of 50 feet (15 meters) from the vehicle.
The coverage for the in-vehicle Wi-Fi hotspot depends on the wireless carrier network coverage. When driving in areas where coverage fluctuates, performance may be impacted. In a 2G-coverage area, the Wi-Fi hotspot will not work. In a 3G-coverage area, streaming data or video to mobile devices may result in the degradation of service. Coverage maps are available on onstar.com.
When the OnStar data plan is activated, a security default password is established for the Wi-Fi connection. There are several ways to change the SSID or password, including by placing a call to the OnStar Call Center, using the Gen 10 mobile app or through the scan tool.
Connecting to Wi-Fi
To connect to the Wi-Fi hotspot, users need to start a Wi-Fi network search on the mobile device, select the vehicle hotspot listed, and then enter the password when prompted.
The “SSID” is the name of the Wi-Fi hotspot for the vehicle, which is used to identify which Wi-Fi hotspot a user connects to.
To retrieve the SSID and password for the hotspot, press the OnStar Voice Command button on the overhead console or rearview mirror, wait for the prompt, and then say “Wi-Fi settings”. The information will be displayed on the infotainment screen.
For assistance or to change the SSID and password, press the blue OnStar button or call 1-888-4-ONSTAR to connect to an OnStar Advisor.
Updates to PDI
The following information regarding OnStar 4G LTE and Wi-Fi has been added to the Pre-Delivery Inspection (PDI) form:
• OnStar hardware check (green light)
• Ensure antenna mast is attached
• Wi-Fi broadcast check – customer hotspot feature
- Press the OnStar Voice Command Button and say “Wi-Fi Settings”
- Using the information on the screen, connect a device
- Using a Wi-Fi enabled device (smartphone, tablet, and/or laptop)
- Verify that you can connect to vehicle’s hotspot.
