Built-in telematics hardware is available on all GM vehicles equipped with the OnStar feature (an active subscription with OnStar is not required). Typically, this includes models manufactured from 2015.
In order to connect to a GM OEM vehicle, you need to have a GM assigned Fleet Account Number, also known as a FAN code. Check the GM Fleet Eligibility web page to see if you qualify for a GM FAN code.
