The Audi connect Gen1 system includes all vehicles that utilize a removable plastic SIM card. The Audi connect Gen2 system includes all vehicles that utilize an embedded SIM card. The root cause of all complaints cannot be attributed to the vehicle hardware because of the backend server configurations that need to be correct in order for Audi connect to work. For most sporadic complaints, the issue typically resides with the MBB backend server or with the source data provider (Google, INRIX, etc.), and not with the vehicle. In rare cases, the mobile network operator (AT&T, T-Mobile) can be the cause of the complaint. For most static complaints, the issue can be attributed to the user account subscription or possibly the vehicle hardware.
