streaming is not affected).

1. Verify that the customer’s MMI requires the
software update by going to the Main Menu
>> Setup MMI >> Version Information
(Figure 2) and ensure the Software version
is less than 0539 (Can be P0533 or K0533,
where P = production software and K =
Kunden or Customer update).

2. Obtain the SD card from the parts department (see Required Parts and Tools) and follow all instructions in
TSB 2047812: 00 SD Creator: How to setup and use the SD Creator for obtaining vehicle software updates
via the MirrorServer.
