Bose Sound System update

Standard install has BOSE updates REMOVED.

By default, the AIO FW will not update the Bose amplifier firmware. metainfo2.txt was prepared to skip this component.
Updating will require parameterization of the amplifier, which must be completed with PIWIS or at the dealer.

⚠️ Without the parameterization you will have no sound.

If you wish to update Bose you can use different metainfo2.txt, which is included into the IO package.

1. Remove metainfo2.txt
   
2. Rename metainfo2-Bose.txt to metainfo2.txt
   
3. Run the update
   
4. Perform parametrization
   

SVM fix

Use built-in M.I.B AIO version to run SVM fix.
Enter GEM (CAR+TUNER buttons on home screen) and select function.
