Update my MMI Audi Q7 2016

[mousxsat]

Dear Team

I want to update my MMI in order to activate Android auto on my car which is runing under MHI2_ER_AUG22_S2133 and afterwards update my maps that it is on 2019.
Some people told me to follow these step :

1. Update the FW using the MHI2_ER_AUG22_K2161 downloaded from mibsolution
2. After the FW's update, download the MIB and the patches from mibsolution and run it to my MMI

After I could upgrade my maps as the FEC 23000EE will be installed with the MIB.
Before doing anything I would like to have your advice if this is correct because I'm totally new

Thanks in advance
