Is it possible to disable the Aux In function on the radio screen (Bolero MIB1)? I have disabled the AM frequency band on the radio (using OBDeleven) and I wondered if this process can be done on the Aux In?

I use both Bluetooth and the SD Card option for music, but never the Aux In, and it would be easier to toggle between two options rather than three.
 

It can. 

 

1 - Module 5F - Electronic Information 1. Code (20103)

2 - Extended Code (Text mode)

3 - Byte 8 AUX-IN

4 - Select one of the two options:

- On (default)

- Off (tick this one)

Thanks @SashaGrace, just the ticket!
