Change Bluetooth commands from my car to my phone.

Hi,
It is possible km change the Bluetooth command that my steering well send to my phone?
I use Spotify and when I press the button on my car to skip use music, the Spotify only stop the music... It is possible to change the 'signal' to a different one?

No IR blaster, send IR commands with laser autofocus?

Would it be possible to control the laser autofocus, considering it uses IR to do so, and instead of measuring distance, send IR commands to mimic an IR blaster?
