'17 L Replacing Head Unit w/ Programmable Convenience Features
I didn't see an audio section, so...
The nice-sounding but none too powerful four speaker stereo in my '17 L has programming for convenience features built into the head unit. How would one upgrade it in this situation without losing the ability to program those features?
