Using ALP Radio Mute and Control Functions

[ApexOnYou]

What car are you installing this on? I know with the BMW "telematics mute" radio wire the ALP works fine without isolation. If you are concerned just throw a diode on the trigger wire - stripe side towards the ALP ground output. Much easier than a relay.

It is a 2002 Porsche 911 with the OEM Bose system. I like you idea about using a diode, seems much cleaner. Thank you.
