Boot / Trunk Handle Button not working since install of Aucar headunit

Hi,

Same as the thread below. Dash button opens boot. Remote Key button opens boot. Boot handle does not open boot.

I have bought a new handle and micro-switch. Then I tested both with a multimeter - they both work fine…. (Yep - got the order wrong with the testing and wasted money but we both drive a Maserati so please don’t judge me!)

I answered this exact issue yesterday.

Aucar Trunk Won't Open

You are a legend sir!!
Vehicle Settings - “Independent trunk lid unlocking“ - un-tick to allow the boot switch to work.

Thank you @onlinealias

Try doing a component relearn, then open and closing the door locks with the center console door lock buttons.
