Has anybody installed an Axxess ASWC-1 steering wheel control interface for an aftermarket head unit into their Civic with an i-MID? I'm curious if this removes all ability to control the factory system, or if there's some sort of toggle to switch between controlling the head unit and factory controls. There are a handful of functions I don't want to give up access to for the sake of convenience with a new HU, but if there's some sort of toggle I'd be okay with it. Any advice appreciated. For reference, I have a 2012 Civic Coupe LX and looking to add one of the Pioneer NEX HUs for the CarPlay functionality coming sometime this summer.
