Anyone have any experience with their audio/NAV unit cutting out? Recently on my morning commute, the audio/nav unit will seemingly power off and reset when I depress the brake more than gently. I have not noticed this in the afternoons when it warms up but I would believe the issue to be more electrical than temperature related. The coincidence with the brake application has me scratching my head but that's why I came here to ask if anyone has experienced similar issues. LC is a 2008 with about 110k on the odo.
