In one embodiment, a user selects a primary component of a multimedia system to be configured in a configuration user interface of a mobile device. The configuration user interface of the mobile device displays a photo-realistic depiction of a back panel of the primary component. The photo-realistic depiction of a back panel includes photo-realistic depictions of connection ports located thereon. The user selects another component to be connected to the primary component. One or more classes of potential connections are determined between the another component and the primary component, and for each class of potential connection, the configuration user interface on the mobile device graphically guides the user to select a particular connection port on the photo-realistic depiction of the back panel of the primary component for the class of potential connection. Based on selections of particular connection ports from the user, a set of configuration data is generated.
