An in-car navigation device depicts dynamic travel information in the context of a schematic display of the actual roads that the information relates to. The thermostat comprises a microprocessor in communication with the plurality of membrane switches, and has a memory for storing a program for controlling the operation of the climate control system. Each apertures has at least three inwardly protruding members and bights are formed therebetween when the tube associated therewith is lodged in place to establish secondary fluid flow through the support plate. One approach uses the side fire fiber, similar to the one utilized for biomedical optical spectroscopy. Typically, the membrane has a thickness of 90 microns or less, more typically 60 or less, and most typically 30 microns or less. The body may be adapted to be detachably coupled to the existing electrical box such that the outer wall may be adapted to cover and shield a front opening of the existing electrical box from undesirable debris and fluids.
