Various aspects include audio amplifiers for driving at least one speaker. In some cases, the amplifier includes: a controller for amplifying at least one input signal to provide an amplified audio output signal, the controller configured to operate the amplifier in at least two modes, including: a first mode including a dedicated connection to the at least one speaker; and a second mode including a direct physical connection with an additional audio amplifier and the dedicated connection to the at least one speaker; and an interface switch coupled with the controller that enables a change between the first mode and the second mode, wherein the controller maintains the selection of the first mode or the second mode until a command is received via the interface switch.

Various aspects include audio amplifiers for driving at least one speaker. In some cases, the amplifier includes: a controller for amplifying at least one input signal to provide an amplified audio output signal, the controller configured to operate the amplifier in at least two modes, including: a first mode including a dedicated connection to the at least one speaker; and a second mode including a direct physical connection with an additional audio amplifier and the dedicated connection to the at least one speaker, where in the first mode and the second mode the amplifier is configured to provide the amplified audio output signal to drive the at least one speaker, and in the second mode the amplifier is configured to forward the at least one input signal to enable the additional audio amplifier to control audio output at an additional speaker.

A mobile navigation system includes a graphical display for presentation of map information. Map features are selected for presentation on a display. Characteristics for display are also selected. The characteristics for display include a scale for display that varies across the display. An image for display is generated from the selected features according to a selected scale.
