A mirror adjustment unit for an exterior mirror (1) comprises a base frame (11) and a mirror support (9). The mirror support is rotatable relative to the base frame via an adjusting mechanism (14a, 14b) including a first and second electrically energizable driving device (15, 16) for rotating the mirror support relative to the base frame with respect to a first and a second axis, respectively. The second axis is perpendicular to the first axis. The first and second driving device have a first and second electrical connector (17, 18), respectively, arranged on the base frame, for electrical connection of the first and the second driving device, respectively, with an on board network (4) of a motor vehicle to which the base frame is connectable. The mirror adjustment unit further has a third connector (22, 23) for electrical connection of a view assist device (19) with the onboard network. The third electrical connector is placed between, and electrically connected with, on one side, the first and second electrical connectors and, on the other side, the view assist device.
