Abstract: An adaptor for supporting and connecting a portable electronic device, such as a portable phone, computer or other wireless communication device. The adaptor includes a pocket member and an interface module. The portable phone mechanically and electrically connects to the pocket member, and the pocket member mechanically and electrically connects to the interface module. The mechanical and electrical connections between the pocket member and the interface module are common between any interface module and any pocket member. In contrast, the receiving section of the pocket member is varied between different pocket members to accommodate portable electronic devices having different physical constructions. The pocket member attaches to the interface module with a limited, one-dimensional movement of the pocket member relative to the interface module to optimize use of space, particularly in vehicles.
