Case for a portable electronic device having an interface to provide for transmission of data bewteen the portable electronic device and an external device

A case for a portable electronic device including a first surface, a second surface, and sides between the front surface and the back surface, wherein the portable electronic device includes an input socket and is adapted to electrically connect to an external electronic device and wherein the case is adapted to attach to an external structure, comprising:

• a cover portion having an inner surface and outer surface, wherein the inner surface is adapted to couple to the first surface of the portable electronic device;
• a first interface at a first location on the cover portion adapted to electrically couple to the input jack of the portable electronic device;
• a second interface at a second location on the cover to electrically couple to the external electronic device;
• an attachment structure formed on the outer surface of the cover portion and adapted to attach the cover portion to the external structure, wherein the external electronic device is electrically coupled to the second interface when the external structure is coupled to the attachment structure;
• and
• a cable coupled to the first and second interfaces adapted to transmit data between the first interface and the second interface.
