1. A communication system for interfacing two devices into a single output of an interface comprising:
- a first receiving device comprising a wireless modem or a transceiver receiving a first plurality of signals, wherein said first plurality of signals comprises a first format;
a second receiving device comprising a GPS receiver receiving a second signal; and
an interface having a microcontroller coupled to the first receiving device and the second receiving device, said interface having an output, said microcontroller coupling a first portion of said first plurality of signals from said first receiving device to the output and receiving said second signal from said second receiving device after said first portion, said microcontroller, reformatting said second signal into said first format, coupling said second signal to the output and thereafter coupling a second portion of the first plurality of signals to the output.

Abstract
An interface system for interfacing to a first receiving device receiving a first plurality of signals and a second receiving device receives a second signal includes a microcontroller coupled to the first receiving device and the second receiving device. The interface has an output. The microcontroller couples a first portion of the first plurality of signals from the first receiving device and receives the second signal after the first portion. The second signal is coupled to the output. Thereafter, the second portion of the first plurality of signals is coupled to the output.
