Kim,

Basic DGPS is a system that calcuates the error (induced or other) in the received satellite signals and then broadcasts a correction code that can be used as input in a regular GPS to modify the received signals for better accuraccy.

A GPS that is DPGS compatible will have a serial input that allows the DGPS receiver (or RDS receiver) to send the serial correction information it. I don't believe that the low-cost 1st gen unit is compatible (a quick check of the Delorme site shows no DGPS capability).

Certainly the RDS data stream which is outputed by the tuner module and (the appropriate) information displayed on the empeg's screen could certainly be used to create a serial data stream for the DGPS capable unit.

(gotta run - plane just closed it's door!)
