Originally bought one for use with my OpenTracker and it was flawless. When I upgraded to a TM-D710, I soldered the cable supplied with the -D710 to a mating DB-9, added an LM-7805 voltage regulator (inside the DB-9 shell) and away I went. It was plug-and-play on the first try! The receiver regularly receives 9 or more satellites mounted (with double sided tape) inside the rear window of my Ford Ranger. Great value for the $$
