Scott - another question along these lines - I just purchased (from Argent) a GPS18 with the 3 conductor plug and wired it up to a T2-135 in my daughter's truck. The T2 is behaving as if it doesn't have a valid position (transmitting profile 2, which I have set up to do when it's stopped OR sees invalid position). Do the GPS18's come from the factory in Garmin or NMEA mode?
Thanks! Clay N7QNM
