Do you have the installation manual for the 300XL? If not, send an email to:How in the world do I check to see if its turned on (channel 1)? I checked the baud rate on the TT and its set at 4800. I tried 9600 and that also did not work. My Lowrance has many options on baud rate. But it also has options on NMEA in, NMEA out, and one other. Only one works for the TT. Guess I better be calling TT or Garmin. I would hate to have to make those changes every time I switch to another gps.
Lucas, are you listening.
Got any ideas how to set the ADI II so the 300xl talks to it? When I push the track button, I get a zero and no heading info.
EDIT: According to Dennis's post, AVIATION is also an option which should work as well.
