I've ordered my TZ14 and am trying to get all the interfacing laid out. TZ14 will get GPS from 330B. Need to interface Navpilot 511 w/ TZ14. What is simplest cabling method to get heading info from PG500 to TZ14 and control head information into TZ14 as well. I have ordered the 0183/2000 NMEA2K2 converters. Thanks in advance!
