Take your time make sure not bent or broken pines on the connectors. Have you checked the device list on all your units sometimes the issue stops in one place while it works in others. That can give you a clue as to where the bad part is. For get the BS downloads everyone tha usese this has some kind of issues and use the sd card download to your units by the card. Best way least issues just the facts not dogging on Tech. Did you install your NMEA? if so can you diagram how is layed out and terminated.
