Default NMEA 2K VHF installation

I always wanted the NMEA 2K connection for the VHF, so I just purchased the Lowrance Link-8. When I connected it to the NMEA backbone, the GPS lost it's GPS antenna signal, and the radio displayed "No GPS Data". I disconnected the NMEA lead from the radio, and the GPS (Garmin 7212) regained signal.
I am doing something wrong here, but I can't figure out what!

If you have an extra T connector then try to use it in place of the one you connected the radio to. I would also try a different drop cable to the radio. If it still won't work after that then you likely have a short of some sort in your N2K circuity on the VHF.

This probably goes without saying, but you connected the VHF drop cable to the T on the backbone, not to the end of the backbone itself, right?

Thanks for the input ... it was indeed the drop cable! Just bought it, and should have checked, 4 wire not five!! All working just fine!
