I just purchased a GP33 which I connected to the N2K backbone. I was told that it would recognize the Garmin GPS antenna that currently supplies the MFD 8 and the RD33 with their position information. The MFD 8 and RD33 had no problem at all talking to the Garmin antenna but the GP 33 has no signal at all. The GP 33 fires up okay and all displays are present. Do I have to attach the Furuno antenna that it came with to make it work or is their a setting somewhere that I have missed. I have read the owners manual but cannot see anything about this topic. Thanks.
