I had a 798 at the bow and a 997 on the console. I purchased a used 997 for the bow and had my dealer replace the 798 with it. The antenna was hooked directly to the interlink. After the 997 replaced the 798, I was unable to get a GPS signal. The accessory test screen said the GPS and the interlink were unconnected. Since I have a bow and transom antenna, I asked them to hook the antennas to each individual unit and then to the interlink. We did this and now only the interlink is unconnected. The tech thinks the interlink is bad or it is not getting power. It worked fine before the 798/997 switch. He also asked how the interlink gets power. Any help is appreciated. Sorry for the long post.
