Its my understanding that the AIS cannot share GPS with a MFD. That is why I purchased the Vesper XB6000 with an internal GPS antenna. Initially I dreaded mounting another antenna and I was concerned that the boat would look like a NASA tracking station. Since the boat is torn apart I might as well run another cable for the GPS antenna included with the XB6000. I'll mount it on the roof rack rail forward of the AIS antenna. This will only require one more hole for the cable. When done there will be a total of seven antennas plus radar! (2 GPS, TV, WIFI booster, AIS,VHF, and Sirius/XM).
I posted pictures of my progress in my photo album. Knotifying was right, the screws to the valance are recessed under the curtain track. (Thanks). Once the valance was removed I removed the screws holding the headliner. I could not pull it down enough to expose the side of the roof so I had to remove the forward port hatch trim. That provided relatively good exposure to the side. It was a pinch getting my hand in there to apply the nuts and washers. I stood on the co pilot seat and was able to stand up through the hatch and hold a screwdriver on the outside while tightening with a wrench on the inside. I was so proud of myself until I realized I had the mount base upside down. That means the release lever is inboard. It works fine and I can live with that- lesson learned! I try to think these things thru but sometimes my ADD gets in the way :roll:. Next I will run the cables over the headliner on the starboard side down to the aft end of the cave. The wood side panel next to the settee is easy to remove. I'll provide another update when I get it all done. My only concern is that I didn't draw any blood. Thats a bad omen but there's still time.
