I finished the GPS install on the 22 Dauntless. Unlike the 18 Dauntless, the wiring is a little more difficult because Whaler doesn't provide a hot (red side) bus bar to tap into. The only bus bar present is the black ground. Go figure. Obviously, getting a ground was easy. Since the center seat livewell is not used on this boat, I simply took power from the hotside of that switch.The GPS antennas (XM Weather Data & GPS) were mounted on the front corners of the center console. I removed the plexiglass windshield to make drilling the holes easier. The antennas were mounted to four inch stainless steel antenna posts purchased from West Marine. The antenna cables were run above the headliner inside the center console. The headliner is removed by popping off the screw caps to access the phillips screws holding the headliner up. I then had to drill a hole to get the antenna cables through to behind the instrument console.
The XM Weather Data receiver was mounted behind the fire extinguisher underneath the instrument panel (on the inside). I used the same screw holes that hold the extinguisher bracket.
Since the top of the console was so large, placement of the GPS unit had many options. In the end, I placed the unit just to the right of the speedo and tach about two inches in front of the back edge of the console. Remember that you also need to drill a 1.25 inche hold behind the GPS for cable access underneath.
