I recently completed the installation of my raymarine pro 4 gps/fishfinder with DVI. I fabricated a mount bracket out of aluminum (primed/painted) and mounted it between the ski and step bar. I ran the cable underneath the seat. I purchased a suction ram mount (short) and it holds extremely well on the glove box lid. When not in use, I store the cable (zip tied) in the hull (2007 Sea Doo GTI SE 130).
