Just up graded to a GP 7000 chart plotter w/ C-Map NT Max on a SD card from a GP 1850D that I had changed from classic charts to C-Map NT on the FP card. The antenna on the GP1850D was a GPA 019 and runs thru the hard top tubing and overhead electronics box so its a pain to remove it, the 7000 came with a GPA 017 antenna I looked at the price difference between the two and the GPA 019 is a lot more expensive. The GP 1850D uses either the GPA017, GPA018 or GPA019 antenna, the GP 7000 manual only shows the GPA 017 antenna for that model. Will I get better results keeping the GPA 019 that's installed on the hardtop with out having to rewire half the boat also.
