I have a new Garmin 546 plotter mounted right at my binnacle compass. This is only practical if you open up the unit and remove the internal magnet that is used to keep the SD chip door closed. Garmin was no help when I called them about this, saying this action would void my warranty. They suggested that "the inductance from the display is the main problem." That proved to be untrue and there is no compass deviation from the display with the magnet removed. Notwithstanding this curious design feature the 546 is a good plotter. The binnacle installation is ideal for many boats, and the fact you can pivot and tilt the display for optimum viewing wherever you sit or stand is a great advantage.
The magnet I removed is powerful enough to pick up a good sized wrench. I intend to fasten a strong fishline to it for retrieving tools and miscellaneous parts from my bilge.
