So, I have been looking for a chart plotter for my new to me O'day 302 and as usual spend forever trying to decide what to get. After comparing 1000 features online for what seems like weeks, I walked into the store and found a Garmin
546 that was in good shape (returned for a bigger model) and got a good deal on it. For once I decided I didn't need the best of the best and thought I had found a great unit at a great price
and that I should be happy with it.
However, after getting home and once again looking online, I realized that a couple of people have written about the magnetic door that covers the SD card slot. So, I go and check mine and sure enough, there is a magnetic mechanism that keeps the card slot door closed.
My boat is a couple of hours away right now and I can't check, but I was wondering if anyone had any experience mounting this chart plotter on their binnacle and if it interfered with the compass
Wondering if I should return it or not.
