I pulled the ADF out of the 185 a few years ago. Even though going through Canada to AK and back might allow its use, I found myself only using it for talk radio. With GPS and no interest in going IFR (I do that enough at work to satisfy any cravings), I decided to lighten the EW by 10#.
Fixed card or RMI, I always enjoyed doing an NDB approach, but there is no practical need for it anymore, at least in my world. The indicator does make a nostalgic bookend, though.
