From another web site discussion there has been a lot of angst about the GMA240.
" if it is wired for stereo and you plug in a mono headset it can blow the internal fuses. This is poor design, modern electronics are "short circuit proof". Other brands don't have this problem, nor does my home-built audio panel."
In US said to be $250-00 Garmin repair cost.
