This was asked for a while ago, mainly due to issues when trying to use Garmin 660/665 GPS. I see it was added to the 20S. Can it be added to SMH-10 and what about 10C?
I have a garmin zumo 665, a smartphone, and SMH-10B. I like to listen to A2DP sources from my phone including pandora, mp3 from media player, slingbox, and have been experimenting with FM radio...
