Question Garmin 2 wire power cord w/speaker plug

I just received my garmin motorcycle mount for my 2720. Along with the power cable there is a plug for a (I'm guessing) earphone / headphone / ear piece attachment.

My LT is not set up for communication and I am wondering if anybody out there know where I might get a set of head phones that might plug into the garmin plug and be of suitable size to put into a helmet?

I have the same setup on my GS with a 376c. The output from the dongle off the powercord is mono, and is 1/8", so you'll need two adapters - a 1/8 mono male to 1/4 mono female and then a 1/4 mono male to 1/4 stereo female. You can find these at your local Radio Shack for a few bucks.

The hardest part for me was finding the right speakers that fit in the ear and under the helmet. You can go with custom made models that fit in your ear, or you can try off the shelf models. I tried some offerings from aerostitch and wasn't happy with them. I'm currently using the Shure eC4s and I like 'em a lot.

I have the same set-up, and I ran the audio signal from that little plug right into a small external speaker mounted behind the garmin unit. I pointed the speaker straight up so the sound bounces off the windshield and right to me. Works great. I also put a SPDT switch in the speaker housing to move the signal from that speaker to my soon-to-be intercom system.

If you're looking for a cheap and easy way to make regular earbuds, like those that come with the iPod, motorcycle friendly, check this thread. I used these on an 8 mile run yesterday, and they work wonderfully. I also use them at the gym and in the helmet at 85mph with similar results. Very highly recommended!
