I came up with a low-cost (less than $6) solution to put Garmin audio into my helmet.
Parts:
1. 8-Ohm Mini Speaker (273-092) from Radio Shack $2.59
2. 1/8" (2.5mm) Mono Phone Plug (274-286) from Radio Shack $2.99
3. ~3' of wire
4. A bit of heat-shrink tubing to make things pretty
5. A plastic 35mm film canister, cut to hold the speaker
6. A couple dabs of glue from the hot glue gun to hold it together
The speaker is rated at 0.1 watts, whereas I was told that the speaker in the 12V adapter is 0.5 watts. On level 5/6 on my 2610 works for me with no problems. The wire I'm using is from an old set of headphones, and has a bit of resistance of its own so this probably helps.
The film canister was designed to protect the speaker's diaphragm. The speaker goes in diaphragm first. The back of the mini-speaker comes covered with a thin cloth-like material, so sound can still come out the back.
I'm very pleased with how well this works.
