Garmin 2730 audio connection to Autocom
I was considering a 2720, but the 2730 would let me replace my XM radio and just have one gizmo on my BMR CoPilot shelf. If this had come out before I sprung for the iPod and iceLink, I'd have saved some bucks. Now that I have the iPod, the 2730's MP3 player is not essential but might be worth playing with.
According to what I've seen, the 2730 power plug does not pick up audio. Instead, there is a jack on the side of the 2730. You can either use this as a "line out" for audio, or you can use a built-in wireless FM modulator; if you did the latter I guess the voice prompts would play over your FM radio.
I have a Garmin power/audio cable and SP mount already installed. The plan was to run a cable from the audio cable jack down to the "priority" port on the Autocom (the one the phone plugs into, that way GPS voice prompts override music). I suppose now I would run the cord from the Autocom to the jack on the side of the 2730.
If you do that, and play XM radio or the MP3 player, would the music output run into the Autocom? That would bypass the onboard stereo controls. If 'audio out" is all audio (voice prompts and music), that may just be how it works.
If the other audio out setting is by enabling the FM modulator, I guess you could do it that way, but that would mean leaving FM radio on to get voice prompts. So no voice prompts when running CD/iceLink/cassette? Also, you have to deal with the limitations of a wireless FM modulator, which some don't like (I only use my XM's wireless modulator in the house and it works OK but I don't drive my house through the mountains).
I use a hardwired FM modulator now. Since it pipes the XM output directly into the stereo system, I thought perhaps I could plug the modulator directly to the 2730, saving a little money on Autocom cable and splitter. Not sure that'll work, though, since the modulator powers on when the XM SkiFi is turned on, and I would be getting rid of that receiver.
I'm hoping someone with a 2730 has figured this out.
