Garmin 2820 audio out cable question
I'm installing the 2820 and the cable supplied has two connections. Main connection goes to the 2820 for power and there is a SECOND CABLE MARKED 2.5mm MONO HEADSET CONNECTOR.
I want audio to go to my headset, via my AutoComm intercom. How do I make this connection?
My previously installed StreetPilot III had the same size cable output jack 2.5mm that connected directly to my intercom. It seems like I can plug this same cable into my new 2820? If so, why the SECOND CABLE MARKED 2.5mm MONO HEADSET CONNECTOR? In the future I might want to use the XM satellite feature, but for now it is not installed. Cell phone connection is also in the future, but not now. Since the bike is naked, I'm open to suggestions. I've read previous threads, But am still confused, perplexed and scratching my head! HELP !!!! Please.
