Garmin to intercom connection woes

[rdover]

After 13k miles of problem I finally got the soldering iron out - I have failed!

I have a 12GSA with a Garmin 2720 and a Starcom1 intercom. The Garmin speaker connection has a silly little 2.5mm jack socket that cannot cope with the constant vibration on a bike and is IMHO a porr bit of design from Garmin.

Anyway, I have replaced the cable twice and still I get irritating crackles and dropouts so last night I lost the will to fix it and hard wired the wee shit into the intercom.

I told Starcom1 about it (not their fault in any way but it could offer them an explanation for other problems) and written to Garmin (not expecting a reply).

It's a simple job to to:
Cut off the socket to find 4 wires.
Brown = live
White = earth
others are not used.

20 secs of soldering, 1" of shrinkwrap and perfectly clear bleating from the irritating woman-in-a-box.

I think you'll find that's what most of us do, regardless of brand of intercom unit.

We just don't wait 13K miles to do it.

Sorry to sound numb, but which bit did you open up for surgery, the intercom or the 2720?

Got any pictures

The garmin cable has a socket and the Starcom cable has a plug. Remove both, strip wires and solder together as above.

Mine was working OK and as I swap the intercom from bike to truck (as will be doing this afternoon) it means I don't have lots of loose wires hanging around the bike but it's better to be reliable!
