Charlie,
Thanks.
Have to decide if I want to pull the trigger and get the helmet and bluetooth set up. Feel like I'm not using all the capabilities of the Zumo not having it.
I sometimes forget to turn off Zumo (ignition on bike) when I want to place/receive a call and person on the other end can't hear me when the phone is "bluetooth" connected to the Zumo.

Ride Safe,

Gary,
I think you'll like the capabilities that having the 3/4 will give you. I like the fact that I have the intercom (when I have my better half riding with me), GPS, and CB (if on), coming through the helmet speakers, and having the music coming through the bike speakers. I know you won't have that flexibility with the Zumo, although I believe there is a switch box you can buy (can't remember the company, NADY, I think), that you can route your GPS, or anything else you want, to the helmet. I'm thinking about buying the bluetooth module for my SEUC, so that I can call hands free.
Cheers
