Zumo/Cardo Teamset/Sprint Katana Combo
Figured I'd get this out before it slips my memory.
Bought the Zumo 550 in January and added the Cardo Teamset a month or so later.
Had no luck at all using the three devices paired as advertised. Phone to Zumo was fine in the car cradle as a speaker phone. Zumo to most any headset was iffy at best.
Spent much time and learned a lot about the Zumo over at zumoforums.com but never got the problem solved. New phone was suggested even though I've tried three different models. I diligently installed the newest firmware hoping that'd be the fix.
Finally, a tech support person at Garmin offered some older BT firmware versions and it seems version 2.4 is going to work.
So, contrary to the upgrade thinking, if you're having BT problems, a downgrade or two may be helpful.
