A couple of bt observations for anyone interested. As already documented, if you forget to turn off wifi you may have choppy audio and disconnect issues. What I found is that when I leave wifi on, my bluetooth disconnects at the exact same spots is various LIRR stations (Rockville center, Baldwin and Merrick) every time and audio breaks up in conjunction with on train announcements. I originally thought the issues were random, not so. I was able to pair both my Evo and the wifes Epic with our aging Garmin 765t GPS (remove the # from the Garmins bt name), something I was never able to do with the Moment or Pre. You can transfer the phone book with the Evo, not so with the Epic. The Epic looses connection randomly while the Evo is rock solid stable. While investigating the Epic disconnects, I found a bt signal strength meter on the Garmin and it shows the Evo having about twice the signal strength of the Epic. Obviously, if the most important thing for you to do with your smartphone is pairing it with obsolete Garmin models for some very low fidelity handsfree goodness, you should choose the Evo over the Epic.
