I was driving from California to the Phoenix area to visit my youngest daughter and about 4 hours into the drive I took my Motorola H700 off and stuck it between my legs, it was starting to bother my ear. An hour or so later I called my son in-law for directions and had a problem...the screen said "connected" but nothing was coming out, no sound. So I hung up and tried again...same thing. This went on for several calls when all of a sudden he called me, ah, I thought now I got him. Still nothing. So I decided to put it on speaker phone since I was driving and lo and behold it worked great! I got the directions I needed and hung up...then I noticed the cute little blue light blinking to tell me the bluetooth was synced , well duh, it's kinda hard to talk on the phone with the H700 still between my legs. DOH! Sometimes it amazes me how dumb I can be.
