Mesmerize (USCC) will disconnect bluetooth after hanging up from handsfree call on my Chevy Equinox (2011). Phone vibrates once, after about 10 sec. from hanging up, then vibrates 2x, about 5 sec. after 1st vibration, then disconnects. I've paired & connected other phones to Equinox - no disconnect problems. I've paired & connect Mesmerize to Mazda 6 - no disconnect problems. Have taken Equinox to dealer & they said it was working fine. I've had phone replaced from USCC. Any suggestions, ideas, etc. is greatly appreciated.
