Have a XV600 running the offical release from Verizon for the 2.07 ROM. Includes BT Stack 3900.. We purchased two BT items tonight.. Both Motorola, one is the H350 earpiece and the HF820.. Both pair exactly as they should and ring as they should.. However, neither will send the mic info from the BT piece to the phone.. The person I'm calling cannot hear me.. I can hear them clearly.. Any thoughts? Both items work fine on my wifes LG VX8600... HELP!
