i finally have everything installed and sync'd up my z1 with my sprint ppc 6700 and found a lot of echo on the other end of the line like what has been discussed over and over again. i did have my phone volume maxed out when i paired my phone. i have tried to do a level 3 reset but cant get it to work. i start the car, wait for the black start up screen. then i quickly pushed and held the "map" button. i kept holding it but nothing other than a regular boot up happens and nothing is reset. what am i doing wrong?
