Hi Eric,I just read your post and am wondering if you might have any suggestions for my bluetooth problem. I have a new m35 and I use a Motorola V710 phone with Verizon service. I am having a problem with echo's. The person I am talking to hears their own voice bounce back at them. It is so bad at times that we have to hang up. I had Infiniti replace the mic and it seemed to help some. I also went into the dianostics and played with the volume settings. I tried High, Medium and low. Not much difference. Sometimes when we first connect the echo is there but after 30 seconds or so it can dissapear for the remainder of the call. I had verizion replace the phone but they replaced it with the same model. Not sure what to do next.Thanks,Tom
