Hi. I bought a Navman my500xt last week to be able to use the bluetooth feature for my mobile phone while driving, hands free, which it has. I paired my phone with it and my husbands phone as well. My phonebook would not download. The bluetooth worked to call my contact, which I had to do from my phone, but I cannot hear the person I called on the device. I tried many times with different people. I called the Navman Technical support who are offshore, who knows where, and got nowhere with the person. He told me to take the unit back as not working.
Also, I bought the Navman as was told it was a NZ product. To my disgust, the voice giving directions cannot pronounce the NZ names of streets and towns which is very offputting. I am taking it back for a separate hands free kit and a different GPS unit.
