I just installed my X920BT and when the radio mates with the phone or visa versa some of the contacts come up last name first? I have checked my phone and all the names in my phone are all first names first then last name. I have erased the contacts and put them back into my phone but it still happens? Why only a few names do that? This is realing driving me crazy!! Thanks Steve T

Do you have the latest update installed on the unit?
