Can anyone help me in regards with the text messaging feature on the s50 when connecting to my nokia 6500 via bluetooth. The problem is that when connected to my phone my incoming text messages don't display on the Navman unit, but I am able to make and receieve calls through the unit. I have noticed that the messaging button on the Nnavman seems unselectable and nothing happens. This is weird because doesn't the s50 have this feature?
