Looking for some direction.  I have a latitude rugged extreme 7220 tablet that I am using for navigation in my car. This model happens to be the one with just the antenna passthrough ports. So I have to use a USB style gps antenna.  Is there a product our there that will allow me to use the ports? I am not looking at installing any docking stations like havis just to use the ports. Just looking if there is some adapter the will allow me to use them. Also if any knows what style the connector is that would be helpful.
