Hi I have a dell axim x51v and a sony Ericsson k800i .The x51v has a tomtom navigator 6 card installed , which work very well . my problem is I cannot get these to connect to tomtom traffic on the move. when the x51v is connecyed to my computer via a docking station usb I can use l the traffic ok when i try to use it with the k800i I get a message "no wireless data connection" Has any one done this or has any ideas as i have tryed every thing I know and an now at my wits end.
thankyou
