hey all, i have a Hitachi MMP-501 GPS device, i am runing Paralles 2.5 on my MacBook Pro and for some reason when i connect the GPS into the USB when i am in Win XP i get a Parallel Error saying that the USB device is being used by another aplication and therefore not letting me use the GPS with in parallels. i am wantting to use it with Streets And Trips but also interested if there is a way of doing it on my Mac. as in a program for OSX that is similar. Thanks in advance
