got tomtom go 500 with tomtom go maps on sd card which are registered with my tomtom go 500
had a tomtom go 300 but cant seem to find the sd card for it
now i dont know the navcore of the tomtom go300 as there is no sd card for it and it will not go to the screen which gives me the navcore version
i poped the tomtom go 500 sd card in it and it gave me the device id but want me to registered the id ,which i havent done cause its reg to my go500
how can i make another sd card with maps on it for the go300
i will need the uk and europe maps
can i update both my tomtom go 500 and 300 with this method
can i copy the go 500 sd card and use it with the go 300 or where can i get the latest map
ps i have got blank sd card and card readers
thanks
