Got a tomtom xl here that is badly in need off having the maps updated and just wonder what is the best way off going about it ? The navcore on it just now is 9.465 and the map is UK v860.3101. So is there any benefit for me to put a newer navcore on it and if so what one also what is the latest map I can put on it ?

Another problem with this particular model is there is no external card slot so internal memory is very limited ie. 64mb with 20.4mb free. Okay to update map to a newer one ?

Thank you.
