"Navman does not offer map or software updates for the iCN 3xx Series/5xx Series/6xx Series/7xx Series/F20, F30, F40, F50/N-Series and PiN Series as the hardware on these older devices cannot handle the increased size of the map data or the amount of new features and functions within the new software. Navman however, makes available a Trade In Offer which will allow customers to trade in their old device for a new Mio at a discounted price. "
