I have a 2nd hand Snooper S2700 satnav based on WinCE 6 and uses HEAD maps
As I was not the original purchaser, Snooper T&C's will not allow me Lifetime Free Map Updates.

Does anyone know how to update the maps for free as Snooper want 135 for a new update.

Also the map data base is listed as navimap.zfs and is 3.6gb

Thanks in advance
