I have a Viamichelin X970T, which has served me well, but am keen to get a map update. The map files on satnav are currently listed as UK+Ireland.fdp with a file type of FDP, Dated 01/01/07 and a size of 157,679kb.
Is their a way to get the latest United_Kingdom_osm.mca on to the satnav or change file so Viamichelin can read and use it or is their another map file better suited for my aged Viamichelin.
