I bought a satnav from netto at what I thought was a good price .

It has software on it that has a RAC sticker on it and is working very well.But I cant seem to find any site for any information or software to run updates on it .I have a tomtom that I was using before this but the screen has decided to die on it and was hoping the card would work in the new unit .Has anyone else used this Satnav or knows were I can get the updates from .
