Thanks for the replies from you both but can we just back track a bit , I am sorry if I am asking stupid questions , but that's how we learn

You say " fbl, poi, fda...etc " of UK , you are assuming I understand the fda and etc bit . I am a complete Newbie at playing with SatNavs ,
so can you please explain this a bit clearer ,I have read for hours again tonight on this forum , but when you don't know what the
question is , the answer is harder to find, although in my quest I have read some very interesting stuff on here.

To make it clearer for me can you tell me :

Which files need to be changed/added and where to go on this forum to get the best replacements , a link to another post discussing
this would be fine , I will go check out the SatNav tomorrow and see whats in the folder trees to see if what you are saying makes more sense.

And then return to ask some more silly questions
