Thief,
Some translations of terms in Bar Shaker's post which may be unfamiliar to you:
£ - the symbol for 'pounds', the currency we use in the absence of the dollar on this side of the Atlantic.
UK - England, plus some outlying areas you don't need to bother with. No longer includes the USA, though if you can find a Garmin UK database from the early eighteenth century it may include your local area.
Petrol - similar to gas, but much more expensive.
