I am preparing a 2GB TT XL Live for a friend to take to Spain. The unit had a 925 Western Europe map which performed OK but sometimes seemed slow in rendering. I have loaded 940 Iberia and 940 UK and ROI, the 940 UK is so that he can get used to a TT before he flies out to Spain for a holiday.
I have always been curious as to weather a smaller map file performs better mounted on the TT. Also if there is any difference in roads and other detail between say a 1.8GB Western Europe map displaying Iberia and the single Iberia map of 317MB.
