The 196 comes with a small data card, about 8meg, from memory. This is enough to get a couple of counties on.
Get 64meg+ to load half the UK or 128meg for the whole country.
When using it in the road, it navigates on its inbuilt low res map, so it will some times get "temporarily unsure of position" even though it is showing exactly which road you are on. This is because the low res maps are slightly topographical and don't follow the exact lines of the real road.
"Set lock to road" on for quicker navigation processing.
I saw the 296 yesterday. The best bit of kit since... er the 196
