Worried about installing POI's on Nuvi 310D....

[Mr_Bee]

I got my Nuvi 310D (UK maps) in October 2006, and put the pgpsw speed camera database on it the same month.

I have just got my map update disc from Garmin and have now updated it to City Navigator Europe NT v.9.
During installation ther was no option for UK only, so it now has full Europe maps on.

I was wanting to put some more POI's on, as it doesn't seem to have many shops/banks/hotels etc. when I search for them. I saw the POI file on here with 100,000 POI's in it (here - http://www.pocketgpsworld.com/modules.php?name=POIs) and thought that looked good.

But with the speedcams on, and full Euro maps, I was a little worried about memory, and also the famous Nuvi 257 categories problem.

If I select the "Combine subcategories into category file" option, does this mean that even if I choose everything there, this will be 34 categories - well safe of the 257 limit?
Is this how it works? or is 257 subcategories the limit?
Will this be ok even with the speed cam database on?

Also, will this fit on the 256Mb SD card?

Thanks in advance :D

i currently have about 75,000 POI's installed and that takes up less than 10mb - space shouldn't be an issue to be honest.
