POIs show as grey dots - Garmin nuvi 310

I have downloaded the Speed camera database (Consolidated and single file) which both work fine and display the icons as expected.
However if I load PIOs as well (both from the default PIO directory) the speed cameras and some of the other PIOs are displayed as little grey dots.
I did a search on this and although it has occured before with others I don't seem to have seen a suitable fix.

Any suggestions welcome

Garmin Nuvi 310
Software version 5.00
NT+9 Map
PIO loader ver 2.53

How many categories of POI do you have? The problem seemed to occur if you exceeded 256 categories.

Thanks for the suggestion, but I was under the impression that this had been fixed in ver 3.90
I've just tried installing approx 100 categories (assuming one CSV file is one category) and all seems to work fine, so I'm confused by that one. I'll try increasing the number and see what happens

To answer my own question (appologies if this has already been covered, but a search revealed nothing)
It would appear there is a limit on the number of PIOs still.
I tried 200 and everything was fine, but when I increased this to 300 I started to get the grey dots again.
This time all the speed camera icons were displayed as it seems that the limit is based on the alphabetical listing, so "pocketgps_uk_gatso_20" is displayed but eveything from "Ramada_Jarvis_PGPSW" is not Rolling Eyes

Which appears to suggest the 256 (as per MikeAlders advice in a previous thread) category limit is indeed correct. I believe before the fix the unit would lock and freeze if you have more than 256 categories. Now it just seems to fail to show them (which is better)
