Thanks for the reply, but it doesn't really tell me what I wanted to know.
Both the 59 and 62 maps are missing Cspeech, IQ, ALG, ASR and HNR and will both run on the same devices. The 62 map is not shown in the table in the reply, but can be found in similar tables in other threads. As far as I can see they are identical appart from the size of the files, so why are the 62 files bigger than the 59 files.
What I am really asking is which one should I use to get best detail and POI etc.
