POI questions

Three questions,

1. First of all, does anyone know of any POIs for pharmacists/chemists?

2. Secondly, Ive read several members saying that excessive POIs could cause a problem with speed of the application.

Can anyone give me pointers on this, I appreciate it is down to your PDA, available memory etc. Was also wondering if this is only related to the number of additional POIs you download or does it also apply to the standard POIs already there that you select

So far all of my maps and POIs are installed on my 256MB Lexar SD card. I have an ipaq4150 with PPC3 which runs the xscale 400 MHz processor.

I have installed TTN3, CheckPOInt and the following POIs:

Pocket GPS speedcameras, all of checkpoints POIs which synchronised by default, code searches for glasgow & edinburgh, M6 all tolls exits & plazas.

3. Can the default POIs that came with TTN3 be deleted?

TIA.

4. And how do I delete a POI that I have installed!

1) I'm not aware of any, but you could create them yourself if you can find the lat/long co-ordinates

2) Not really with speed of the application that I've seen, but it can stop you running TTN or make you more prone to lockup's and fatal errors, there's a theoretical limit. Some say it's 20, some say 30, some say 40 OV2 files. It really depends on how much RAM you have available.

3) No

4) Deleting a group of POI's that are resident in an OV2 file, all you need to do is delete the OV2 and corresponding BMP file and you're done!

2) 64 MB RAM on the 4150. If I am running TTN3, all that will be running is the BT stack, CheckPOInt 3.2 and today in the background.

4) So I only need to delete 3 x 1kb files? Is that all that the POIs take up???

Unless there's a lot of POIs, the .ov2 files are not large (though don't forget, especially when using a memory card, the phenomenon of 'slack space' - if you have 8KByte clusters, then each file's space requirement is rounded up to the next 8KByte figure - so a 1KByte file takes 8KBytes on the card, and a 9KByte file takes 16KBytes).

The .bmp files that hold the POI icons are not large either.

And how do I delete a POI that is pre-installed?

You can't - but the built in POIs are heavily compressed and don't use much memory.
