How can I see what POIs are updated?

uffe73

Maybe this has been discussed in some thread already, but I couldn't find it.
I downloaded my first POI updates today via MapShare which resulted in a number of new files in the map directory named CAxxxx.ov2. I assume that each ov2 file corresponds to a POI category. As I wanted to see which POIs were udated I copied these new files to a directory on my PC and tried to open them from PoiEdit. The problem is that PoiEdit reports the file as being an illegal ov2 file. The file format must be different from other POI files that you can add manually. Does anyone know how this works? Is there a way to examine these POI updates?

I'm also lacking an option in Home to chose whether you want POI updates for the whole of Europe or only for your region (your country). I'm not so keen on filling up my unit with POI files for Spain unless I'm on my way there myself.

Your slightly wrong .. the Caxxx files have come via mapshare but are tomtom corrections which maybe not poi updates..... guess it depends where your getting your pois from ... poi's as far as i know will appear as ov2 files , what i do an its a pain is to take the new file before downloading to tom tom and open in something like poledit , and compare it to the file on your tomtom ... but its hard work

Oki, you may be right. It's just that TT Home wrote on the screen that it was downloading new POIs and afterwards I had all these new CAxxxx.ov2 files. Another thing I noticed was that poi.dat and crpoi.dat were left untouched. However there was one new file named DeletedPoi.dat. If your reasoning is correct, it implies that no new POIs were downloaded but only a list of deleted ones. But how would I examine a dat file? POI-Edit for sure doesn't read that file format.

Be careful i think your at risk of corrupting your tomtom , from the filext.com website a dat file is "Can be just about anything: text, graphic, or general binary data. There is no specific structure for a .DAT file. You can use an editor like EditPad Pro to look inside a .DAT file and possible determine its contents and relationship with a program." where as an ov2 is a Program File - Overlay .. the difference the one is instruction code , the other info.[/b]

This is an approximation of what each CAxxxx is a POI for. Some of the Names have changed slightly, but the category is basically the same.

The CRPOI.dat files are the map share correction files.

Well, all I can say is that I have eight backups of my Go720 with it's original v705 map. There is a crpoi.dat file in the "day one" backup and the file size and date is unchanged in every one of the others, (and on the TomTom).

I have two backups of the v710 map and the crpoi.dat file is also unchanged.

I am subscribed to Map Share and get regular downloads. If I check the folder immediately before and after a Map Share update, the CAxxxx.ov2 files alter for any POIs updated and the ServerNameIndex.dat, ServerLineIndex.dat and MapServerPatch.dat all change too.

Believe who you like, but TomTom "support" have told people all sorts of rubbish before. (HERE'S an example from just yesterday!)
