deleting old files first

[Davidwf]

When I download / install to my PDA, do I need to remove the existing (old) files first ?

The reason I ask is that, on occasions I have noticed rogue icons where (mainly temp) cameras used to be but there is no warning beep or large flashing warning icon on the screen.

I have found that removing the old files first overcomes this problem but I'd have thought they would be overwriten automatically.

Any other ideas what might cause this appreciated.

Thanks

David, What nav software/ system are you using?
The Garmin devices do overwrite the POI files when you update, the TomTom devices do this as well, but IF you have switched from one database type to another (single file to consolodated or speed zoned) then the old files will still be present - this is because they are named differently. Mike

Make sure in Windows Explorer you go to Tools/ Folder Options view tab and de-select the checkbox adjacent to "Hide extensions for known file types" now when you view the memory card on the PC look at the map folder (where the POI's are stored) and any file ending with the file extension .ov2 is a POI file, there should be an identical named file that ends .bmp (the icon) - if not its probably a left over from "playing" - Mike

I think this may answer a query I posted a few days ago. I have 'played' with the databases and have upgraded my speedcamera database on my PDA running CoPilot 6. Unfortunately I made a couple of typing errors and forgot to rename a file. I now have blank POI icons on my screen and two rogue POIs in the custom menu. When I looked on the card I couldn't find them but I did see all of the other named files. I will give this a go to see if I can remedy the situation. Thanks

I also noticed that with the individual camera database loaded (i.e. a lot of POI's) the screen display slows right down and seems to update in 1 second or more "steps" rather than smoothly, also the POI warnings arrive a bit late.

My Mio P350 has a reasonably fast CPU and bags of free memory, hence the reason I tried loading the individual POI's, reducing the POI's speeds thnings up again.

Disable all the POI's this will give you the best screen refresh rate. Use "Warn when near POI" as this does still show the POI, but doesn't slow the screen down - Mike

Thanks Mikeleader.....I cannot quite see how to disable POI's and still "warn when near" - surely disabling them will also stop the warnings ?

Sorry to muscle in on your query again but as its dealing with an issue I am trying to resolve, I hope you don't mind. I have looked for a maps folder on my SD card and cannot find one. I only have 2 choices, 2577 and Copilot and its not in those. When I search the card there are no ov files on it either, just bitmaps. Strange I feel as the warnings work ok. Any suggestions.

Ah yes, I have seen this...but of course the warnings and icons are one and the same.

I have now extracted all the "fixed cams" (gatso, specs etc) into one file and done the same with all the temp / mobile cams into another file (using the excellent dumpov2 and makeov2 programs)

So now I only have 2 files with 2 warnings and 2 icons....and it runs soooo much quicker !
