Re: Address or POI

Hi you can try wipeing the navman by connecting it to your pc and when active synk pops up explore it and delete the programs file and the my flash disk folder. Then when you restart it will create new copys of these folders. This has worked for problems in the past for me.

How to put in address to pick up someone?

Would like to know what model you have, but have you tried typing the address in as a new destination? or try adding it as a POI(points of interest)? You may need to remove some old address's and or POI's to make more room if you can not enter it. Thanks for using FixYa

Application;Mobile navigator.exe has performed an illegal operation and will be shut down. If problem persists contact the program vendor. Program; Mobile Nav Exe Eception; oxc0000005 Address; o1b1f2dc

Application crash. On a couple of occasions, we've hit application crashes, specifically the following: "TomTom Navigator.exe has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor. Program: TomTom Navigator.exe. Exception: 0xc0000005, Address: 000b2c6c". We got this using v2.24 (361). We've seen two solutions proposed online:
  • This may be a problem with custom POI files. Check the names used - the bitmap and the datafile must have identical names: first one capital - rest lowercase.
  • One user solved the problem by removing the optional colour schemes that were obtained from the TomTom site. Removal solved the problem.
We found that reinstalling the map (not the application), solved the problem. If you get a similar crash, check the files in the map folder for anything odd.

How do I find POI for a city that I am going to visit ? I can only find POI within my vicinity. I went to where am I then programmed the new city I was going to be in but it kept looking for an address....


To find distant POI's or one close to your destination all that you need to do is when in the "Points of Interest" section under "Where To?" change the near setting to recent destination or any of the other selections.

Hope this helps!

I have the same issue on a Nuvi 350. Navigating to a POI is not a problem, whereas typing an address is not possible. My Nuvi350 is complaining about not being able to find the country...

I can't get the location of a store that I know exists. I have a garmin nuvi 200w thanks

Commercial locations are gleened from advertising medium, such as Yellow Pages, etc. If the store is very small, there's a chance they won't be listed as a Garmin point of interest. You might have to search via address.

Having problems with poi loader cant find csv file to be able to download files.unit is a garmin c31o

Here's how you get custom POI files on a Nuvi:

1. Download and install Garmin's POI Loader.

2. Create a folder on your computer, suggest Desktop, with a name like "Custom POIs". The name and location doesn't matter but you have to remember what it's called and where it is.

3. Go online and look for 3rd party POI files. Places like have dozens if not hundreds of files.

4. Select ones you want on your gps to download. Make sure you are getting the files in the correct format. Newer Nuvis use *.csv files. Not sure if the C310 does. Download your POI files into the folder you created.

5. Plug your USB cable into the GPS and your computer. Wait until the driver finishes loading.

6. Run POI Loader and follow the instructions until you get to a screen asking for location of POI files. Point it towards the folder you created. Next tell it to load the POI files. After a few seconds it should give you a message "XXXX data points successfully loaded".

You should now be able to go to POI/Extras screen and see "Custom POI Files". Open that up and your custom POIs should be there.

POI menu with custom POI does not appear anywhere on the C330?

You need to use Garmin POI loader to input custom POI. After loading POI's they will show up in "My Favorite" under "Custom POI"

Inputing addresses

Try to find a Point of Interest that's on that highway (like a Mall, Bank, Drugstore, etc.). Then, see how the address for that POI appears in their database. That will give you an idea of what shortcut they're using for that particular highway.
