I was working over the weekend restoring my app/map after a crash, and noticed something:

The North_America_2gb.tlv file in the maps folder appears to tell HOME what map version you have on your Tomtom.

Before trying any of the steps below, first backup your existing North_America_2gb.tlv file.

Then if you open up the file with notepad, search for "830" and replace it with "831". HOME probably no longer recognizes your map, and stops telling you to buy a subscription.

And you once again can see the number of mapshare in use. The number sounds awful low (905 in use), so it's possible that the number provided is an error. But the number does increase each day and I have my mapshare set to "reported by many" on a brand new map, so it's possible that the number is legit.

The file doesn't seem to be used by the application. The tomtom and Operate My Go both seem to work fine, happily reporting map 830.

If I change the "830" to "829" instead, HOME re-offers me map 830 in the "update my Go" screen, so I'm pretty sure that this file tells HOME what map you've got, and drives both the subscription screens and the update screen. Hopefully, since tomtom usually skips 5 numbers when launching new maps, HOME will recognize that August's map 835 is newer than map 831 and offer a download with no problem.

If you ever need to undo this, put back the current north_america_2gb.tlv file from your backup.

When i first downloaded the 830 na map actually during the download a number of mapshare updates appeared in the middle of the download but when the download was finished this disappeared. IT Said that their were over 5000 of new mapshares avaiable. What this means i do not know
 
I think you are going to see the .tlv if you purchased a new map and installed it.
 
There is no *.tlv in the map folder or root folder in my GO920.

The file will be located in a folder named "maps" on the root of the TomTom device, not the actual map folder where your map resides. This .tlv file is the only file that resides in the "maps" folder.

When I try and open this file on my 920/830 map with note pad all I get is a bunch of little suqares

If I use PSPad program I get about 12-14 pages of about 10 columns with the right hand column starting at 0000 then 0010 and so on going up 10 digits at a time and ending at
18B0 (1 eight B zero ) . is it in this column that I am to change the 0830 to 0831 ??

P.S. I moved the TLV folder all togather to my desk top and then restarted home and nothing changed ??

In my file there is a spot near the top that says "North"..bunch of squares..."America"...bunch of squares..."2GB"...bunch of squares..."830". The majority of the file is square gobbledygook.

It's that 830 that I change to 831.

I've also noticed that if the file is missing, HOME processes as if you have map 830 on your machine.
 
Neat trick.

It only shows that 865 corrections are in use though, and I have my slider set to "medium"

You're probably right, I had put in about 40 of my own edits, which explains my 905. My number jumped from 750 on my tomtom late last week.
 
Sorry for the size but I wanted you guys to be able to read it. This is what comes up with notepad for me. I highlighted what needs to be changed. It should not be coming up as boxes for you, nor should the file be removed from the device, only backed up.

Thanks all !!
I wasn't able to edit it with Note Pad but was able to find the 830 in the last column and edit it with a free down load program called ( PSPad. )
 
Editing tlv file

This is a very helpful find.

I was able to edit the file with Wordpad, but it did not seem to to work correctly after saving and reconnecting my 930. The box showing the map share count/New map available was not there at all. I also had errors in Update My Go, but that may have been just normal.

When I edited the file with a hex editor, the number of maps shares showed correctly, and the Update My Go worked normally.

Thanks.
 
When you edit a file such as this with any word processing program, it tends to alter the file format by adding font and size information into the file, which is why it is normally recommended to only use notepad to make any changes. A program such as Wordpad or Microsoft Word could certainly screw up a file's format. Hex editors do work too like you experienced :)
 
Here is another way.

Open and edit the .PNA file using notepad.

The .PNA file is located in the map folder.

For example, I'll use the new North American map.

Open the .PNA file using notepad and it looks like this.

ID=North_America.pna
1856196655
830
build=2284
id=303629

now add

_830

to the ID so it will now look like this.


ID=North_America_830.pna
1856196655
830
build=2284
id=303629

save the changes and disconnect from computer.

Now start the device and reconnect to HOME.
