Important note for Tomtom models like VIA52/62, Start40 etc

I had a look at my VIA 135 updating gps-fix and mapshare. That with wireshark under Win7 with MyDrive; works just fine. There is quite some crosstalk between MyDrive and TomTom services via http and https, as well as MyDrive and usb-connected device via http(for status) and device port 3129(reverse-proxy for http[s]). Via that reverse-proxy port the device queries TomTom http and https services. I saw the device sending the cert or key for https queries. Sadly, my knowledge ends with saving all the traffic with wireshark. So, if anyone is interested ...

Then I downloaded the navcore ttpkg from http://download.tomtom.com/sweet/navcore/00000000-0084-0012-0710-013705962092_system-update.ttpkg{,.md5}, which is as far as I can guess the one for my device. At least it fit my device info shown from TomTom device info menu. Extracted the data and mounted the squashfs rootfs.img.new. There I found some interesting files I list here, descriptions are just guessed:

ssh authorized_keys wrote:# find -type f -name authorized_keys
./home/factory/.ssh/authorized_keys
./root/.ssh/authorized_keys

rsa key; for access to tomtom pnd https service I saw in wireshark? wrote:# find -type f -name 'pnd*'
./etc/pnd.dss
./etc/pnd.rsa

various key descriptions wrote:# find -type f -name '*.pem'
./etc/package-publickey-content.pem
./etc/package-publickey-dev.pem
./etc/package-publickey.pem
./etc/srvcerts/cpr.pem
./etc/srvcerts/ods.pem
./etc/srvcerts/pkgdownload.pem

download, verify and install ttpkg wrote:./usr/lib/jobhandlers/pkginstall

Maybe it is possible somehow that the validate_* functions return '0'?! I do not know, though.

How to generate a rsa key for signing file files:

Well, I wonder if these infos help anyhow?!

Hi All
just to let you guys know.
yes its possible with 3rd party POI as camera. via tomtom drive.
I did it on my via 135.

Hi All,

I've started with the first few lines of the first post in this topic, it's dated back to 2012, saying no solution for nc 10+ since Sep 2010. I was curious to see what happend 4 years later. But then I noticed the solution should be posted in the first topic.
We can assume that, it's very like won't be solved. The only way to fix this problem to find some bug in the making. But looks they made a flawless work
As you can see, even the Enigma machine in WW2 would not have been cracked if that hasn't had a flaw in it. Even with todays technology, if you turn the 158962555217826360000 combinations of the machine, into the easily crackable NTLM hash type, you won't crack it within 20 years,by using a residental power supply 230V x 13A, and that was a mechanical machine from 60 years ago.

Surprisingly the second hand TomTom unit prices hasn't been raised.You still can buy them for £20 with a possibility to put a 4GB card in it.Even can you turn it to a Truck,Bus navigation for less than 10% of the original price.

Is it possible to put an old 8.xx or 9.xx Navcore on the new devices?

Welcome to Navitotal.

NO!!!

Will it be possible for me to add a map (UK & Ireland) into my Start20 via a MicroSD?
I currently have Central Europe maps installed and I would like to add UK & Ireland maps into them as I will be traveling to UK soon.
Thank you!

Yes you can buy one via MyDriveConnect.

Hello,

Thanks.

Not with that model...you'll have to buy them

You better off if you buy an Android phone(won't work on a tablet) and install the 'TomTom GO Navigation GPS Traffic v1.9 (1273)' it's only 51 MB to download from torrent, than you can download selected maps through the (cracked) TomTom Go Mobile app.

ok, that's a pity..
which models does support putting US maps on?
I can cheply buy a Tom tom One 3rd Edition (4n01 .002) - will that do to get the US maps on? or a tomtom go 300, or tomtom one xl?

It's not the model that's important, it's available space of the internal drive that will be the issue because US and Europe maps are quite big.

Try and buy a model that has an SD card slot and 64MB of RAM like a Go x20, x30, x40 , x50

Hi.

I have New idea.
When I connect SD card to linux computer I show 2 files (4GB card).
I merge this files and mont.
Change map, cuple lines text files abau meta and dtc files.
Split files again.
Device (Start 60) see the map, but cannot use this map on this device.
Somebody hae some idea to generate dtc file to this device?

PS.
Command line what i was used:
cat TOMTOM.00[0-1] > tomtom.full
sudo mount -t ext2 tomtom.full /home/przemek/tomtom/tomtom-disk
{in this part i chenged maps}
sudo umont /home/przemek/tomtom/tomtom-disk
split -b 2147483648 tomtom.full new
Spited files chenge name to TOMTOM.000 and TOMTOM.001
And copy again do sd card.
