I have on my Toyota car a Embedded Gps system called "Touch&Go"


The Gps software is on an "Igo version" but the skin is very bad and map upgrade is under licence and not free.
Also, I don't know how I can't acces to the map and poi files...

Some informations about the system are here -> [Please Register or Login to download file]

Any idea how to do to unlock this system ?

Thanks.
