i own a navi system coming with my car using igo maps from an uncrackable sd card.
it uses some kind of cid code.Many users has the same problem
This system also has an dvd player on board
so my question is " is it possible to change the system reading a dvd instead of the sd card" ?
Bad news. I can see that iGO app is on the internal memory, only content files are on SD card which is bad combination for modifying anything. Most 2-din Chinese systems comes with entire iGO software (main app+content) on SD card which is usually very easy to swap with the cracked version. But in your scenario it's very difficult because you don't have access to the internal memory where the main iGO app is located, so you cannot swap it with the cracked version. You also didn't mention your system brand and type but nevertheless I don't think there is much you can do. And to answer your question very straight - NO you cannot force navigation to read data from DVD drive and even if you can, that won't make any difference anyway.
there is a slim chance to hack into the system if there is a firmware update released but these days everything is protected by unbreakably long rsa keys so there is a very very slim chance to get this done unless the system design is totaly lame
Yes it's similar in Dacia nad Renault cars equipped with MediaNav navigation system an solution does exists..the unlock script is based on firmware files which are modified so you can enter into wince where the original nng.exe can be found and it can be (potentially) replaced with the cracked one..But that is a short version of explanation.
I think this will be to difficult for me.The telephone and backwardcamera are also related with this system.I've read at the dacia forum that this hack has lead to a lot of problems.I'am done with the subaru anyway i bought this car in 2014 coming with 2011 q3 maps.Can you imagine that you buy a portable tomtom coming with this old material.? I'am from the netherlands (that's why my english is not so best) where we buy this kind of cars for about 45k I'll buy a new tomtom using it for the next few months and buy me another the car a.s.a.p.(not only because of the nav system)
still hoping that there will be an easy solution in the nearby future
Unfortunately new Toyota vehicles are similar, they use Fujitsu Ten head units with only the iGO content on the micro sd card, the main program must be on the internal memory.
I have often wondered how this is accessed in the factory, is there a hidden port somewhere?
I have read that root access to some systems has been obtained by using a usb to ethernet converter but all my attempts so far have been unsuccessful. A lot of these head units have internet access through a smart phone, in Toyota's case an app called Toyota link which gives web pages for weather and Pandora radio.
If the unit can get outgoing web access surely there must be a way to get back in? anyone with an idea to try???
