First of all, this is my first post here and I'll take this chance to say hello and introduce myself.
Just picked up a 2011 Overland Summit with the 430N nav system in it last week. Other car is a 2005 300C that was bought new in Dec. of 2004, so I'm a little bit of a mopar fan boy.
On my 300c I was part of a group of people that worked on the in-motion hack and actually I was responsible for developing the nag screen hack for that vehicle's REC navigation system. It was made by alpine and honestly the work on the hack wasn't too bad to do at all, just took some time and energy.
So on to the new Jeep I know I have the option of getting a lockpick system for it, but I'd also like to explore a fix from the software side of things. This way I wouldn't lose the speed indication and I wouldn't need to plug anything in to the stock system. (Not spending $250 is also a big bonus here)
I've looked around for other information and it looks like other vehicles with the MMCS have had success in bypassing some of the in-motion restrictions. Looks like they did most of their work by pulling the HDD and modifying the files that are already present on them. I've looked at the update CD that adds travel link to the system and nothing stood out as the files I would be looking for. They might actually be on that update disc, but a reference of the files that are loaded onto the HDD would be very useful for the discovery process.
I could rip the HDD out of my vehicle but I assumed others here had already done so. Any chance of one of you with the HDD out could make an image of it so I could sift through the files?
I'm not making any promises here as far as coming up with a software hack, but if I can I will and I'll provide the finished product to the rest of the group here. You can find some of my previous work on carhack.org, and I am pretty well versed in reverse engineering embedded systems. The REC had a NEC V831 CPU in it, and the current 430N has a SH-4A generation CPU, but both platforms can be disassembled in IDA easily enough.
Any takers? Just need a dump of the HDD from a 430N.
(Probably would be best with no music on the HDD as well if possible)
