I have the AVH 4100NEX, I was wondering whether we can cross flash the firmware of the AVH-X8700BT to it. They are the US and its european equivalent . I want to do this in order to be able to change the tuner FM step. I also read a little bit in the AVIC mod forum but since I haven't a huge developer background I wasn't able to tell whether it's relevant or not, I noticed it's mainly focused on x000 to x100 cross flash and some maps mods. Any workaround or help to change the tuner FM step will be appreciated.
