  • Dodge Stereo Communication Hack

    I am brand new to this forum but this seems like the place to go for what I am doing.

    I am still in the very beginning of my planning stage of a project I'm going to work on. I have a 2002 neon with the factory radio and it has CD changer controls. What I want to do is fake the existence of a CD changer to allow an axillary input. In addition to the auxillary input, I want to use input from the factory radio to control a built in MP3 player that would accept a thumbdrive. The changer control uses J1850 VPW for the protocol and the STN1110 seemed like it would be perfect for my communication to the radio.

    I found someone who has talked to the stock Dodge/Chrysler radio and has protocols for it and I feel like I should be able to use some of it:

    I am planning on using an Arduino mini Pro for the processor and "brains" of the operation. It will also use a 2x20 character LCD display to show ID3 information and status of the auxiliary operation. This is way on the back burner but I thought I would see if anyone had done this already or if anyone had advise before I when too far down a road that is a dead end.

    I haven't yet figured out what I'm going to use for a MP3 player. I've been exploring dev boards on ebay but I can't seem to find what I want. I am also new to DIY MP3 players but I would like it to be able to pipe ID3 tags to the Arduino.

    Let me know what you think.
