I know this probably has already been approached many times, but just for fun I will open this for my own benefit. I have a 2012 Yellow Jacket SRT8 392 Hemi with the 730N with NAV Radio and Harman Kardon Sound System. What would be the suggested Backup Camera Kit to get that would provide the most functionality out of the Radio and it's screen? Also, how do I get any NAV software Version Updates? What is the best procedure to add Demon Eyes to the lights? Any other trick Mod suggestions??
