I know my bro's accord has a DVD based navi, and that there is a chip you can get so that the navi can play DVD movies. Does anyone know anything about this? (I have the stock navi) Ive tried looking around and haven't found any info on this.

 

I saw a guy at the dragstrip that had this mod to his 05 350z, so it does exist. Unfortunately i didn't pay too much attention to where he got the mod because I bought a Soundstream Touchscreen DVD only unit.
