I just installed my new OEM MMC navigation headunit, which i gotta tell you its awesome, to some of you guys that have this and wanna get rid of it because you may think that you dont have great sound, check again, i can easily compare this to my JVC AVX800 7 inch touch screen and quality is very close! yes i do have aftermarket subs and mids and high! Back on subject: I al looking for a downloadable version or hard copy NAvigation manual that comes with the MMC navigation. Anyone know where i can obtain one say free or really cheap? thanks
