I just put aftermarket Stereo/DVD unit in my LX470...was no problem at all actually. Kept factory speakers, amp and subwoofer for now...can change them out at later date.
Will likely change speakers and subs next...then amp last as it will need all new wire run at that point mostl likely. Good luck.
Hey Brock, I am looking to do the same with my lx470. Love to get some pointers.
