Is the install real easy, just remove the CD changer and it uses the same connection/cable, etc. I assume it will work jsut fine with my OEM head unit?gfeiner said:It's actually called a phatnoise phatbox. Kenwood makes the music keg using the technology licensed from phatnoise. I've got the phatbox installed in my 2003 330i. Works great, easy install. What do you want to know?
