I saw this OEM Maxima CD/Tape head unit on eBay. Thinking it may be a good solution for me wanting to use an iPod with tape adapter. My problem is I have the RF system. Question, will this head unit be plug-and-play if I take out my RF head unit? Will the steering wheel controls still work? Any help would be great.
