What is the difference between the regular pioneer cd players and the premier versions? I like the look of the premiers better, and the prices are similar per model. I am looking at DEH-P760MP on ebay. The Premier DEH-P7600MP seems to have similar features. Which one is better? ALSO these head units say that they are compatable with steering wheel controls, when you add an external adaptor, whats the deal with this? doesnt EVERY head unit hook up to wheel controls with the adaptor? [EDIT] After some research, these are the head units that I am looking at in my price range (on ebay) Sony CDX-M8800 http://sm.crutchfield.com/S-9vjCVADG...700&I=158M8800 Panasonic CQ-C8300U http://catalog2.panasonic.com/webapp...noreRedirect=1 Pioneer DEH-P760 http://www.pioneerelectronics.com/pn...891888,00.html Pioneer Premier DEH-P760MPhttp://www.pioneerelectronics.com/pn...496597,00.html Clarion DXZ745MP http://www.clarion.com/usa/product/i...oduct=DXZ745MP What are your opinions on these units? Any other suggestions are welcome, but I want to stay under $200 US on ebay.
