I bought a different radio to replace this one. Works perfectly. I just sold same radio from my GF's car for $520 plus shipping on eBay. $500 for any Prime member plus $25 shipping. Original Suggested Retail was close to $2,000. Comes with all accessories and original box. Easy install with Science of Speed plugs and mtg bracket.
