I have had it for a year now. no problems with it. the ipod works so good with the pioneer units. my album covers are on the screen, and it plays well. But the best feature is the EQ, (AMAZING) if your a serious audio guy like me quality is everything. if it sounds like crap you will never like it no matter how good the product is. I had a clarion in my old show car and the EQ was terrible. Not as bad as a JVC but still bad!!! they really are dirt cheep these days. and you really do get your moneys worth!!! if you can get the AVH-P4300DVD go with it. it has way more features then the 4100 does. i think they are on ebay for around $330 shipped. but remember on ebay, Buyer beware!!!
