Ive ordered two screens from them in the past and they both worked well. One I bought through their ebay ad, and the other through their website and I didnt have any issues. Its a lot of knock off stuff obviously but as I said no issues with the screens and that was over 3 years ago. I would imagine with technology improving so to would the quality of these devices

 

I have a Pioneer f90bt. I do like it, i think i spent 850. The only cons i have are: Its hard to see in the sunlight or bright days, and the ipod control is a little tedious. I like the newer alpines that have the large scroll wheel. With the pioneer you have to press the touch screen to go page by page through songs ect..

Bottom line 600 is a little low for what you are asking of a all in one head unit.

 

I've been looking for these but havn't found any at a price anywhere close to what your saying. Any way you could point me in the right direction?? It would be a great help.

 

sonic has it for 429 shipped its back ordered thou
