First thing is I avoid a no name brand especially with no reviews. When it comes to touchscreen you don't want to cheap out and just buy one because it's more affordable...for example the lower class brands tend to have issue w/ the sensitivity or a delay while using the ipod more. I would check ebay and buy used if all else fails...check out pioneers line there a lot of options for slightly more. I've had 2 in the past and have 0 complaints. You can keep the door chimes if you get the correct harness...http://www.pac-audio.com has the correct harness you need im not sure if the one you linked will work.
