Blaupunkt used to have one headunit that looks really stock. Its called Toronto RDM 126. It is unfortunately out of production now but you can still find used one on ebay. It has the exact same colour as the display on a BMW dashboard. Also the the panel looks clean without too much buttons, unlike the Kenwoods one. It is a medium quality headunit and it is really expensive, even for a used one. But if you want the your dashboard to look stock with an after market head unit, then the BLaupunkt Toronto is the way to go. I was contemplating on buying one but decided to wait for the new Blaupunkt Woodstock instead.
By the way, this is my first post and I must say that I have learn alot from the posts in this forum.
