Mine arrived, nice clear instructions but I abandoned the install yesterday. I popped the drivers door card off but was in a bit of a rush and instead of removing the wire from the back of the mirror control panel, I removed the back of the unit and it all fell to pieces.
So I spent 30 mins sorting that out after breaking a tab off inside it. The controller still works but the rotary button rotates freely now rather than stopping on each selection. If anyone knows where I can buy a replacement panel I would be interested, mine has got heated folding mirrors.
it was one of those days to put the screwdrivers away so I reassembled everything and will tackle the puddle light install another day without time pressure!
