I have the same bad lcd panel on my car. Is there a way to tell the difference between the these,

Non I-Drive
Business HU (Option 662)
Professional HU (Option 663)

Do the units in the links above in ebay auctions work for both business and professional head units?

Isn't it labled on the front.

Isn't it labled on the front.(upper left corner)
I believe the US only has the Pro Radio.
They only time the business radio is mentioned here
is when its a Non Us poster.

pictures of the business radio in entry 1 and as you can see its labeled
and has less selection buttons and a different button layout.

If you buy a radio of ebay it needs to be programmed for the sound system
and options on your car. There are big threads already explaining this.
Also there are variations on the pro radio.

Wellps, I did mine and it seemed easy and straightforward, did everything the instructions said however the end result seems to be inverted quadrants.
My guess is one of the connections is backwards but want to make sure it's not a faulty LCD before I pull the unit apart again. Any thoughts?

You didn't transfer the orange plastic "spread plate" that is behind the old LCD display to the new display. The orange plate is what dissipates the lights from the LEDs. There is a post here showing the orange piece removed but where a little of it stuck to the LCD. Mine was not stuck at all.
Thanks for the great DIY! Very easy (if you have soldering tools and skills).

I think one of the ribbon cables is not fully seated. I'm guessing it's one of the two from the LCD display, but it could also be the one that connects the faceplate to the box. I would reseat all three. Remember the little black tabs on either side of each LCD plug pull out / down, in the same direction the ribbon cable goes out of the plug.
Thanks for the great DIY, I followed it this morning.

If you swap radio's there is about a 98 percent chance you
will get a radio that is not programmed for the sound system
and option in your car . Better to send the exitsting one to
someone that will do the Pixel repair and send it back.
Be sure to write down your Serial number if you send it in
so you get the same on back.
Getting a new one programmed can be a more expensive and
convoluted At least the above is the case for all cars past 2005.

There are services on ebay that do it for 150 which is 50 bucks
more than the kit.
