[E90rw]

I picked up a new climate control (CC) head off ebay after my last one stopped changing temperature. I figure it should be a simple plug and play.

The convertible top controller buttons (up/down) plug into the back of the climate control head unit. Upon putting in the new CC head my ability to change the temp in the car returned, but I was not able to lower and raise the the top.

Hoping someone will know:
- Does the e88 require a specific CC head unit to control the top? Meaning one from a hard top 3 or 1 wouldn't work.
- Does the CC head unit need to be programmed for a convertible?

thanks -rw
