Hi All,
Just want to say that Lawrence from Invision is just awesome

.
To make my long story as short as possible:
I bought a set of Invision headests for my X from a bmw dealer on ebay at what i thought was an awesome price. Needless to say they shipped me the wrong headrests, I have non-powered, they sent me powered, so they wont work with my seats. To make things better they would not offer any warranty on the system, since they didn't install it.
Anyways, spoke to Lawrence over at invision and ordered replacement headrest shells and some security covers, which are on their way. Lawrence was a pleasure to work with.
Anyone thinking of getting monitor headrests talk to "The Law" over at Invision. It will make your life a lot easier.
