Can "High-beam assistant" be retro fitted on my,635d ? I have auto-dim mirrors

[SpiderMacK]

Hi Folks,

Does anyone know if "High-beam assistant" be retro fitted on my,635d ?

It's a 2009 model

I have auto-dim mirrors & lane departure warning system on my car so guess I may have the necessay hardware ?

I'm thinking it may just be a software update which my dealer could do.

At a cost no doubt but if not too excessive I'd be happy to pay.

Does anyone know if this is possible ?
