Infodaptors for Aftermarket HU

http://www.caraudiodirect.co.uk/install-adaptors/connects2-ctubm01-infodapter-interfaces-for-bmw

I'm just ordering my double din HU at the moment and am shopping through the optional extras so to speak :D

Ive already added a reverse camera but have now come accross this little piece of kit. Steering wheel controls can be retained with a £5 cable so not worried about that.

But this thing works with the climate control, parking sensors etc.

Has anyone any experience with these and what else they can do / display?

I have climate control but i dont have parking sensors so i wonder is it worth my while!

Thanks,

Dillon
