LOL i got the iphone 4 cradle as a gift, but it got annoying because I would have to remove the case each time I got into the car. This is stupid.. 400 Euros for something that increases reception. PLS GO BMW
GOOD LOOKS ON THE DIY posted above. Will look into that and post results.
ALSO, does anyone know anything about Siri functionality on e90's. I was hoping someone found a way to override BMW voice command button on the steering wheel and routing it to activate siri somehow?
