Unfortunately my car came with the eyesore that is the GSM phone preparation, dash mounted. As pretty much all phone's are compatible with the bluetooth system, really what is the point in specifying the GSM phone prep?? I'm confused why anyone would pay £385 extra for Audi to ruin the dashboard when the car already has bluetooth. Every single person who gets into my car says the same thing "oh i don't need one of those, my car's got bluetooth. It's a shame someone put that cradle thing there isn't it?". I wouldn't mind it so much if i could actually USE it. Apparently they still haven't released a cradle for the Samsung U600 which has been out for over a year. So why install technology into cars which they can't be bothered to keep updated?! Pointless if you ask me! Maybe i'm missing something here but seriously....Does anyone use the phone prep and what are the advantages?! Paul.
