To upgrade my options by £300 for something would never use and to know it is uselessly there each time drive car made it an easy decision to let go no matter how convenient it may or may not have proved to be (how effective with ice?) also there is a worry if insisting on Advanced Phone Pack that phone would have to be connected to it to work? something doubt very much, but why insist?
Had this been a £12,000 car, I'd think differently about the heated screen option, but in the grand scheme of things... My car is my only real vice - don't smoke, drink very little, and don't gamble. Peace of mind sometimes means more to me than what something is actually worth.
The reason why they insist on it is so that IF there is a signal issue (which I highly doubt for numerous reasons) they have themselves covered. To be fair to VW, they are not responsible for the choice of phone that people make, so if they have an iPhone like myself, it'll be basic Bluetooth or I upgrade.
