Can anyone explain the purpose of the 10GB hard drive that you get with the Technology Package? Audi doesn't seem to explain what it is used for. Surely the only justification for a spinning drive in a moving car is because it's cheap to store a lot of data - but at a tiny 10GB, that can't be why. When two solid-state SDXC cards can store up to 2TB, it just doesn't make sense to me! Also, is it worth the extra £300 for Audi Connect? I have a spare SIM/contract with data for the next 12 months, and after that I can pay EE £5, so that element is not an issue for me. I'm just wondering if the money could be better spent on a B&O sound system, for example.
