Crutchfield and other websites list this as one of the features on this HU. I've had mine in for a week and I can't figure out how to turn it on. The book mentions nothing about it. I'm wondering if either the websites are wrong, or if it's some kind of undocumented feature..
Also anyone heard about a date on which iPersonalize will be available for the 9815? Jeeze... Alpine's slite is so outdated.
