Bluetooth audio connection is good, but connection can be choppy, takes some time to start up and connect.
Oh, and yes, use Handbrake (free to download and use) to rip DVD movies, connect iPAD to F10 via bluetooth audio, and you get a larger 9.7" display which doesn't turn off when you drive. Children can carry the iPAD with full surround sound anywhere within or near the car, how about that? Try ripping and watching 2012, it is just awesome! However, somehow there is audio time lag (pic and audio cannot sync perfectly) - anyone knows if this can be adjusted? No problems syncing if using AUX.
I also use my iPAD 3G to connect to Bloomberg and other digital satelite stations via TuneIn Radio - fantastic! Online real time streaming of worldwide stations, right into the car! I wish I could enable personal hotspot with the iPAD, this is not currently possible, unfortunately.
