So I called my dealer and asked if I can get a USB cable instead of that useless MDI, and the guy said it can't be done but there's a new iphone 5 (lightning cable) available for $100 (yeah right) so I ordered a USB cable off eBay and I'm waiting for it now, I tried the SD but it was a pain and didn't work, has anybody tried a USB cable (not original USB/aux that's available instead of MDI) can you see artwork or use steering wheel controls while playing a USB stick? Or is it just like the iPod connected to MDI (charging/no controls whatsoever?)
