2013 Jetta Stereo iPhone Bluetooth Problem?

I recently leased a 2013 VW Jetta SE With Convenience. It comes with a factory standard RCD 310 stereo. I own a 16gb iPhone 4S running iOS 6.1.3 (the most up to date version of iOS as of March 19 2013) and have successfully paired it with the car's stereo through Bluetooth. The music and phone call streaming works fine, but music navigation doesn't appear to work at all with Bluetooth. When I hit the next/previous track buttons on both the steering wheel and the stereo console, nothing happens. Also, no meta data appeared on the stereo console's screen. It just says "BT AUDIO".

I tried connecting my phone to the MDI cable in the glove compartment as well. When I did this, audio navigation DID work on both the steering wheel buttons and stereo console buttons. Also, the stereo console screen displays artist and track names for the music playing, and has menus for navigation the phone's music collection sorted by artist, album, playlist, etc.

I've done quite a bit of searching but I can't find any sort of solution. I've looked in my phone's Bluetooth settings but there doesn't seem to be any preferences that enable or disable audio navigation on the car. I've also looked in the preferences of my car's stereo, but there doesn't appear to be any solutions there, either.

Is there any way I can use audio navigation with my car's steering wheel and stereo console buttons whiled paired with my phone through Bluetooth without having to get a new phone or car stereo? I'm leasing the car, so I'm not allowed to switch out the stereo, and I'd really prefer to continue using an iPhone because I like using Siri for hands-free purposes while driving.

Mobile hotspot connecting to the computer for Wi-Fi?

Here at school i keep going over my data plan because there's limited Wi-Fi here. I was told by AT&T that i can set up a personal hotspot that will connect my Iphone to my computer for free
Wi-Fi.

However, it seems that the computer is collecting the Wi-Fi via my Iphone which is just using even more of my data.

How can i set up a hotspot where my computer is the hotspot connected through a ethernet cord and my Iphone can connect to my computers internet?

My iphone won't turn on or charge

I dropped my iphone but it's still intact on the outside. It won't turn on or charge, and it doesn't appear on itunes when i plug it in my computer BUT the apple sign appears on the phone for 15 seconds, disappears for 10, comes back for 15, leaves for 10, so on and so on. I tried pressing the off and home button at the same while it's plugged in but that doesn't work. Is there anything else i can go besides taking it to apple or someone who can open it up and fix it?
