ITunes crashing during start up

Question

My iTunes keeps crashing during the start up phase. The iTunes window will start running, but as soon as the "Genius is checking your library" status bar starts running, it crashes unexpectedly.

Answer 1

...let me clarify...does anyone, have a fix that doesn't require the loss of all the information on my phone? Or know if a new update to IOS 7.2 is coming out with a fix to this?
I was asking for HELP and didn't think I was being abrasive, but some people/trolls have a tendency to read into things, and since you ask, my underwear is good to go - no knots or twists in them, thanks.
To those with constructive feedback; the car settings are where they're supposed to be. It's a new touch-screen panel for Hyundai Sonata. It was installed 2 weeks ago, they are new factory parts and system, the car system was rebooted. Then from factory settings phone has been paired and enabled it plays the music just fine, but since I updated to the ew IOS, the controls don't work. Now, on the phone itself, it has current IOS 7.2, powered down and restarted. You can't delete the iTunes Store or ITunes music app, so I checked the settings. They're also where they need to be for pairing and play. The iTunes Store crashes upon startup. I can't even get into it. I was mistaken before in my previous posting in saying that pressing the home button on the home screen twice, brought up the music controls. It doesn't. In IOS 6 version, it did. The new IOS 7.2 doesn't seem to be hands-free friendly for drivers - not like it used to be.
Phone was powered down and restarted. Under General tab in settings, all settings were reset with no change to iTunes app and Music store issues. Then powered down again. Nothing. If there is a fix for the mentioned glitches in an update, that would be great. If anyone knows of anything else, please share. Thanks.
