Problem with dash display and sound after a jump start

I am having problems with my Cruze after its battery died and it received a jump start.

Any idea's what this could be? The display works for showing time/temp and radio station but no music plays. No warning alerts either or turn signal sound. Also, the display will not show fan speed/climate changes as it previously did. Any ideas what this could be? I do have an extended warranty on the car but I don't think the radio system is covered and I don't want to have to pay a diagnosis fee. Any help or advise would be appreciated!

Thanks!

Do you have any evidence to back this up? Ive never heard of this, and from a basic understanding of the electrical systems I have a hard time believing this would be true.
A car is hundreds if not thousands of little computers each running on very precise voltage and currents. When you boost your car your basically creating an inrush of current and voltage, any added current or voltage to such a precise electrical system could cause damage.

There's a reason the pros now use booster packs that have circuit protecting tech in them, and not the old school way with jumper cables.

Your alternator doesn't charge at an exact 12VDC. It varies wildly, and the electronics are designed for that. "Booster packs", if that's a portable charging pack, I believe the main appeal to that would simply be that it's portable. So you can jump yourself.
"When you boost your car your basically creating an inrush of current and voltage, any added current or voltage to such a precise electrical system could cause damage." You alternator does not create a large inrush of voltage.

Honestly you can do whatever you like with your car. But personally, I am about to graduate with a degree in electronics, so I have some experience with this, and I personally will not risk it.
