    It look like a alternator problem to me. What kind testing did they perform? Do you have the testing information off your hand? How many volt does the alternator putting out? Please take a close look at your power steering pump. The power steering located directly above the alternator. If the pump leaks, which is most of the time. It the fluid will find it out to the alternator. Please provide the alternator output.

Probably anti-theft protection. The majority of cars need to have a security code input into the radio if they have been disconnected from a power source (ie dead battery, thief stealing from the car) This event makes the radio cease operation until the code has been re-entered. If I am not mistaken all functions you are describing operate through the NAV portion of the car.

If you mean you jumped/boost it you probably fried some fuses or circuts. check all fuses first. then let me know if its fuses or not.

Take a flashlight and look again under the dash.near where the plastic trim ends at knee level , drivers side I think on your car. If you have just had your tires changed or rotated your sensors themselves may need to be reprogrammed
