2006 Prius - battery died, and after jump start, radio is acting strange.

well take a needle and see if there is a tiny hole below the part where you put the cd in,you should see a tiny hole somewhere on the face,put the needle in there till it ejects

Does the display ask for a code. Look in your owners manual. Or remove radio record the part number serial number call the dealership ask for the parts department give them the part number and the serial number. They can give you the code.

you may need to enter the radio code, if you do not have it you need to bring the registration to the dealer and they can call and get it for you. The radio locks so if it stolen it is useless.

You need to enter a security code found in your owners manual, sometimes when the battery is dead for a certain time or replaced, it goes into security mode.

battery problem, has few TSB for battery condition

Very tricky, my suggestion is to restart the radio again see if it reads the CDs this time. Try removing the radio fuse, where all the other fuses are at. Turn the radio on without the fuse, press and hold a button for a minute just to make sure you drain the electricity from the changer. Then put the fuse back and see what happens. You can also disconnect the negative or ground from the battery wait five minutes and connect it again but this will also restart the car computer.

its your battery! there are 2 the main  battery and  one for the the computer. check both to see which one it needs to be replace.

ouch thats a pricey one you have to replace the head unit there is no lock out for the buttons so if they dont work its a mechanical failure and its all one seald unit screen and all and it costs just shy of 2500.00 dollars

Unfortunatly, the Aux Battery on Prius is susecptible to premature replacements. All the Aux battery does is "power-up" the various ECU's which in turn allows the HV battery to start the car. The AUX battery does NOT operate the starter.
