a jump the baterry and after that the radio doesnt work, i already check the fuses

Hello, if there was some kind of power surge during the jump start, it's possible that your radio may have become damaged. Other than that, it has to be a blown fuse -- maybe one you are not checking. There are two possible 20 amp fuses in the engine compartment fuse box to check. Left side of the engine compartment, kind of rectangular box.

If you completely lost battery power or it was so low that when you tried to crank it voltage dropped to zero the radio will have lost all memory- not just preset stations but also anti-theft code. You should see a display asking you to enter the code. Until you do that the stereo won’t come on even with good fuse. If the display doesn’t come on at all (with ignition turned on) then the fuse would have to be the problem. After finding and changing that you may still need a code to get it to work, though.
