In this morning I just turn on the audio to listen to a music. After 20~30 min., I tried to turn the ignition on but battery was dead! So I called my friend to do the jumping..
After that, I drove about 2 miles and I realized the whole audio system is not working at all! what do I have to do?
Nav works fine like before but there is no sounds at all...

 

you have to input the radio security code!
as soon as the battery is disconnected or appears dead the radio locks down

the nav unit gives more time before it goes into security mode

 

radio codes and navi codes needed probably...if it's not asking for the codes, take the neg terminal off the battery and reset the car

 

^^ beat me to it haha...what he said

 

it asked me to put the code so i did but i think it was just for nav. not the audio... how do i put the code for audio system? sorry to ask too many newbie questions...

 

no problem man! the audio codes - use the 1-6 pad on the radio. for the navi code, you entered it via the navi screen right? for the audio codes - use the radio pads (you know how you set 1-6 to w/e stations you like? for example my 6 = kiss fm 106.1)

 

again, if that doesn't work, undo the battery and wait 15 minutes. reattach the terminals and wait for the navi to connect to the satellite...go from there

 

thank you so much bro! you saved me! thank you!

 

what happens if you dont have the codes? im just curious

 

not a problem man

if you don't have the codes, then you'll unfortunately have to take it back to the dealership - they'll trade you your wallet for the codes -_- haha
