Battery replacement was done in the vehicle. I think it's related to the tape code. My teacher researched a little, you would leave the radio open for about 1 hour, it would reset itself or disassemble it and re-insert it after 15-20 minutes. Of course, experienced friends know better. good forums sonerkyl 2015-09-01 14:37:03

I just bought the vehicle, I don't know if there was a battery change, but as you said, let me leave the tape open for 1-2 hours. thank you for information

You are welcome, teacher, I took a look at foreign forums and it is just our aim to help.
