Volkswagen Golf Alpha 2 Safe 2 Mode
"2 safe" means that your radio was in safe mode, and then the code was improperly entered 2 times. you either need to disconnect your battery and leave it for up to 4 hours, or leave your key in the ignition for around an hour.
once it comes out of "2 safe" mode, then it will just say SAFE and give you the numbers 1-0-0-0. You just need to enter the 4 digit code (using your pre-set numbers 1-2-3-4 to change the numbers), then hold the seek > button and your radio should come on.
If you don't have the code, we can help to get the code for you. Click here for more information.
