This I am sure is not a smart question, but I could not find a clear answer after searching for quite a while. I recently purchased an 03' 996TT. I need to change the battery. I have no problem with changing the battery (I also have a 993). The question I have is related to the radio. My 993 has a 4 digit radio code. I have this number is a very safe place and I have had to use it a number of times throughout the years, recently with a battery change.
I have read that the 2001 and 2002 996tt models also need the 4 digit code. But I am not so clear on if the 2003 and later models require or need a radio code.
I need to replace the battery in my 03' and I was never given a radio code. Do I need to worry about this, or will it reset itself?

Thank you

 

if you have the bose/most system its ecu encoded and no need for a code. i have a 2003 and unhook the battery all the time with no issues to the radio

 

Awesome, just the answer I was hoping for!

 

+1 on an 03 with no code needed to switch out battery.
