I am wondering if my 03 996tt needs a radio code. I have the NAV and its the first year for the MOST system. Book says i need a code for the radio and NAV yet the dealer can not find a code for it on their computer. Does anybody know for sure before i change the battery out?
Mine's an 04 with the nav. I didn't need a code when I replaced the battery. I've been told that the PCM/nav units retain the code for a few hours without power, and I've also been told they don't need a code.

Either way, I didn't have a problem.
thanks. The dealer is going to call me back tomorrow after talking to the service department. I will post what they say,
Do a google search and you'll come up with a source for your code. Or Loren on renntech can also tell you what it is. It's pretty easy to find out which sorta makes have a code useless.
on the 03 and up the most radio code is stored in the ecu and not required to be entered. It's one of the benefits of the most system. I've disconnected my battery many times with no issues

I think you're right. I didn't lose my codes either.
