I'll be changing out my battery for the first time this week on my 2004 Boxster 550 anniv S.
It was installed 3/2009 and still puts out 13+ volts at rest!!!
VIN # WPOCB29834U661077
I don't know what to look for on the label in the frunk under the insignia for the radio code. Lots of letters and numbers.
Radio manual indicates it's a CDR 23, with brand name unmentioned.
It's a Bose system.
How do I make sure I'll be able to use the radio post battery change?

Thanks in advance
