When I input these numbers at the ESC web site here is what it says. Doesn't clear up much. I am thinking the 15XXXXXX's have been superseded by the 25XXXXXX's since they have '06 & '07.

15832813 = 06 AFS CLK CD w/MP3 (Dk Gray)
15874061 = 06 AFS CLK CD w/MP3 (Dk Gray)

25780240 = 06-07 AFS Clk 6 Disc w/MP3* (Dk Gray)
25780239 = 06-07 AFS CLK CD w/MP3 (Dk Gray)

 

ChevyMgr,
Thanks for taking the time to check these numbers. I appreciate it.

 

I've got one more question.

Are the head unit colors the same on the '06, '07 and '08?
Sometimes it's hard to tell with poor photography online. I just want to make sure that if I buy an '07 or '08 unit that it will look the same as my '06 unit.

Thanks.

 

Don't forget to check with your dealer to see how much they will charge you to make it so it will play. I didn't and my dealer charged me $89.00.
