RPO Code Question

[fmjhp594]

I got a 'GM Vehicle Build Inquiry Report' at the dealer today and it lists all of the RPO codes and descriptions plus a heap of other info on my exact truck in reference to what and when it was built with. It's a cool little report that they gave me for free.

 

Now my truck is an '03 Sierra and I have the 6 disc bose stereo in it (UC6), the bose speaker system (UQ7), and the steering wheel controls (UK3). These codes are whats listed on this report and match whats in my glove box.

 

The question is..... which bose amp do I have? Do I have the analog one or the digital one (RPO code Y91 I think)? And if you guys can't tell from the codes I've posted, can I find out some how with out compleatly taking apart my center console and looking at the tag on the amp itself? I already took out the cupholders and the closable storage bin and I see the amp, but no tags. I dont really want to rip the whole thing out to figure out which amp I have.

You do not have Y91,The Y91 "lux-amp" is only used on the Escalades and Denali's.

You have the "non-lux" BOSE amp.
