Hint: Use a descriptive title for your new message If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "2008 LaCrosse" isn't going to indicate to anybody that you need help. However, "Need help with my 2008 LaCrosse" will. Be as descriptive as you can. Please use common sense...

The part number for the Infotainment System manual (from my car--2019) is 84221881. You can order one from Helm (helminc.com) or you can download a PDF from Buick.com. Why a dealer can't figure this out by looking at the actual manuals (part number is at the bottom of page 2) in their inventory is beyond me.
