I have a 2004 XLR. How do I determine if the system is digital or anolog?
Thanks Ron M
I think all 2004 and some 2005's were analog initially.
CarterChapman is right There was a conversion package for awhile from On Star if you would activate the service. The special package and conversion was supposed to be free (ask me how I know) and when the parts were delivered to the dealer a "one time install/activation fee" magically appeared.
I sent the package back and didn't have it installed.
