How can i tell if my 1997 sts cadillac has on star?
ya gotta pay for it to have it "activated" with support and information~
They'll be a little antenna on the roof or push buttons on the inside rearview mirror. You can also call Cadillac's Customer Service with your vehicle identification number. They'll be able to tell you and help activate it as well. But as The Judge pointed out there is a monthly fee for the system to be active. HTH. -Jim
You can also find a button on the front roof near your glass case carrier or mirror. It's a paid service and it has to be programmed.
