: 2007 STS phone dialing without OnStar

07-29-12, 11:37 PM
Purchased a 2007 STS and never activated the OnStar system, do not have nagivation. Are there any features of the phone dialing from the rearview mirror that can be used? Is there anything I can use without having OnStar activated? Would like to, at minimum, make/receive calls through the car paired to my phone if possible. If not, would like to know what else I could use it for, if anything.

I believe only the sts's equipped with the NAV unit's has the blue tooth feature. the only thing I can tell you to try is to check under your center console storage compartment to see if you have auxiliary/RCA inputs. If So, just get the correct auxiliary cable leading from the inputs to your phone's headphone Jack.

I think there is am after-market solution. But if not, you're SOL.

It's called "blutec" oe something to that degree. It's 250.00 but allows you to use the rear view as a Bluetooth pairing device and the buttons on the rear view as mute answer or hang up. Try "blue-star" as well, pretty sure you will find it.
