Good alternative to Audi Bluetooth for those with OnStar

[Tom Sawyer]

Completely worthwhile mod to say the least. I had a couple calls this morning during the commute and it beat the heck out of having a headset stuck in my ear.

It probably goes without saying, but having the head unit coded for Phone but not having the telematics module in the car does cause a code to be thrown. That one doesn't bother me nearly as much as my 17125. Of course, that ends this week, dropped her off at the surgeons this morning for a little ACE TC joy.

It hasn't been tried yet, because it doesn't throw a code in my car that I am aware of, but the code probably results from the OnStar unit not responding to the CAN Bus. It may be able to be averted by plugging what remains of the OnStar harness connector back into the OnStar module. There should still be power and the CAN Bus connection is left in the connector after the migration because the BlueSTAR doesn't use it. If you have room for both where you stow it away, you might give it a shot.
