OnStar Navigation and Caller ID

[bluemotev]

Hello, I am curious and wanted to get some responses regarding some of your experiances with certain features. I have a 2005 Silverado with Onstar and a factory navigation system pulled out of a Tahoe. So, if you have a Tahoe/Suburban/Silverado/Etc.... with factory navigation and Onstar, please respond to these two questions....

1. If you receive an incoming call (through either the Onstar personal calling system or Verizon if you added the Verizon with Onstar service) do you get caller ID on incoming calls?

2. What does the navigation unit do when an incoming call comes in?

To answer my own questions for your reference, I do NOT have caller ID and the only thing the navigation unit does is mute, but the display stays the same... Thanks
