Will the steering wheel controls work with an installed phone or a bluetooth unit? Since I have OnStar will I need a GPS antenna when I add the RNS-E?[/i]

I have just confirmed that OnStar still works after upgrading my Symphony II to the RNS-E. My adapter had the wires for phone though, so did the original harness going to the Symphony II.

I don't have steering wheel controls but since the RNS-E has nothing to do with a phone kit, everything should work as before.
