GM bluetooth option is only available on 09 models.

 

is there anything aftermarket that could be added to make it bluetooth?

 

There are a bunch of aftermarket options you have. Some guys in the Tahoe forums are having luiking the Schoche brand that seem to integrate preety seemlesly and uses the factory steering wheel controls.

The brand that I like and orks very well if installed properly, are the parrot kits. Found here: http://www.parrot.com/usa/products/b...-free-car-kits
