My wife and I purchased our Enclave last week off the dealer lot and love it so far. One of the things that I was not aware of at the time of purchase was that it does not come with built-in Bluetooth capabilities for hands-free calling through your existing cell phone. I think this feature is more or less becoming the norm these days, at least on higher-end vehicles (e.g. I believe recent models of the Acura MDX have it). This is quite annoying since it appears that the only reason this feature is not included (when almost every other conceivable feature is included) is to encourage people to continue with their OnStar subscbription where you have to purchase minutes for calls and use a separate number. I discovered through reading the OnStar literature that OnStar has a deal with Verizon so that Verizon customers can use the OnStar hands-free calling through their existing Verizon accounts (again at an additional charge) and use their existing cell phone numbers. My wife and I have cell phone accounts with Cingular/AT&T and therefore appear to be out of luck when it comes to using our existing accounts through OnStar. Does anyone have any additional information regarding this issue or know whether there are any plans to add Cingular or other cellular companies for access through OnStar? Or does Buick have plans to add Bluetooth capablities to its list of features/options? Obviously, the great look and features of the Enlave far outweigh this issue, but it is expecially frustrating since it seems so clearly aimed at requiring people to retain OnStar and thereby depriving their customers of a normal feature on other vehicles.
