I haven't been able to find whether or not the Dension BTA 1500 bluetooth module will interfere with my 2006 e60's existing bluetooth. I'm going to install the Dension Gateway 500 and I hope to be able to use the BTA bluetooth module to stream music from my phone to the car. I spoke with a local audio shop and they warned against the BTA 1500 bluetooth module, but what I've gathered from some of the posts here, that doesn't seem to be the case. Would I have to disable the stock bluetooth and solely use the bluetooth provided through the Gateway? Or can I keep the stock bluetooth active but just not pair the phone with it? Could someone clarify this?

Perhaps I should have posted this in the mods and accessories forum instead?
