I'm not sure if this topic has been discussed before, but I was wondering if anyone has used a bluetooth phone w/ their M3? I'm considering the Treo 600, which just came out through Verizon, that has a third-party SD card for bluetooth. I did some poking around and found that only a certain list of bluetooth phones work w/ BMW, and the Treo was not listed (although this info was posted a while ago).
So basically, has anyone tried a bluetooth phone? If so, what kind and how cumbersome was it?
