If I buy a bluetooth Car Kit for the Treo 650, can I still connect my wired headphones (or cassette adapter) to play music to PocketTunes? Or does connecting wired headphones disable bluetooth? If this is expected to work, how does it work - i.e. when phone rings, does the sound come from Car Kit as well as headphones?

I did a lot of search on this, but did not see this exact topic covered.

Thanks in advance... This is a great forum.
