Levis,
What is your setup? I have the 510 and current ROM and VC. Works fine for VC and calls. I have not installed anything else (as I just got the phone and am also waiting on a mini sd card to arrive). I tried running the BT toggle for the 1. .net CF but although it runs, does not seem to work for me. If Media Player is running, I get music in my ear for a second before it switches back to the phone.

Thanks
Seth
