Did you download the a2dp.zip file from the 2nd post in this thread? In that zip file, upon opening it, there is a cab file and another zip file. That cab file is the first cab you need and then if you open that secondary zip file, it will have the 2nd cab file you need. Copy the 2 cab files over to your 6700 any way you can, through Activesync, by using your storage card, whatever is easiest for you. To use Activesync, simply hit the "Explore" button in the Activesync window, then double-click on the "My Windows Mobile-Based Device" icon and you will see the Windows folder. Once you have the two cab files on your 6700, run them each from the 6700 itself (not from your PC), put the phone in and out of flight mode, then soft reset the 6700. You need to run one of the cab files first so as I mentioned to you over PM, please read the first couple pages of this thread to figure that out. It is really a very simple process, you just need to please take the time to really read this entire thread (please don't just skim through it) and it will become very clear the steps you need to take to get A2DP working.
