Hi,
I have experimented with various dongles to get A2DP so that I can quickly listen to my phone or PDA when I have some new tracks and it is not convenient to upload to the empeg.
Most have been poor in terms of audio quality but yesterday I received one of these:
http://www.7dayshop.com/catalog/product_info.php?cPath=777_12&products_id=107199At £12 delivered, the audio quality is great when connected to the AUX input, and it works with all of my A2DP sources and also has AVCRP so that you can FF/REW etc.
When runniing satnav on the phone, the audio also comes out of the device, over the top of the music, again with good quality.
You do get pops and clicks as it powers up and connects but when playing music, there is no background noise, even on quiet passages.
All in all I am well chuffed with the added functionality for £12.
