bluetooth help!
 

Okay i just been to clarity a few things really hope someone can be assistance
i have a 2008 w204. I aware of the hidden aux in the glove box but didnt like the idea of not being able to control calls and music from steering wheel. So.....

i bought the bluetooth cradle for cradle on the arm rest.
1. Can i listen to music connecting via the cradle
2. I can hear but people can not here me speak. Wouldnthere be a micro already in the car or so i need to buy one of those aswell!?!
If i can not play music through bluetooth hfp what is recommended to play music. Example Viseeo MB 4

i am now considering adding a aux. When i press the cdc it does say aux active. Do i need to run thr aux through the side panel or would it be connected through the back on my audio 20?

is there another audio 20 either integrated bluetooth.

im really sorry of im repeating questions but i keep reading conflictong answers and im not 100% sure still
