bump will take this up again.
what BT do i need for my RCD510? only got Midline clocks. want it just to work so i can play music from spotify from galaxy s5
I think i asked similar questions earlier in the thread when I was looking to do the same thing a while ago.
Heres the info i collected at the time to help.
The 7P6 kit. Also known as the 9W7.
7P6 = (doesn't display in Highline) but works with RCD510 + RNS510, plays audio from your phone, Phone button works on mfsw and works with all phones.
Note: does display in highline if you have the polar fis advanced module :)
7P6 035 730 A/B/C/D etc
For music streaming you need a module that supports A2DP (Advanced Audio Distribution Profile, bluetooth 2.0)
7P6 035 730 B - HFP and A2DP
7P6 035 730 C - HFP and A2DP, text to speech and voice recognition
7P6 035 730 D - HFP and A2DP, text to speech and voice recognition, supports external phone cradle
HFP = Hands Free Profile (Phone still logged in, Vehicle/Bluetooth Module acts mostly as Headset)
I have the 7P6 in my car, and has worked with all my android phones.
And finally, see here for a low down on all the bluetooth modules and capabilities :)
