Hey guys,

Was hoping for some help with an isue I have.

2010 Golf Gti, Installed RNS510 a couple of months ago, with no drama and all working ok.
Had factory fitted bluetooth with RCD510,

Bluetooth was all working ok till about 2 months ago. Now it is all paired up and can use the screen interface to dial numbers etc, but no sound ? Both incoming and outgoing calls.
Have iphone 5 and changing between speaker- car BT does not do anything.

Anyway any help would be much appreciated.

Thanks
GG
