Installed Rcd 310 now Bury hands free not working?

[gizm0]

Hi all, installed an RCD 310 into my ED30 to replace my RCD 300. Before I swapped it I had a Bury hands free kit installed by vw before I purchased the car but since fitting the Rcd 310 the has free won't work, it will connect tothe ophone but if I try to ring someone nothing comes through the stereo at all.
I have had someone look through it with VCDS but could jot find anything wrong or get it to work so kind of hoping someone may be able to point me in the right direction?
Thanks all

Dan

It's probably come unplugged on the bury unit. Your best to check all the wiring behind the radio

wiring is probably different compare the stickers on both radios
