Where do we start,
firstly throw the nokia mic in the bin, its useless for what you want it for, youll need a genuine audi mic ( ill send you a link later, about £10 on the bay )
the mic will need to run to the rns-e marked mic in + and mic in -, then youll need to hack your rns-e upto 660, can be downloaded off the net, this will give you the SDS hack once coded.
if you dont have bose then dont worry about the ground pin, this will not affect you.
to get the nav directions on the dis, set the nav off, once your on your way, turn the rns-e off ( press and hold in the volume button ) then turn it back on again, providing you have coded correctly you will have nav on your dis.
