2001 TT Quatro question: looking online not clear to me if there's a way to modify original Bose stereo system to allow interface with bluetooth/iPhone. Thanks!

I have the same 2001 TT, and i had good luck with the following:

GROM model BT-3:
Bluetooth adapter car kit interface Audi TT 2001 (gromaudio.com)
Compare GROM Car Audio Integration Kits (gromaudio.com)

I have an Android phone, but I think they have an iPhone version.
