Hello, GF's 2008 Sline A4 Cab has phone prep, i just need to install the blue tooth interface and what ever else is needed.. ? I am in the trade but ICE isnt my thing although im quite fluent with VCDS and coding etc. Any pointers appreciated - i will probably try and source a 2nd hand blue tooth kit unless they arent too crazy in price. Havent checked TPS as guess new they will be.. Thanks. Ps it has the 6 disk front loading Cd player - concert or symphony, think former.
