its easy to get parts in B5 just tap few wires going rnse
wiring harness from euro-parts.us $125
need BT module, BT antenna and possibly mic if you dont have one about $500-550
i just put BT module and wiring harness on the drivers knee bolster plenty of room under there used some velcro to hold it down.
then just power and ground which are right there at knee bolster and if you do not have telephone plug on RNS-e adaptor hook up (k, tel +, tel-, mute) wires to RNSe.
no more plug and play then that.
Install about 30min-1 hour
