hi guys i am looking for some info or maybe link to previous thread on this subject. i have a 2005 55 reg audi a3 2.0 tdi dsg s-line. i am looking at changing ym head unit for a RNS E that i see in a lot of a3's and looks stunning. firstly... is it worth the money that is spent on purchasing it? also what would i need to do to fit? i see that the hazard switch area is different? also is it plug and play straight into the 2 ISO connectors or is there wiring to be done? what exactly do i need to do to fit one to my car? please guys assist me thank you anthony
