Agreed. I changed the HU on my Fiat Linea recently to a Pioneer DEH 80-prs. Used Connects2 for retaining steering controls. What I lost is Blue & Me, the phone button on the steering, and the MID display showing what song is playing etc., The Windows button works ( it changes folders) My setup is as follows : 1) Pioneer DEH 80-prs HU 2) Alpine 2-way components in front 3) Boston Acoustics 2-way components at rear 4) The front is powered by an Audison SR-4 class D amp in bridge mode 5) The rear is powered by the HU amp 6) Acustika monobloc for powering the sub 7) Cervin Vega 12-inch sub in trunk. 8) Double layer Damping done for four doors and the Boot/parcel tray Running in passive mode currently, pretty happy with the front staging. Currently playing flac files from my iPhone 6 Plus. Got the install done from my regular guy in Jayanagar 4th T block (High Definition Cars). Have done many ICE upgrades on earlier cars from him and stuck to him.
