[Concept2]

I just installed a Blaupunkt head unit in my 87 3.2. Looks way better IMO than the previous JVC that was asymmetrical w/ colored buttons. It does have a blue light behind the knobs which I could do without but the overall style is much more in line with the factory unit. Plus, you get Bluetooth hand free calling and streaming. I fit the external microphone right behind the wheel.
