@Black968. Nice car! I happen to have the correct Blaupunkt for your car… we had two restored (old timer radio in Germany) at the same time, one for our 79 928 a the other is a spare intended for our 77 911s targa, but found an NOS unit that we installed with the microphone
Btw. For this car the price is exactly what we paid for the radio and repair (have bills)…
Cheers
