Looking to update my 1990 E30 stereo with something that doesn't look like a Mardi Gras disco party at night, so I picked up an Alpine BMW marked C33 off TradeMe. The only thing is, the Sony has one (quite large) input whereas the Alpine has 4.
How do I make the E30 compatible with the Alpine?
Am I going to have to chop up the nice tidy loom to separate the aerial input?
