I'm new to 300ZX ownership so apologies for the number of questions I'm asking.
I'm acquiring components to upgrade the infotainment system, this includes an Android head unit with matching amplifier connected by SPDIF.
I understand that if my car has the Bose system I'll need a bypass, but I don't want to buy one if I haven't got Bose.
So my question is, how can I tell if it does or doesn't without taking off a door card or rear speaker enclosure?
