E34 525i Radio harness

My 92 525i still has the original head unit and speakers, really wanting to upgrade it since it needs to be switched out anyways but I heard installing a aftermarket head unit can be tricky on these cars so I'm just wanting some information before I just tear into it and make myself mad

Go to www.crutchfield.com to see what fits and to see what needs to be done to make a modern head unit interface with your car. Also, check out https://www.diymobileaudio.com/forums/.
