Are any of the newer Subaru stereos with aux in or blue tooth plug and play with older models that didn't come with those options? Kind of surprised noone is asking, I guess everyone who wants those just buys a new Subaru?

my 90 lego has an aux in jack... have no idea about any others tho

Oh right on, I forgot about those older ones with aux-in.

mY 91 LEG has the aux in as well, refuse to purchase an after market stereo with out one now, no matter what you need to plug in, with the jack its a breeze. The cassette adpater things were OK but the FM transmitters are carp when traveling...have to keep changing frequuencies...now need to see if Santa brought me something to plug in mine........
