Hey there guys and gals, I have an 03 9-5 Aero that I just recently purchased without a working stereo. Forgive me if this has been answered before I just haven’t quite found the info I am looking for. I want to purchase a touchscreen bluetooth apple car play stereo with wireless connectivity to my iphone. I need something around $200 or so. My question is what do I look for when shopping for a unit that meets my needs? Any special sizing, wiring, or modifications needed to get me up and running? I’ve never installed a car stereo before but I am a music producer by trade so I am no stranger to electronics and wiring. Any and all help is much appreciated!
