I did a head unit replacement not too long ago on a 2003 Mustang and it was easy.
See and I have a "New Edge" (refresh of 4th-gen) Mustang too. So you say it is easy huh? Cuz all I want are some f*cking USB ports so I can load audio from a flash drive. My car's CD drive doesn't read MP3 CDs, and it gets HOT, which causes burned discs to become unreadable. Well actually, I should probably focus on other things first, like oh I dunno, how the headlights randomly cut-off (used to be high beams but now lows too), or how both of the cig lighter plugs crapped out (the first one went ages ago, 2nd one might be fuse but I lost my kit that was full of fuses for my car), or the belt squeal cuz it's probably slipping (that's new, the current belt is not even that old), or the engine running lean (or at least that's the check engine light code I got from my pop's reader), or replace the A/C compressor pulley that won't spin (don't care cuz plain don't need A/C in most scenarios in many years). I just don't really need to drive much these days. Haven't for years, even before COVID-19. But yeah I'm tired of using a cassette adapter to play audio from my phone (and years ago, from a Creative Zen Vision-M something-or-other MP3 player, which was stolen back in 2010 among other items). My adapter has gotten wonky over the years, and now half the channels cut off. Sometimes I have to jiggle the wire or re-seat the "tape" part of the adapter to get the right channel to come back.
Do not want anything that uses a touchscreen. Can't f*cking stand those, especially in vehicles. Worse in vehicles cuz they are a hazard.
Crutchfield was a name I knew about back in the day, and used to peruse the catalogs often. So they're still alive and kickin' huh?
EDIT:
The older cars are a lot easier to replace things on
You're telling me. My car has no ABS, no traction or stability control, nothing fancy at all. Makes doing things like replacing calipers, pads, and rotors easier. Not many sensors to deal with, unlike today's cars. No drive-by-wire crap, an actual real key, and well just simple straightforward sh1t (well as straightforward as you can get when dealing with Ford nonsense) that makes maintenance easier to deal with. Taurus SHO on the other hand, f*cking nightmare. Also wish my popz would stop buying Ford stuff, but that's a whole other thing.
