Seriously debating going back to stock the stock radio on my '89 Cutlass.
Currently have a 2006 vintage Pioneer HU with 7" screen. Low-res, plays DVDs, resistive touchscreen, has iPod control. I still think it looks cool, but it's pretty dated. I mean who plays DVDs or has an iPod any more? I don't DD the Cutlass any more, if I take it out, the wife rides with me so I don't crank up the tunes and jam out like the old days. Factory cassette HU will probably suffice.
I'm thinking should I decide to sell the car, maybe factory HU has more value than a dated aftermarket one. I'm also guessing that someone interested in an old car might place more value on it being closer to original. Even if someone does prefer an aftermarket HU, they'd probably want something modern with Android Auto or Apple Carplay, wouldn't they? I probably would if I were still DD'ing it.
