I've been thinking a bit about how I want to go about an audio upgrade. Amp, speakers, sub are decided on. But I can go one of two ways with the interface:
- Dash-mounted phone. No head unit. Bluetooth direct into amp. Line level from amp to sub.
- Double-DIN w/wireless CarPlay.
I like #1 because it's stripped down. And I can use the area where the head unit used to be for a switch panel.
#2 provides more functionality... mostly a rear camera. That's the main difference, and I'm starting to think it's not enough of an advantage to go with a head unit.
There's a compromise I haven't given too much thought to: I have a Maxca unit on my motorcycle. Carpuride is a similar device. It's basically just a CarPlay screen. Audio would still have to be handled by BlueTooth to an amp.
I'm not at a crossroads yet because I'm putting off the audio for other upgrades... but it's coming.
