Hi, I recently started pondering the idea of upgrading my old car's stereo (which still has a CD slot I never use and only way to play music from my phone is trough Aux). So I started doing some research and soon noticed I'm somewhat overwhelmed and my expectations might be too high. For a starter, I haven't really been paying too much attention to carplay in the past (I basically only knew it exists). I soon ran into a wall and noticed that, to my knowledge, only one stereo actually wirelessly pairs the phone to use carplay (Alpine iLX-107) while all the other units, while providing bluetooth for music, require a cable connection for carplay - this seems counterintuitive. It was my understanding that you may still play music from your phone while using carplay (eg. for navigation). so what would be the advantage of BT if it only plays music, but provides no other benefit? I was especially looking at the Sony XAV-AX100 I feel like - if I upgrade, I want the best of both worlds, wireless carplay (and wireless charging, no more need to plug anything in - the dream). But the above mentioned Alpine stereo doesn't actually use BT, but some wifi hotspot connection, is that correct? (and I've read health concerns in that regard) Am I missing something? Are there, by now, more units out there that allow wireless carplay connections? Does any of you have experience with aftermarket stereo upgrades using carplay, wired or wireless?
