This is taking way too long. I've been using a simple cradle with a suction cup since forever. Got the Tom-tom for basic navigation on the botton left corner of the windshield (it's great to always have a mini-map of the area even when not using the navigation function, you know where the intersections and odd turns are), and the iPhone suction-cupped in the middle of the console where people typically have their third party nav systems.
I can charge the phone, use it for audio, make calls (using the phone's microphone and the car speakers works excellent, I'm getting compliments on the sound quality), dictate very long text messages (thank you siri!), even switch to video recording when something fishy is happening on the road. I can use my iPhone without looking at it so it's not too much of a distraction. Knowing where every button is from daily use really helps, carPlay would defeat that. I'd love to have some sort of cradle/dock that is flush with the console where the phone is held inside the center console. Or just a sturdy dock for that matter. Preferably with some sort of OBD2-integration so the phone gets all the info from the car's sensors for better navigation and info. Easy things like suggesting to get some gas at station X when fuel is low, I have nothing in my calendar and prices are cheap right now.
But with respect; It sounds like you have an old car. Modern cars have a lot more functionality these days without the help of CarPlay.
I have a 2013 BMW and I have my navigation, phone, audio entertainment, my car power meter, tyre pressure, email, text messaging, voice command, even internet browsing and everything else built in, running through bluetooth.
The only thing I do is plug my iPhone into a charger and I don't even need to do that.
And to add, CarPlay looks very outdated compared to modern systems. Sure some are pretty crap (such as the Vauxhall / Opel systems), I've seen some amazing stuff from Merc, Audi and also BMW. These systems are leagues ahead of CarPlay.
