I almost turned my old Dodge Grand Caravan into a Tesla, yup 
I used to magnetically attach my work iPhone for navigation, but the screen was too small for my imperfect vision. Long could not find a good small-sized tablet with GPS, but finally found this one: https://www.aliexpress.com/item/1005006379457345.html. Although I bought mine a little more expensive on Amazon for faster shipping and easier return in case I didn't like it.
Without the case it weighs the same as my iPhone XR (with the case), the same magnet holds it perfectly, and I can twist and turn it as I want to see everything clearly. I put the iPhone on the second magnet - purely for work email notifications and to share Internet. On my 8-inch tablet I open two applications at once - Google map in a larger window and Internet radio in a smaller window. It's very convenient, and the tablet is fast. Plus it fits in my jacket pocket and I carry it home, it's better to watch videos before bed than on my phone. Of course, it is also perfect when I use bed in my minivan - https://vanlivingforum.com/threads/dodge-grand-caravan-camper-sleeper-for-two-tall-people.38161/
This tablet is basically just a big phone, you can put a SIM in it and have normal phone calls among other things.
For about the same money on Aliexpress could be bought specially made for my car replacement for my existing old radio, with a built-in screen, but I like the option with a tablet more, do not need to install anything, plus the screen on the tablet is bigger and I can twist it as I want on the ball magnetic holder, I do not understand what the pleasure of looking at the screen that does not look directly at you. And if the sun hits the built-in screen, you can't even tilt it anywhere to see properly.
Magnets are very strong by the way, these ones: https://s.click.aliexpress.com/e/_DDwC5TJ (I took both, but I like the first model better, it is more stable on bumpy roads). I have to slide the tablet sideways to get it off the magnet, it is so strong that there is absolutely no problem with it falling off.
I also tried some other, slightly cheaper 8-inch tablet with GPS, but it was too slow and with a bad screen. I can safely recommend this ALLDOCUBE instead of the iPad Mini which costs several times more. Plus, this Chinese tablet has 3.5 mm audio for headphones and 3.5 mm AUX in the car. I prefer AUX in the car instead of bluetooth, which disconnects when I turn off the engine and then pairs for a long time when I turn it on.
Also, the iPad Mini doesn't have a slot for an extra SD card for my music library.
The battery drains pretty quickly compared to more expensive tablets, but it doesn't matter to me because I can charge it in the car.
The built-in speaker is pretty weak, so it's better not to count on it in the car. I sometimes just listen to music through sound isolating bluetooth headphones, which by the way are cheaper than an expensive silent car.
Overall, I'm very happy with the result, the tablet is good for both car and home, and in principle can replace a regular phone if your jacket pocket is big enough.
