<p>I just bought a new-to-me car, and when I was looking I would not consider cars with built-in navigation. </p>
<p>Cars that have those tend to drive a lot of the functions of the car through the touch-screen of the nav unit, and if it breaks, it is a multi-thousand dollar repair. For the car I got, the salesman told me that they aren’t really repairable - if something goes wrong they replace the whole thing, and it runs around $3000.</p>
<p>I remember my parents having cars with crank windows, and those broke too.</p>
