Sales of satnav's have been dropping since the availability of built-in versions to the point where TomTom are no longer offering updates to several of their models that were advertised as having lifetime updates https://uk.finance.yahoo.com/news/t...ping-updates-66-sat-nav-models-155004021.htmlI have bought cars with built in satnav for years, I just prefer it to sticking something to my windscreen. Had wireless carplay / android auto been available for my last car purchase I wouldn't have needed to pay extra for satnav.
My guess is that car manufacturers recognise this and are all going to charge extra for carplay shortly.
